Selective laser melting(SLM) is a particular rapid prototyping,3D printing, orAdditive ManufacturingAM) technique designed to use a high power-densitylaserto melt and fuse metallic powders together. In many SLM is considered to be a subcategory ofSelective Laser SinteringSLS). The SLM process has the ability to fully melt the metal material into a solid 3D-dimensional part unlike SLS.

Selective laser melting started in 1995 at theFraunhofer InstituteILT inAachen, Germany, with a German research project, resulting in the so-called basic ILT SLM patent DE 19649865. Already during its pioneering phase Dr. Dieter Schwarze and Dr. Matthias Fockele from F&S Stereolithographietechnik GmbH located inPaderborncollaborated with the ILT researchers Dr. Wilhelm Meiners and Dr. Konrad Wissenbach. In the early 2000s F&S entered into a commercial partnership with MCP HEK GmbH (later on named MTT Technology GmbH and then SLM Solutions GmbH) located inLuebeckin northern Germany. Today[when?]Dr. Dieter Schwarze is with SLM Solutions GmbH and Dr. Matthias Fockele founded Realizer GmbH.[citation needed]

TheASTM InternationalF42 standards committee has grouped selective laser melting into the category of laser sintering, although this is an acknowledged misnomer because the process fully melts the metal into a solid homogeneous mass, unlikeselective laser sintering(SLS) which is a truesinteringprocess. Another name for Selective Laser Melting is Direct Metal Laser Sintering (DMLS), a name deposited by the EOS brand, however misleading on the real process because the part is being melted during the production, not sintered, which mean the part is fully dense.[1]This process is in all points very similar to other SLM processes, and is often considered as a SLM process.

A similar process iselectron beam melting(EBM), which uses an electron beam as energy source.[2]

The process starts by slicing the 3DCADfile data into layers, usually from 20 to 100 micrometres thick, creating a 2D image of each layer; this file format is the industry standard.stlfile used on most layer-based 3D printing orstereolithographytechnologies. This file is then loaded into a file preparation software package that assigns parameters, values and physical supports that allow the file to be interpreted and built by different types of additive manufacturing machines.[citation needed]

With selective laser melting, thin layers of atomized fine metal powder are evenly distributed using a coating mechanism onto a substrate plate, usually metal, that is fastened to an indexing table that moves in the vertical (Z) axis. This takes place inside a chamber containing a tightly controlled atmosphere ofinert gas, either argon or nitrogen at oxygen levels below 500 parts per million. Once each layer has been distributed, each 2D slice of the part geometry is fused by selectively melting the powder. This is accomplished with a high-power laser beam, usually anytterbiumfiber laser with hundreds of watts. The laser beam is directed in the X and Y directions with two high frequencyscanning mirrors. The laser energy is intense enough to permit full melting (welding) of the particles to form solid metal. The process is repeated layer after layer until the part is complete.[citation needed]

Many Selective Laser Melting (SLM) machines operate with a work space of 250mm (9.842in) in the x & Y and they can go up to 350mm (13.779in) Z. Some of the materials being used in this process can include copper, aluminium, stainless steel, tool steel, cobalt chrome, titanium and tungsten. In order for the material to be used in the process it must exist in atomized form (powder form).

The types of applications most suited to the selective laser melting process are complex geometries & structures with thin walls and hidden voids or channels on the one hand or low lot sizes on the other hand. Advantage can be gained when producing hybrid forms where solid and partially formed or lattice type geometries can be produced together to create a single object, such as a hip stem or acetabular cup or other orthopedic implant where oseointegration is enhanced by the surface geometry. Much of the pioneering work with selective laser melting technologies is on lightweight parts for aerospace[3]where traditional manufacturing constraints, such as tooling and physical access to surfaces for machining, restrict the design of components. SLM allows parts to be built additively to formnear net shapecomponents rather than by removing waste material.[4]

Traditional manufacturing techniques have a relatively high set-up cost (e.g. for creating a mold). While SLM has a high cost per part (mostly because it is time-intensive), it is advisable if only very few parts are to be produced. This is the case e.g. for spare parts of old machines (like vintage cars) or individual products like implants.

Tests by NASAsMarshall Space Flight Center, which is experimenting with the technique to make some difficult-to-fabricate parts from nickel alloys for theJ-2Xand, show that difficult to make parts made with the technique are somewhat weaker than forged and milled parts but often avoid the need for welds which are weak points.[3]

Selective laser melting or additive manufacturing, sometimes referred to asrapid manufacturingorrapid prototyping, is in its infancy with relatively few users in comparison to conventional methods such as machining, casting or forging metals, although those that are using the technology have become highly proficient. Like any process or method selective laser melting must be suited to the task at hand. Markets such as aerospace or medical orthopedics have been evaluating the technology as a manufacturing process. Barriers to acceptance are high and compliance issues result in long periods of certification and qualification. This is demonstrated[when?]by the lack of fully formed international standards by which to measure the performance of competing systems. The standard in question is ASTM F2792-10 Standard Terminology for Additive Manufacturing Technologies.[citation needed]

The use of SLS refers to the process as applied to a variety of materials such as plastics, glass, and ceramics, as well as metals[citation needed]. What sets SLS apart from other 3D printing process is the lacked ability to fully melt the powder, rather heating it up to a specific point where the powder grains can fuse together, allowing theporosityof the material can be controlled[citation needed]. On the other hand, SLM can go one step further than SLS, by using the laser to fully melt the metal, meaning the powder is not being fused together but actually liquified long enough to melt the powder grains into ahomogeneouspart. Therefore, SLM can produce stronger parts because of reduced porosity and greater control over crystal structure, which helps prevent part failure[citation needed]. However, SLM is only feasible when using a single metal powder.

