the future of3D printingcould see color-changing technology transform our wardrobes.at least with the work of MITs computer science and artificial intelligence lab who are introducing a new kind of 3D printable ink that makes it possible to recolor 3D objects after they have been printed. the process, known as colorfab, works by using base dyes and light-adaptable or photochromic dyes which appear only when exposed to UV light.

the method, developed by lead computer scientist stefanie mueller at MITsCSAIL, combines a 3D printing interface where users can create the object they want along with a layer of  the color-changing ink.by using the colorfab interface, individuals can then select areas of the object to revolor before activating them with UV light.

colorfab improves on previous formulas of photochromic inks which could only activate one color and only when exposed to UV light.muellers method involves painting a dense multi-color pattern onto objects and then selectively activating or deactivating certain colors with light. the ink can also hold its color after the light source is switched off.

the colorfab system is designed specifically to work with the precision of 3D printers, where photochromic inks have not been used before.as explained in this paper, once the method has been refined, the technology could be developed for use in the garment industry eventually helping to cut down on the waste we produce by creating various options in only one product.

12 amazing 3D printed objects

3D printing, or additive manufacturing, is where a 3D object is printed from a digital model. The 3D printer extrudes materials out of a nozzle, building objects layer by layer according to the instructions from the digital file.

3D printing has been used to make manufacturing prototypes for decades, but the technology has only recently become available for consumers to use themselves. The technology still has itslimitationsbut its only a matter of time until this technology advances and dominates our manufacturing systems. 3D printing can also be a powerful tool for designers, who can create prototypes and mockups to pitch ideas to clients.

Weve rounded up 12 amazing 3D printed objects that show just how powerful this technology can be:

These printed snacks are made of ground-up meal worms, yum!

These Meal Cubes were printed on a 3D printer that combines powdered proteins, carbohydrates and sugars to create edible food products. The printer is being developed by Systems & Materials Research Corp to address world hunger and improve our unsustainable food systems by using this more efficient and economical way of producing food. Their argument is if food is made from nutritionally balanced powders, then we could get the same nutrients from a wider range of sources, such as ground-up insects, algae or grass. The printer can also be programmed to print personalized meals depending on the exact nutrients that a particular person needs.

The most important utilization of this technology.

Now this is something I would invest in. This 3D chocolate printer heats up the chocolate in the cartridge and squirts out layer after layer of chocolate after you upload your own design file to the machine!The Choc Creatoris the first commercial chocolate printer and was invented by a team of researchers at the University of Exeter. This miracle machine fromChoc Edgeretails for a mere $4,384.56!

3D printing is going to be huge in the medical field.

This custom prosthetic was printed from titanium powder with a lightweight porous structure, like real bones. The patient who needed it was able to talk normally with this new jaw minutes after waking up from surgery. 3D printing is going to be huge in the medical field, where individualized parts can be printed based on scans of patients bodies.

This plastic gun has been named the Liberator by its creator.

This is the worlds first working 3D printed gun. Its made almost entirely of plastic and has successfully fired a .380 caliber bullet. It was developed by Cody Wilson, a law school student who runs the organization Defence Distributed, that aims to make gun blueprints available online for anyone to download and print. The U.S. State Department has already forced Defense Distributed to take down the blueprints fromDefcad, however allegedly more than 100,000 of the plans were downloaded before the crackdown. The good news is real guns are still cheaper and easier to obtain than printed guns. However as the costs of 3D printing go down, the more worried we should be.

Now you can actually print the face only a mother could love and give her the perfect present!

Artist Heather Dewey-Hagborg took samples of peoples DNA from gum, hair and cigarette butts left in public places, and created 3D portraits based on their genetic makeup. The printed result isnt an exact copy of the real persons face, but its a pretty cool (and creepy) way of combining art and science.

Thisdrafty-looking dress is made ofa lightweight, flexible material.

Modeled by Burlesque dancer Dita Von Teese, this nylon dress was printed byShapewaysand designed on an iPad byMichael Schmidt and Frances Bitoni. Its made up of thousands of components that were printed to fit her body exactly, and based on the Fibonacci sequences of numbers.

Try throwing this one on a pottery wheel!