A Consideration of EBM versus DMLS Industrial Metal 3D Printing Processes Part 1

EBM vs DLMS 3D printing technologies

There is no escaping the fact that industrial 3D printing with metal is an increasing application trend for additive manufacturing technologies.

The capabilities of 3D printing with metal have improved dramatically in the two decades since it first became possible. In terms of longevity, two metal processes have been around since the 1990s DMLS (Direct Metal Laser Sintering) and EBM (Electron Beam Melting). As a result, a frequently asked question is: which one is best?

You probably wont be surprised to learn that there is no easy answer to this question. As with all 3D printing processes selecting the right one usually depends largely on how it is to be applied. That said, here I am going to take a timely look at both DMLS and EBM to highlight both the similarities and the differences and what this means for how they are being and can be applied in industry.

Lets start with the obvious both EBM and DMLS are industrial metal 3D printing processes that utilize metal powders to produce near net shape parts/components by way of additive layer technology. And these acronyms are both proprietary to the companies that have developed the respective processes.

Arcam is the sole owner of Electron Beam Melting, or EBM. Founded in Gothenburg, Sweden in 1997, the first commercial EBM platform the EBM S12 was introduced in 2002. Since then the company has relentlessly continued its R&D, with specific focus on dominant vertical markets, specifically in the medical and aerospace sectors. Today, Arcam has EBM installations throughout the world, still predominantly focused on aerospace and implant applications and has established a new base in the US as of 2015.

Process: As stated, the Arcam EBM process builds functional metal parts layer by layer using metal powder. What differentiates this process from all other metal 3D printing processes is that the powder is melted by a powerful electron beam (typically around 3,500 watts) to produce precise, often complex, geometric shapes directly from a 3D CAD model. Due to the use of the electron beam as the heat source, parts are necessarily built under vacuum conditions and at elevated temperatures.

Arcam sample metal 3D prints (medical implants)

Good material properties, in particular fatigue properties.

No limitations in chemical composition.

Minimal residual stresses due to high process temperature

Little waste material: virtually all excess powder can be recycled.

The Direct Metal Laser Sintering, or DMLS, process belongs to EOS Gmbh

Electro Optical Systems. The history of EOS is somewhat more complicated than that of Arcam. The company was founded by Dr. Hans J. Langer and Dr. Hans Steinbichler in Germany in 1989, with Steinbichler bowing out the following year and Dr Langer still at the helm today. EOS originally developed stereolithography (SL) polymer resin additive processes; with laser sintering not emerging from the German manufacturer until 1994 when it commercialized its EOSINT equipment for plastic powdered materials. Over the years a great deal of litigation has taken place, largely in the background and particularly around the SL process, however the companys commitment to R&D has never faltered and the first EOSINT platform for metal materials was unveiled in 1995. At this time it is fair to say the metal process was rudimentary and no where near the sophisticated, production grade process that it is today. Moreover, during its 20+ year history, EOS has greatly expanded its materials development and has the broadest metal material palette for AM, including a partnership agreement for the processing of precious metals with Cooksongold, established in 2012.

Process:DMLS is the oldest industrial metal additive layer manufacturing process that uses a precise, high-wattage laser to sinter powdered metals and alloys to form accurate, complex and fully-functional metal parts directly from CAD data. Today, the sintering terminology lingers due to it being the historical proprietary process name given by EOS rather than it being an accurate description of the current process, which actually involves almost complete melting of the metal powder to produce fully dense parts. Thus, it is also pertinent to note that the DMLS process is very similar to the laser melting processes of SLM Solutions, Realizer and Concept Laser et al.

DMLS metal 3D printing process in action

Finer layer thickness (typically 2040 m, compared with 5070 m for EBM).

Better accuracy as a result – typically DMLS produces a smoother surface finish than EBM. Raw DMLS parts have a surface finish comparable to fine investment cast parts.

Part two of this series will compare the two processes directly.

Silicon Valleys Tytus3D launches sub-$300K metal 3D printer to rival EOS SLM Solutions

Silicon Valley 3D printing startup Tytus3D has developed its first metal 3D printer. At under $300,000, the Tytus 3D printer can print with a minimum layer height of 20 microns. The company says its machine is easier to use than EOS and SLM Solutions 3D printers.

Claiming to offer a 3D printer that is both cheaper and more user-friendly than comparable machines from EOS, SLM Solutions, and TRUMPF, Silicon Valley newbie Tytus3D isnt treading lightly.

Company – Metal – Printer – End – PriceAnd at under $300,000, the Californian companys new metal 3D printer is certainly on the fairer end of the industrial price spectrum. But does the unproven contender have the specs to justify that six-figure sum?

To provide the best machine operation experience, and to reduce the total cost of ownership, the Tytus3D attempts to design and materialize innovations including patents and patent-pending technologies, says Tytus3Ds Hon S. Yi.

Look – Basics – Tytus3D – Printer – LaserLets look at the basics. The Tytus3D printer uses a laser powder bed fusion (L-PBF) deposition system, including a two-way re-coater mechanism. The 3D printer is compatible with Inconel and both reactive and non-reactive materials.

According to Tytus3D, the new 3D printer is also easy to use for production, and ready for smart factory use. These claims arent exactly verifiable from afar, but the company gets into more specific matters by also detailing the machines versatile GUI, remote monitoring capability, and other features.

Worlds largest SLM 3D printing facility opens in Aachen Germany

The Aachen University of Applied Sciences and the Fraunhofer Institute for Laser Technology ILT have opened the worlds largest selective laser melting (SLM) 3D printing facility, located in the new Digital Photonic Production industry building on the RWTH Aachen campus.

Party time: (l-r) Prof. Dr. Doris Samm, Prorector for Research and Innovation at the Aachen University of Applied Sciences; Prof. Dr. Andreas Gebhard, Dean of department Mechanical Engineering and Mechatronics at the Aachen University of Applied Sciences; Prof. Dr. Reinhart Poprawe, Director of Fraunhofer Institute for Laser Technology ILT

Maybe its the Alps, maybe its the excellent beer, or perhaps its the world-class technology on offer. Whatever the reason, theres something about Germany thats highly conducive to SLM and other metal 3D printing processes. The European country boasts a wealth of additive manufacturing heavyweights, includingEOS,SLM Solutions, andConcept Laser, and can now lay claim to another honor: being home to the worlds largest SLM 3D printing facility.

The landmark development comes courtesy of the Aachen University of Applied Sciences and the Fraunhofer Institute for Laser Technology ILT, who opened the doors to the massive new additive manufacturing facility on June 1.

Fortunately, Germany knows how to celebrate as much as it knows how to build a 3D printer, and some 40 guests from industry and research were invited to attend the official opening of the SLM 3D printing facility.

According to the two founders of the SLM facility, Concept LasersXLine 2000R selective laser melting systemwill play a pivotal role there. Thanks to its extremely large build envelope (800 x 400 x 500 mm), the XLine 2000R can manufacture metal components with a maximum volume of 160 liters.

Concept Lasers XLine 2000R 3D printer will play an important role at the new SLM facility

The XLine 2000R will be at the center of the SLM-XL research project, which is intended to accelerate and optimize the entire manufacturing process for large 3D printed metal components. There are currently 15 projects partners from multiple industry sectors working on the project.

The Aachen Center for 3D Printing is relying on teamwork to conduct the three-year SLM-XL research project, Fraunhofer ILT explains. Local small and medium-sized enterprises (SMEs) as well as renowned additive manufacturing companies are collaborating with experts from the University of Aachen and Fraunhofer ILT to achieve important goals.

The SLM-XL project will have two main goals: to accelerate the production of large-volume functional prototypes (for the automotive industry, for instance) in order to shorten the development processes, and to 3D print large-volume tools that are adapted to provide custom functions. These 3D printed tools will be either impossible or very difficult and expensive to manufacture using conventional manufacturing processes.

The new joint SLM facility offers SMEs the opportunity to implement their own additive projects on an XXL scale using a facility that costs two million euros, a price tag generally too high for any individual company, commented Sebastian Bremen, team manager SLM productivity at Fraunhofer ILT.

Thanks to the Aachen Center for 3D Printing, SMEs now also have access to a technology that can make them more competitive and innovative. In addition, this unit is another important step towards establishing a joint research group between Fraunhofer ILT and the University of Aachen.

4 Stratasys private acquisition candidates

In arecent interviewwith Bloomberg, Stratasys Chairman Scott Crump stated the companys intent to further develop 3D printing with metals.

Because there is so much opportunity we also will selectively grow though M&A, Crump said. We have an organic project to get Stratasys into additive metal. Its rational to say that through M&A we want to expand with different technology on a dual path.

In aprevious post, we looked at 4 publicly traded companies involved in 3D printing with metals. Would any of these companies be an acquisition target for Stratasys? Renishaw has only recently invested in 3D metal printing technology and they are a diversified company. 3D Systems would  involve a merger of two industry leaders. ExOne had a recent IPO and has a rich valuation. Arcam has a small market cap currently and a reasonable valuation..

However, there are still a number of private candidates that Stratasys could potentially acquire.

In anearlier postwe discussed how Optomec has been working with Stratasys on a joint development project to merge 3D printing with printed electronics. Optomec recently announced a low cost offering in its line-up of metal 3D Printers named the LENS 450. In addition to the LENS 450, Optomec also offers offers the LENS MR-7 for research and development, and the LENS 850R production repair system. Materials supported include titanium, stainless steel, nickel, cobalt and other alloys.

EOS is a German company that first developed the very samedirect metal laser sinteringtechnology that Optomec uses today. The company offers printers that support plastics, sand, and metals with theEOSINT M 280being the flagship metals printer. According toan articleby Rapid Ready Technology, the company has about 1,100 installed systems worldwide, with revenue in 2011 of about $124 million.

We have about 400 employees around the globe, with approximately 300 residing at our headquarters, says Andy Snow, North America regional director for EOS. Out of that 300, about a third of them are dedicated to research and development, and engineering. The remainder are spread out at technology centers around the world. According to Snow, direct metal laser sintering (DMLS) represents the majority of EOS systems sales.

SLM is a German company offering a series of 4 different 3D metal printing machines. The 10 metal materials supported include titanium, stainless steel, aluminium, and cobalt chromium. They recently announced the establishment of a subsidiary in the US with the company now having direct representation in 38 countries worldwide. The company uses a process calledselective laser meltingwith which they are said to have entered into a commercial relationship with the inventors in the early 2000s.

Established in 2000, Concept Laser specializes only in machines for building in metals, working directly with materials such as Titanium, Aluminium, Inconel, Cobalt Chrome, Stainless Steel, and a range of DIN standard tool steels. InMay 2013it was announced that Concept Laser and EOS agreed to a cross-license that gives each party license rights to the current patent portfolio of the other party. Under the cross-license agreement, Concept Laser and EOS also agreed to withdraw all patent opposition cases that were pending between them. The technology used by Concept Laser referred to as LaserCUSING seems similar to that used by SLM and EOS.