This delicate vase is available for purchase on Shapeways and was designed by user virtox. Its produced with a fine ceramic powder, fused together with a binding agent, fired and finished with a glaze. Its food-safe and available in several finishes including Avocado Green Glossy and Eggshell Blue Glossy!

Cant wait to meet your child? Print them out in utero!

A Japanese service called Shape of an Angel will print a 3D model of your unborn fetus, using a technology called BioTexture, which processes image data from MRI and CT scans for 3D modeling. Expectant mothers have been shelling out the cash for this hot new product, which starts at $1,275 per figure, and goes up depending if you want to get the result made into keychains or cellphone dongles. This consumer product may seem a little strange, however its potentially a very powerful tool for vision-impaired parents, and for doctors to study potential malformations in developing fetuses.

This is a great first project for designers who are starting to learn CAD.

This custom iPhone case design was inspired by Indian patterns such as Mandalas. Its available for purchase and was designed by user Genghis. Its printed in a strong and flexible plastic and starts at $18.22.

Forget metal-smithing! Now designers can simply print their bling.

This intricate bracelet is also available for sale at Shapeways, and designed by user nervoussystem. It can be printed in plastic and stainless steel, and is a top seller on Shapeways.

Even Michelangelo couldnt carve this out of a block of marble.

This incredibly detailed sculpture by artistKevin Mackwould be difficult and time-consuming to produce without 3D printing. According to Mack, this sculpture represents a physical manifestation of the flow of consciousness in a transhuman entity.

For this 3D figurine, we chose to create Community Director Jason Aiken (in his fist tee).

This little guy look familiar? He bears a striking resemblance to our very own Community Director Jason Aiken, and hes even wearing the exclusive 99designs fist T-shirt! We used an online application calledMixeeMeto create this customized figurine. They partner with Shapeways, and their online customization app lets you pick and choose facial features, hair color and upload designs to print on their clothing.

These amazing printed objects are redefining the manufacturing process, but many are made on industrial-grade printers that are not as accessible and affordable for the average consumer. For designers, 3D printing is better used as a tool than an end product. Theyre great for making inexpensive prototypes of product designs to pitch to clients before they invest in expensive manufacturing processes and supplies.

From digital file to physical object. This model was created in the program MeshLab.

Clients are super responsive to seeing print designs like business cards photoshopped into mock-ups, the same thing is true for 3D printed prototypes. Some designers actually use 3D printed characters to pitch company mascot designs to clients by giving them a maquette they can hold in their hands.

If youve ever wanted to do product design but were limited by your lack of manufacturing knowledge, heres your chance to start making your ideas reality!The technology is only going to advance, so why not start learning the basics now? Heres a few resources to get started:

SketchUp is very user friendly and it can create 3D printer-ready .STL files.

Google SketchUp: This free CAD program is extremely basic, but it is very easy to learn for beginners. If youre serious about making professional, finished products with this technology, youll want to learn more advanced programs likeSolidWorksandRhino 3D, both of which are a little pricey but have a pretty sweet trial programs you can download from their websites.

Ideally, you should go to your local 3D printer shop to see your designs getting printed and learn firsthand how to design according to the specifications of the printer. But if thats not the case, youve got a co
uple of options: buy a consumer 3D printer or send your design files to a 3D printing company to print.

Additive manufacturing is more efficient and less wasteful than traditional subtractive manufacturing, and its only going to get cheaper. The ultimate goal of 3D printing would be to manufacture all consumer products in the location of their purchase, on demand and on the spot, which would eliminate shipping costs and wasting unsold products. In the future, the possibilities for 3D printing will be limitless.

7 Strange 3D Printed Objects from Organs to Bikinis

Its not inaccurate to refer to 3D printing as a sort of new age industrial revolution. Never before have we been equipped with such a capacity to create; never before has the manufacturing process been so decentralized as it is today. The 3D printer could well be a revolutionary invention, and if the technology is further developed, it might well put many industries out of business. But thats for the future.

As you all well know, whenever some new technology surfaces that allows people to create, theres invariably going to be a group that uses it forless than orthodox purposes. 3D printing is no exception. Even though the technology is still in its infancy, people have already used 3D printers to create some weird stuff, from mugshots printed using DNA to sculptures of unborn fetuses. Today, were going to look at some of the strange 3D printed objects from around the connected world.

This 3D printer uses nutritious ingredients to print food while you wait. TheFoodiniis a 3D printer by Natural Machines that creates a variety of meals at your direction. How it works is actually pretty simple: you select any of a number of pre-prepared, fresh ingredients, then load them into the printer. Once youve selected the meal you want to prepare, itll arrange everything for you with absolutely no fuss. In short, youll be able to make restaurant-quality meals (or at least meals that look like theyre restaurant quality) with little to no effort. Sweet, right?

Say hello to the N12, the first article of clothing in the world created entirely with a 3D printer. From what the creators have said on their site, they hope that this will be the first of many products like it. The design itself is actually quite impressive, displaying an intricacy rarely seen in clothing. Plus and Id imagine this is the most important part its apparently quite a comfortable wear, as well.  Affordable, too. You can buy one yourself (along with a small selection of other strange 3D printed objects and accessories)here.

Me, Im excited for when they start printing shirts pants. I feel like the ability to make ones own clothes might throw a spanner in the works for the clothing industry, no?

There are strange 3D printed objects, and then theres this.MakerLoveis a website that exists on the principle that people will choose to make certain items they might only wish to do privately. The site provides a wide variety of sex toys which can be printed with a 3D printer. Particularly enterprising users can even submit their own designs to a design contest on the site. Like a Sigmund Freud shaped sex toy? I guess somebody out there thought itd be a good idea.

In the future, there may no longer be construction crews. At least not as we know them today, anyway. Thats because assuming researchers at the Institute for Advanced Architecture of Catalonia get their way cities of the future will be constructed by a team of robots calledMinibuilders, which will craft them from the ground-up. This robotic swarm will be able to construct buildings of any size, with a level of efficiency human construction teams can only dream of. Even better, they suffer from none of the pitfalls commonly associated with 3D printing (such as having to build a printer large enough to accommodate the entire structure; a problem they ran into in China). What this basically means is that well be able to erect cities almost as quickly as we can design them.

Theres more to 3D printed food than what we can prepare at home.Modern Meadowis a startup funded by billionaire investor Peter Thiel, and it deals in a very peculiar product: 3D printed meat and leather. It bills this bioprinted meat as an environmentally friendly means of enjoying animal protein; one which cuts out a big chunk of the process involved in  meat and leather production. According to Modern Meadow co-founder Andras Forgacs, the process by which we currently prepare our meat is a horrendously wasteful one, and an environmental train wreck. They hope that their synthetic meat-printing process which has already managed to build three-dimensional tissues and organ structures can cut down on the excess waste, and save a few lives in the process.

Organovofollows a similar principle to Modern Meadow. The difference is that while the latter uses the technology to create environmentally-conscientious hamburger alternatives, Organovo is creating full-fledged human body parts. Yes, you read that right this organization is basically printing livinghuman tissue. Currently, the technology can produce tissues of about twenty or so cell layers thick, comprised of multiple cell types. Already, theyve created a functioning human liver; theres no telling what else might come of this technology. Pretty soon, we might even be able to replace lost limbs and organs.

One of the best things about 3D printing is that it allows a nearly unprecedented level of freedom when it comes to designing a product. The user can literally make something exactly the way they want it with absolutely no fuss. TheSmartboardis indicative of this trend. Its basically a surfboard, printed from the ground up for an individual surfer. Every single aspect of the board is customizable, from the stiffness to the size to the shape. It is quite literally an extension of the surfer who uses it and thats exactly as it should be. Now weve just gotta wait for all the other 3D printed products that are bound to follow I dont doubt therell be some good ones, for sure.

These 3D-Printed Objects Can Turn Any Color You Want

MIT researchers hope a process that uses a special photochromic dye to change an objects color in response to light will one day reduce waste

A printed ring through the color-change process

Imagine youre in IKEA, looking for a plastic kitchen stool. You find one, butdarnits turquoise, which just doesnt match your home color scheme. No problem. You tell a salesperson, who pushes a button andbingo!the chair changes color to the exact lavender of your KitchenAid mixer.