Acquisitions are an altogether diverse story. These regularly happen when a bigger organization buys a littler organization. Otherwise called a buyout or a takeover, acquisitions are for the most part cordial, yet in a few cases, they may be viewed as threatening. There is dependably the likelihood of mass layoffs and terminations with a securing. Earlier arrangements are here and there rendered useless as the bigger organization pushes its control over the more modest one. By and large, the bigger organization holds the name, while the more modest organization must assent to another titling.

CEO CFO Replacements at Stratasys, MakerBot SLM Solutions: Why All the Executive-Level Shakeups in 3D Printing?

byJoris PeelsJan 27, 20173D PrintingBusinessEditorials / OpinionsEducationMetal 3D Printing

The 3D printing market has seen a lot of growth, development and commotion of the past months. With growth spurts come growing pains. Over the past four weeks weve seen StratasysCFO Erez Simha, SLM Solutions CEO Markus Rechlin andMakerBots CEO Jonathan Jaglomall leave. Why the sudden spate of C-level executives leaving large 3D printing companies?

As our industry continues to mature, executing on corporate strategy is becoming increasingly difficult for some established players. In the Hype Years of 2008 to 2016 it was full steam ahead for the entire industry. Almost anything your marketing department did would get picked up by media, news reports around 3D printing were almost continuous and life was simple. Corporations and startups alike basked in the media attention and grew quickly. Tens of thousands of new customers bought printers as companies the world over took an interest in 3D printing. With very little established knowledge of 3D printing available in the market, whatever your R&D department cooked up would sell. There were plenty of customers for everybody. There was no real need to differentiate your product or work hard in sales or product development. For much of the Hype period many companies biggest problem was figuring out how to make enough machines to fulfill demand. Many startups were doubling year on year or growing by 30% per month. Two-person teams became companies with 100 or more employees in less than a year.

Now we have a much more mature market. The landscape is dotted with 3D printer startups and new market entrants. Potential customers have more knowledge, but also much more choice. The plethora of competing 3D printing companies is leading to a period of hesitation. Many companies have bought their first printers and are now evaluating them. Some are disappointed with the technology or the devices that theyve bought. Others are moving to integrate 3D printing more in their production or product development process. To buy a 3D printer to play with is easy but to industrialize the technology is very difficult. Certification, dialing in materials, reducing error rates and quality control are just some of the problems these companies are facing. Moreover they often do not have the requisite skills to industrialize a 3D printing process in house. This is one of the reasons whyStratasysandEOSfor example both have consulting services that they offer to customers. Their consultants are needed in order to help customers design for 3D printing and set up things such as quality control. The flood of customers has receded but those that are interested now are looking at integrating 3D printing in their product development process or producing end-use parts with 3D printing. The level of investment and commitment needed takes time. This is causing large deals and implementations to lag behind expectations. Large deals are often delayed or dont come to pass. This is wreaking havoc with peoples sales numbers. This in turn makes future revenues difficult to predict and seem uneven. That makes investors and shareholders nervous. What most probably happened at SLM, MakerBot and Stratasys was that given the unpredictability of new large 3D printer implementations each executive was not able to with sufficient accuracy estimate revenue properly.

Desktop 3D Printers Are Bought by Companies

In 2011 thousands of Business Development Managers bought desktop and industrial 3D printers to play with them. Now weve got compliance teams pricking holes in 3D printer performance. Startups often came to market making machines for Makers. Theyre only now beginning to find out that approximately 75% of desktop machines are actually being bought by companies. These companies want more reliability, better tolerances, lower part cost, easier maintenance, higher throughput and a whole host of things that desktop 3D printers currently do not have. Desktop 3D printer OEMs seem completely caught off guard by clients trying to use their machines to manufacture parts. It will take time for them to upgrade their machines sufficiently and implement better software and things such as print farms.

Weve gained so much at the expense of our innocence.

Despite all the media talk of everyone being able to use 3D printers to make anything the reality was rather more sobering and disappointing. Amidst claims of large multinationals adopting 3D printers throughout their engineering departments the performance of desktop machines was inadequate. Most desktop machines had failure rates of 50% or higher. 50% or greater of all prints started failed. It sometimes took more than twenty minutes to replace a blocked nozzle. Low-cost parts such as fans broke regularly and machine reliability was terribly low. We also collectively forgot to tell the media that 3D printing is very very slow.MakerBotwas selling people a dream of a microwave for stuff. Meanwhile in the real world, getting a 3D printer to actually print was a tough slog. Amidst this a focus on growth meant that a lack of attention was paid to quality and engineering.MakerBot developed quality control issues. Units were arriving to customers dead on arrival and faith evaporated. Simultaneously a backlash against MakerBot was ongoing in the open source 3D printing community. MakerBots decision forgo open source led to many overnight turning from fanboys to harsh critics. The company had over time fired key people in engineering at a rapid pace. This meant that it did not institutionalize learning key lessons in 3D printer development. The companys Smart Extruder was a dud sometimes only lasting 20 hours and with 80% of the units returned to the company. Coupled with employee discontentment and increased competition, MakerBot was in freefall.