This sci-fi scenario is several steps closer to reality now, thanks to new research from MITs Computer Science and Artificial Intelligence Laboratory (CSAIL). Researchers at the lab have developed a method of changing the color of a 3D-printed objectafterthe objects been printed.

The plastic objects are printed using a special ink that changes color in response to light. UV light activates the colors you want, while visible light deactivates the ones you dont. Users control the process pixel by pixel through a digital interface. The color changing takes about 23 minutes.

The process, which the team calls ColorFab, was described in a recent paper, to be presented at theACM CHI Conference on Human Factors in Computing Systemsin Montreal this April.

We use a UV light to change the pixels on an object from transparent to colored, and then a regular office projector to turn them from colored to transparent, explains Stefanie Mueller, senior author and professor at CSAIL.

Since there werent any 3D printable photochromic inks in existence, CSAIL had to create its own. The ink has three parts: a base dye, a photo-initiator, and light-adaptable or photochromic dyes. The photochromic dyes activate the colors in the base dye, which is then hardened by the photo-initiator.

We were surprised that we were able to develop our own custom ink that was able to perform as well as it did at recoloring, Mueller says.

While systems for changing objects colors existfor example, Japanese researchers created a photochromic carpet that allowed users wearing UV lights on the soles of their shoes to create colored footprints on a carpet dyed with color-changing inkthese have all been single-color. Color-change processes relying on thermochromic (heat sensitive) ink exist too,but they are also single-color. Some of the same researchers behind the photochromic carpet did create amulti-color change systemusing painted photochromic pixels, but it was only used on paper, not on 3D objects.

Mueller imagines the ColorFab technology being used in advertising, allowing companies to print billboards and then adjust them to match the surrounding color schemes of the spaces where theyre installed. It could also allow users to customize products in real-time.

For example, stores could re-coloran article of clothing or accessory so that a shopper can see if they like it better in that shade, Mueller says.

In theory, the technique could help reduce waste by making it unnecessary to buy multiple versions of items. Instead of having bracelets in every color of the rainbow, you could simply program the one you have to match your current outfit. Instead of keeping several sets of kitchenware to go with different dinner themes, you could set your plates to turn bright yellow to contrast with your signature ratatouille.

The team says they hope to bring the process to well under the current 23 minutes by using stronger lights or more light-adaptable dyes, and to make the colors sharper. They also eventually hope to expand the technique to materials beyond plastic.

As for the time frame? Muellers not sure when color-change products might be headed to your local superstore. So think hard about that neon green tea kettle before you buy.

Coloring Complex 3D Printed Objects

A new inexpensive technique for coloring complex 3D objects may mean more realistic prototypes for design engineers and more end products made by additive manufacturing.getmedia/ff492dcb-012b-4a40-9ffb-38ef64bc186e/Coloring-Complex-3D-Printed-Objects_thumb.jpg.aspx?width=60&height=60&ext=.jpg

A new technique for coloring complex 3D printed objects developed by researchers at Columbia University and a Chinese university could make possible more realistic prototypes as well as more end products made by additive manufacturing.

Until now, it has been difficult to produce complicated color patterns and a variety of colors for 3D manufactured items at low cost because of limitations of hydrographic printing, or water transfer printing. The process is widely used in industry manufacturing processes for quickly coloring and applying repeatable color patterns to surfaces of objects such as iPhone cases.

As a design engineer, the challenge related to3D printingis you are often making models and prototypes one object and you want the ability to customize color, saysChangxi Zheng, assistant professor of computer science at Columbia and lead researcher on the project.

Although hydrographic printing can produce high-quality coloring and can be used on a wide range of materials, it cannot precisely align patterns on complex surfaces and color choices are limited. Zheng explains, If you have a piggy bank and want to color some black dots, for eyes and nose, its very hard to do. The dots for the eyes and nose could end up in a completely different spot than desired.

There are many times when a user would like to color the surface of an object with particular color patterns, to decorate a 3D-printed mug with specific, personalized images or just to color a toy, he says.

It just doesnt work becausehydrographic printinginvolves using a film featuring the desired design that is softened with chemicals in water. The film is then wrapped around the object and clings to its surface. But since it gets stretched in the immersion process, alignment on the object is not precise. You have no control over the film, and it gets distorted, Zheng says.