Jonathan Jaglomwas parachuted in to fix all of these problems. A former marketing and sales manager at Stratasys, he had been responsible for Stratasys Asian business. He also developed Stratasys channel partners helping build its reseller network and running customer support. In the company hed tackled difficult issues before, now he wastasked in saving MakerBot. He reorganized the company, brought back quality control and better manufacturing practices. Ambitions and headcount were downsized but the 3D printers got better. Heoutsourced production to contract manufacturer Jabiland reorganized the company. Now MakerBot is healthier and once again on a solid path forward. Parent company Stratasys however still needed MakerBot to be successful. MakerBots shift infocus towards education and businesseswas good but the unit still had to contribute to earnings. Revenue at MakerBot was still down by more than 50%. This probably led to Jaglom, even though he saved the business, being replaced (along with the stated reason to spend time with family). Now the unit can focus on growth and maybe contributing to earnings at one point.

A positively serene individual looking at the output of a Stratasys Fortus industrial 3D printer.

Stratasyshas consistently written down the book value of MakerBot. The goodwill impairment charges theyve taken on MakerBot are now higher than the purchase price of the company. Stratasys CFO Erez Simhas abrupt departure has been hastened in part by this. The former Orbotech CFO had been with Stratasys since 2011. Simha was one of the key architects of the Objet and Stratasys merger. Many were surprised when the much smaller Objet did a reverse takeover of Stratasys. Former Objet staffers then took key positions in management. Underformer CEO David Reisthe company started to move aggressively forward. As well as the MakerBot acquisition Stratasys thenacquired Solid Concepts and Harvest. Solid Concepts cost $295 million and brought one of the worlds largest 3D printing service bureaus to the fold. Another large service bureau, Harvest Technologies was acquired for $27 million in stock. Both Solid Concepts and Harvest Technologies were some of the most experienced 3D printing companies in producing end-use parts. In addition to revenue from machines Stratasys was now strengthening itsRedEye 3D printing service businessand becoming one of the largest 3D printing service bureaus worldwide. Revenue from services was robust and let the company grow. MakerBot revenue did not grow apace with expectations, however. The company missed revenue targets and disappointed shareholders. Reaching highs of $136 in 2014 Stratasys shares are now just shy of $20. The aggressive high growth strategy deployed by the Objet team seems to have fallen short of expectations. The consumer 3D printing revolution simply did not happen in an expected way. Meanwhile industrial 3D printing adoption was slow since companies had so much that they needed to learn. Revenue growth at the company seemed to stagnate in numerous areas. This disconnect between expectations precipitated Simhas leaving of Stratasys.

An SLM Solutions SLM 500 metal 3D Printer with depowdering and material recycling.

SLM Solutionswas a smaller player in the 3D printing metals market. The German company was generally behind EOS, Concept Laser and Arcam in prominence and revenue. EOS GmbH is the market leader in plastic selective laser sintering machines and the market leader in metal 3D printers (although as of this year the leader may become GE). The metal 3D printing market was a rather tiny clubby affair of small companies selling maybe 100 or so machines a year to universities, dental companies, orthopedics manufacturers and some aerospace companies. When in 2012 GE acquired Morris Technologies the industry was in awe of the technology giants interest in 3D printing. GE took approximately a quarter of all 3D printing service bureau capacity offline, reserving it for themselves. Service bureaus and the OEMs that made the machines were awash with orders. Companies could not produce enough machines and were met with increasing numbers of new customers attracted by the 3D printing hype. Increased government funding in China and the US in metal 3D printing for aerospace also increased orders. SLM Solutions looked like a laggard at first. Their print quality increased considerably though and their larger systems such as the SLM 50 were just what the market was looking for.

Whereas previously only orthopedics and dental companies had been doing large-scale production of end-use parts, now it was the aerospace industry that wanted to industrialize manufacturing with metal 3D printing. Existing machines were very much lab machines with lots of settings and customization but low throughput. These new customers wanted automated depowdering and finishing steps, quicker builds and more efficiency. They were looking for quality assurance and testing procedures. The first few generations of machines would have to be radically improved to meet these new customers demands. They wanted much larger manufacturing machines. SLM Solutions, along with help from investor Parcom and an IPO, was able to obtain the money to make the right investments building ever larger machines and making a quad laser technology available to increase throughput.

The company posted impressive numbers with revenue growing from 11.9 million in 2011 to 66.1 million in 2015. Gross profit went from 5.9 to 36 million over the same period. Those seem like very impressive numbers. So why the sudden departure of CEO Markus Rechlin? Hed been with the company for years and his performance seemed stellar. Speculation initially was that shareholders such as Parcom or Management Board member Henner Schöneborn were upset thatGEs $703 million acquisition of SLMdid not go as planned. The anchor shareholders such as Parcom and Mr. Schöneborn (and his sons) had agreed to sell their shares to GE and were happy with the 38 Euro acquisition vestor Elliott Management, however, was notand wanted to negotiate for more. GE balked and walked away from the deal,buying Concept Laserinstead.

We reached out to SLM Solutions to find out more and a spokesperson told that, the change of personnel was not connected to the failed takeover attempt by GE in 2016 in any way. This is rather puzzling. SLM Solutions announced that it removed the CEO with immediate effect. Although he is being replaced temporarily by CFO Uwe Bögershausen, no replacement was found in advance. Additionally there was no cuddly language about wanting to spend more time with his family. Just a straightforwardannouncementthat the board took the, decision today to remove Dr. Markus Rechlin from his position as CEO and from the Management Board of SLM Solutions Group AG.  The board also, thanks Dr. Rechlin for his many years of dedicated and committed contribution to the company.

The company did miss expectations in the last quarter of 2016. Revenue was expected to be EUR 75 million to EUR 80 million (previously: EUR 85 million to EUR 90 million). Was that enough for Dr. Rechlins sudden ouster? Perhaps. Given Uwe Bögershausens degree of power as a leading shareholder and management board member a simple falling out between these two could have brought along something similar.

If we look at SLM Solutions competitive position in 2016 the company was sitting pretty. EOS was larger and competing directly with it in increasing the automation and size of the metal 3D printers. Arcam was doing well with its own technology and Concept Laser was smaller but growing. Each of these companies knew that GE would at one point most probably acquire one or more of the others. Now in 2017 we know that GE has Arcam and Concept. It will buy hundreds or perhaps thousands of its own metal 3D printers.The industry giant has committed itselfpublicly to industrializing metal 3D printing for aerospace. EOS continues to do well and new competitors such as Additive Industries are starting to make their presence felt on the market. The once clubby industry is starting to feel a little lonely for the people at SLM Solutions. If GE makes inroads in saving considerable weight on aero engines by using 3D printing a response by other engine manufacturers is likely. Surely they will as GE see that the quickest path to market and surest way to industrialize in metal would be to acquire a metal OEM. There will be other opportunities for SLM to sell itself should it wish. The path forward for SLM as an independent company looks more complicated however. To industrialize metal machines that can compete with EOS and GEs offering in reliability, repeatability, QA, throughput and automation will require significant investments. Perhaps after not getting the team the exit that they wanted and missed expectations, it was in that area that Dr. Rechlin did not succeed? SLM needs a partner or considerable new financing to compete in a race with privately held EOS and the very public GE. Without selling itself it will have to take on debt or find another way of financing itself. Missing expectations while seeking additional funds could be a herculean task. Not succeeding at this is the most likely reason for Dr. Rechlin to leave so suddenly.

To take a completely new (to you) manufacturing technology and implement it in an industrial setting with good output requires time and money. Deals and implementations of this kind will be large but chunky. These types of engagements are costly, time consuming and may be delayed. This is causing revenue numbers of companies in industrial 3D printing to be uneven and less predictable than people would like. Missed promises as a result of this, most probably, led to the sudden leaving of Markus Rechlin at SLM Solutions, Erez Simha at Stratasys and Jonathan Jaglom at MakerBot.

In 3D printing whats the difference between selective laser sintering (SLS) and selective laser melting (SLM)?

In 3D printing, whats the difference between selective laser sintering (SLS) and selective laser melting (SLM)?

, 3D printing consultant for additive manufacturing & 3D printers.

It depends on who you ask. Some people use the terms interchageably, others maintain that there are sharp differences between them and others think that it is just a bunch of Germans who used to all be friends playing word games in English.

In the beginning the general principle behind both DMLS and SLM was patented by Pierre Ciraud and later Russ Householder. Carl Deckard who later went to found DTM then actually made the first SLS machine followed by EOS. EOS later together with partners commercialized DMLS. Then a whole bunch of Germans got together in a group to work on the technology. They then split up. Trumpf got the patent for single component metals. EOS obtained almost all the relevant DMLS patents. The technology called SLM was developed by two scientists of the group that would go on to found Realizer and SLM Solutions. ConceptLaser uses the term LaserCusing and has patents on the technology while the technology is remarkably similar to SLM lets say and was developed by another member of the group.

The processes are identical with an object is built up layer by layer by a laser selectively melting a powder in a powderbed in a build chamber filled with an inert gas. The difference is that SLM achieves a full melt while DMLS sinters the powders. This means that DMLS only works with alloys (nickelalloy, Ti64 etc.) while SLM can use single component metals such as aluminium. This is not a process limitation or difference however but rather a patent issue. EOS doesnt do it because it doesnt want to infringe and the SLM guys are all either pals with Trumpf or keeping their fingers crossed that Trumpf & co. doesnt come after them.

Essentially there were several companies and institutes developing these technologies and they had a falling out and now due to marketing and patent issues they all refer to the same technology by different names.

NB, generally SLS or LS is the term used for laser sintering of plastics while DMLS is used with metals. SLM is also a term for metals and a synonym of DMLS.

Is this answer still relevant and up to date?

Selective Laser Sintering (SLS)is anadditive manufacturingtechnique that makes use of a melting laser beam to fabricate solid 3D objects. The process has been developed in 1980 by Carl Deckard, a student at the Texas university, together with his professor Joe Beaman .

The parts created throughSelective Laser Sinteringcan be made out of high performance materials such as Prototech,(aluminium filled nylon), Protoplus (standard polyamide) and Protoglass (glass-filled nylon) .

TheSLStechnology is ideal for the fabrication of small production batches and prototypes of large dimensions, whose parts are assembled and finished in our post-production department.

TheSelective Laser Sinteringallows to produce both functional and aesthetic prototypes with the desired surface finishing.

Direct Metal Laser Sinteringis anadditive manufacturing techniqueable to fuse together fine powder layers using a laser beam. TheDirect Metal Laser Sinteringprocess is suitable for the creation of metal components, both pre-series ready for testing and final production parts. The materials are fit for post-machining operations, such as milling, CNC turning, thermal treatments and aesthetic and protective surface treatments.Direct Metal Laser Sintering is the ideal solution for the manufacturing of small batches and final production parts with no tooling costs involved. This technology builds fully dense, almost 100%, components, from numerous alloys and metals including Steel 316L, Steel 7-4 PH, Chromo-Cobalt, Aluminium AlSi10Mg and Titanium grade 5 Ti6Al4V.

The Direct Metal Laser Sintering technology is extremely innovative and offers the opportunity to realize not only prototypes but also final metal parts, without the necessity of developing tools or moulds.

In line and with the help of the answer ofJoris Peelson this thread weve recently released an overview of allAdditive Manufacturing technologieswhich can serve as a usual reference for questions like this.

As you can see weve decided to merge DMLS and SLM solutions into one branche, as the differences are mostly patent and trademark related and dont really reflect in application differences.

SLS is most commonly used in relation to plastics (although people tend to use DMLS and Metal SLS interchangeably as well).

Terminologies in additive manufacturing are not yet properly standardized. Every industry tends to maintain its own copyrighted names. But essentially the term selective laser sintering (SLS) is applicable for polymers, plastics and non-metals. So the fusing can take place at melting or semi-melting temperatures. On the other hand, selective laser melting (SLM) is applicable for metals, where fusing takes place by complete melting of metal powders.

Industrial 3D Printing Evolves at formnext 2017

Michael Molitch-Houposted on November 22, 20175091 views

This years formnext was the largest yet, with 21,492 attendees, a 60 percent increase from last year. Formed as the result of a break from the Euromold conference, the event is just three years old and already is showcasing massive growth in additive manufacturing (AM).

formnext featured manufacturing giants the likes of GE and HP, which also demonstrated a growth in AM and the trade show. Those large manufacturers may have been two of the biggest names in attendance, but their announcements represented just a small part of what was a news-filled conference. Here, we break down some of the other noteworthy stories from formnext 2017.

Though a new company, Additive Industries has been on top of the production trend since its inception,launching its MetalFAB1 3D printerwith throughput and automation in mind. At formnext, it took this process a step further, announcing not just a new module and software for the printer, but also a partnership with the machine and plant building SMS Group to develop a production system for industrial-scale 3D printing.

The Product Removal Module is able to remove a printed part from its build plate, release any trapped powder, and then refinish the build plate with a three-axis mill. The Dynamic Laser Allocation software controls four lasers to print a single part in unison or multiple parts, using an algorithm to optimize laser allocation.

The Scale4Series being developed by Additive Industries and SMS Groups take on the factory of the future concept (also seen with GE Additive/Concept Laser and 3D Systems). The concept incorporates not just 3D printing, but every stage of the fabrication process from powder production to the delivery of the finished part.

The Scale4Series is Additive Industries version of the factory of the future, in which parts can be printed and post-processed automatically. It stands out with powder manufacturing on site. (Image courtesy of Additive Industries.)

First, powders are produced via an induction-melting and atomization process. The powder is delivered to a series of MetalFAB1 systems, which print the parts before the build plates are automatically moved to heat treatment furnaces for stress relief. The parts are then stored by a robot.

Along with the powder atomizer, multiple MetalFAB1 systems, and HIP furnaces, the Scale4Series includes CT scanners and five-axis CNC machines. The goal is to create a completely autonomous 24/7 factory.

The project will take advantage of SMS Groups expertise in manufacturing and marketing. Heat treatment, for instance, is being developed by SMS Elotherm, which will also be able to tap the automotive industry for the technology. An industrial-scale pilot system is set to go live at SMS powder production facilities by the end of the year. By 2022, Additive Industries aims to be among the top three metal 3D printer manufacturers.

Just after wrapped an interview with the aerospace manufacturer, Arconic announced a partnership with Airbus to create custom processes and parameters for 3D printing large-scale metal parts, including spars and rib structures, up to three feet in length. The technology is claimed to print parts 100 times faster than other, smaller metal printing systems. The company will also leverage its Ampliforge process, which treats 3D-printed parts using additional manufacturing technology, such as forging, to make them tougher and stronger.

This is just the latest in the partnership between Arconic and Airbus. To learn more,read our interview with Arconic.

In addition tonews of its simulation partnership, Stratasys announced the introduction of new software for its PolyJet technology, which offers unique full-color and multi-material 3D printing. Dubbed GrabCAD Voxel Print, the software is meant to provide greater control over the photopolymers within the J750 3D printer. The software is able to alter the concentration, structures and color mapping of the 3D-printed material at the voxel (3D pixel) level.

EOS brought a new polymer selective laser sintering (SLS) machine, the EOS P 500, as well as new software for its 3D printers. The EOS P 500 is designed for mass producing engineering-grade polymer parts that require melting temperatures of up to 300C. This includes strong and heat resistant polyetherketoneketone (PEKK), which it is developing with Arkema. For more on the PEKK family of plastics, read ourin-depth article.

The system features two lasers and a new recoater, and produces objects twice as quickly as the EOS P 396, which the company claims is the fastest SLS machine on the market. This is in part due to the decreased layer times, made possible by preheating the plastic ahead of printing. Additional features include a streamlined build process, a three-stage filter, data evaluation, and optical and thermal cameras.

To facilitate the use of its printers in a production setting, EOS has developed a series of software tools, including EOSPRINT for quality control and EOSCONNECT for networking machines and collecting production data. This is part of the larger EOSTATE suite for machine monitoring.

SLM Solutions stepped into the heavyweight metal 3D printing ring with the SLM 800 system, which features a massive build envelope of 500 mm x 280 mm x 850mm and four 700W lasers. The machine is designed to be scalable with a fully automated handling station, which can automate unpacking, preheating, cool down, powder removal and transfer.

The SLM 800 is smaller thanGE Additives A.T.L.A.S.and X LINE 2000R, as well as 3D Systemsnewly announced DMP 8500. Nonetheless, the new machine reflects both the larger trend of mass production in 3D printing and SLM Solutions intention to stay on top of that trend. To help in this endeavor, the company has raised about EUR60 million from international investors.

Machining and tooling equipment manufacturer Trumpf showcased the triple-laser TruPrint 5000 3D printer. The company claims that it is the fastest metal laser powder bed system on the market. In addition to increased productivity from additional lasers, the TruPrint 5000 has reduced exposure time by three times.

Trumpf has also gotten into the automation game, showcasing integrated robotics at formnext, which could move parts from the print chamber to the unpacking station.

As promised in our interview with the company earlier in 2017, Xact Metal revealed a new midsize 3D printer, the XM300. With a build volume of 254 mm x 330 mm x 330 mm, the system maintains the low-cost Xact Core technology of the startups first machine, but with a larger build volume. The price tag wont be so low-cost, however. Expected to retail at $400,000$600,000, the XM300 has a price comparable to other machines at that volume.

OR Laser also added a new machine to its fledgling lineup: the ORLAS CREATOR hybrid. The system adds three-axis milling to the original ORLAS CREATOR. This means that contours, undercuts and cooling channels are now a possibility with the system, as well as part finishing every five to 10layers.

There were plenty more announcements aside from thesetoo many to cover here. To learn about news fromHPXJet3D SystemsXYZprintingandMimaki, click the links. We also covered many of the materials unveiled at formnexthere.

The difference between EOSs DMLS – Direct Metal Laser Sintering and SLM Solutions SLM – Selective Laser Melting technology?

Budapest University of Technology and Economics

The difference between EOSs DMLS – Direct Metal Laser Sintering and SLM Solutions SLM – Selective Laser Melting technology?

I have been doing some research on the above mentioned topic, but I got a little confused.

I learned that there are several companies out there manufacturing their own AM machines (e.g. EOS, Renishaw, SLM Solutions, SLM Realizer, Cocept Laser). These metal 3D printing systems basically work on the same principle. They use a high-wattage laser or electron beam to micro-weld powdered metals and alloys to form fully functional metal components from a CAD data.

What I would like to know is how do they manipulate the beam? Do they move the laser head itself around or the laser is fixed and they use some kind of optical system to regulate the beam?

P.S.: Im told that EOSs DMLS uses mirrors to regulate the beam, whilst Renishaw moves the laser head around.

all serious laser based 3D printing machines, which need a precise focused beam like e.g. direct laser writing, use a beam stearing system like a galvanometer scanner: The laser beam is deflected by fast moving mirrors. The deflection angle theta is then transfered to a lateral displacement  e.g. x= F times theta by the focusing optics with focal length F.

Because the mirror is light and the beam has no mass such movements are very fast.

To move the laser scanner or the work piece is sometimes reasonable in addition to make larger products using the step-and-scan procedure: Most movements are done by the fast galvo scanner and some few slow movements to new positions make larger products possible.

I agree with Jens, as all the companies you mention all use laser and mirrors to guide the beam. Only Arcam uses electron beams which are guided with electromagnetics. My University has a Renishaw and it uses mirrors to guide the laser beam as the laser is stationary.

Thank you I really appreciate your help! I will definitely do more research on this topic.

As an ex-user of the Renishaws AM250 SLM, I can confirm it uses a fixed fibre modulated pulse laser and galvanometer mirrors for precise and accurate scans. Hope that helps !

Simulation von Selective Laser Melting Prozessen

Selective Laser Melting (SLM) ist ein additives Fertigungsverfahren, bei dem ein Metallpulverbett punktuell aufgeschmolzen wird. So können komplexe Geometrien hergestellt werden. Allerdings sind die vielfältigen, miteinander interagierenden physikalischen Prozesse nicht vollständig verstanden. In der Prozess-, Material- und Bauteilentwicklung sind daher zeit- und kostenintensive Experimente nötig. Die Entwicklung innovativer Simulationsverfahren aus dem Bereich der computergesttzten Ingenieurswissenschaften bietet das Potential, den Einfluss der Prozessparameter auf die Bauteileigenschaften vorherzusagen. Eine genaue Vorhersage bietet die Möglichkeit einer individualisierten Prozessplanung, sodass Bauteileigenschaften nach Bedarf lokal angepasst werden können. Der grundlegende Ablauf von SLM-Prozessen wird einleitend vorgestellt. Dem Leser wird ein berblick ber die auftretenden physikalischen Effekte bei SLM-Verfahren verschafft. Anschließend werden die thermomechanischen Gleichungen vorgestellt und grundsätzliche Aspekte der Modellierung von SLM-Prozessen diskutiert. Des Weiteren werden, ohne Anspruch auf Vollständigkeit, verschiedene existierende Simulationsansätze kurz vorgestellt.

Cost-driven build orientation and bin packing of parts in Selective Laser Melting (SLM)

br/Selective Laser Melting (SLM) is an additive manufacturing process capable of producing mixed batches of parts simultaneously within a single build. The build orientation of a part in SLM is a key process parameter, affecting the build cost, time and quality, as well as batch size. Choosing an optimal arrangement of multiple heterogeneous parts inside the SLM machine also presents a challenging irregular bin packing problem. Since the two problems are interdependent, this paper addresses the combined problem of finding an optimal build orientation and two-dimensional irregular bin packing solution of a mixed batch of parts across identical SLM machines. We address this problem specifically in the context of low-volume high-variety (LVHV) production in the aerospace sector, using total build cost as the objective function. To solve this problem, we present an Iterative Tabu Search Procedure (ITSP), which consists of six distinct stages. We test each stage in the ITSP on 27 manually generated instances, based on 68 unique geometries ranging in convexity and size, including six real-life components from the aerospace industry. Two of the six stages, which are driven by support structure volume, returned the highest improvement in cost. Overall, the results showed an average cost improvement of 16.2\% over the initial solution. The initial solution of the procedure was benchmarked against a commercial software, showing comparable results. br/