Additionally, colors are limited except with high-end printers, and even that is very expensive. With Zhengs new method, any colors are possible as are intricate patterns, inexpensive enough to be done with3D printersmany individuals are now purchasing for themselves. This system is easy to set up for personal use and its quite inexpensive, less than 40 cents per printing, Zheng said.

Since announcing the work, Zheng says he has heard from companies interested in coloring everything from a motorcycle helmet to car accessories to Halloween masks.

The system includes building a physical hydrographic system with off-the-shelf hardware, integrating virtual simulation, calibrating the object calibration, and controlled immersion.

He and his team developed a new computational method that simulates the stretching that occurs during immersion and predicts the distortion. Once the distortion and the desired pattern have been simulated, a colored film transfer is generated that takes into consideration the distortion and aligns exactly with the surface textures of the object.

Their work has also included developing a 3D vision system that measures the objects orientation and dipping location. For very complex objects and designs, multiple immersions using different orientations of the object are possible and may be required.

The entire system is built upon off-the-shelf hardware and can be easily set up by ordinary users, the researchers wrote in their paper. The object is held by a mechanical gripper connected at one end of a vertical aluminum rod, driven by a linear DC motor. Underneath the rod is a container of water. The location and orientation of the object is measured. The teams computational model predicts the stretch and distortion of the color film and creates a map between the locations on the film and the surface locations to which they are to be transferred. With that map, a color image can be printed on the film that takes into account the film distortion.

Zheng became interested when he saw a demonstration of hydrographic printing showing very complicated patterns onYouTube. He soon learned that in China, kits for hydrographic printing are available for sale toDIYers, and thought, How can we improve this?, he says. That led to a collaboration with researchers at Zhejiang University, one of Chinas oldest and most prestigious institutions, in Hangzhou.

Zheng is very interested in the interaction between the virtual world and the real world. This research is a good example of how virtual-world computation can work hand-in-hand with a real-world manufacturing process and significantly improve the production quality, he says.

How to Finish 3D Printed PLA Objects

Here are a some methods I use to put together 3D printed PLA parts and a couple of ways to finish 3D printed parts.

The best way to put3D printed parts together, if you have a 3D printer that has a small build platform, is to break the STL file into smaller parts using a software likenetfabband then use a 3D printing pen to put the individual 3D printed part together. The 3D printing pen I use is from3D Simowhich you can use with various types of filament ing a 3D printing pen in combination with a rotary tool like theDremeland plain old Sand paper is a much superior way, then just using glue. Obviously you need have a good amount of patience ! as this time taking process..

As part of thefinishing process, depending on how you want your 3D printed object to look and feel you can use one of the methods shown in the videos below

Use Z Poxy in a scenario, when you want your part to look glossy and have shinny metallic finish to it. And retain the color of the filament you 3D printed your part in. This is idea if you want to finish a small figurine you printed.

This is much faster and cheaper way to finishing larger 3D printed parts, and yes ! you will need to apply multiple coats to get a nice even finish. In addition, painters touch comes in number of colors , which mean you can print your parts in white PLA and then spray paint them in your favorite color.

As part of the finishing process, I have mentioned sometipsbased on my experience. And please leave a comment/suggestion below if you use one of these methods and I will add it to the list..

You can also use these methods on ABS , but the best way to finish ABS parts is to use the Acetone vapor technique ..

Here are the STL files if you are interested in following along or just want to make a copy of the planter (most of these files are from an earlier instructable I wrote calledDarth Vader Planter)

Download the STL files attached and using 3D printing software slice and 3D print the files.

Here are suggested slicer setting for all STL files

Printing all the parts individually should take about 6-7 hours and is dependent on your 3D printer settings.

To demo the 2 finishing process , I printed the STLs in black Hatchbox PLA and white PLA.

Now to put the part together instead of using super glue, we are going to use a 3D printing pen , which means you will need a few tools –

3D printing pen – I am using the one by3D Simo, but you can by one from Amazon

PLA filament from the same spool you used to originally to 3D print the part

Once you have your parts printed , use the Rotary tool/sand paper to file the edges of the parts to put together.

Use a hot glue gun to put the parts together ,this will temporarily hold the part in place,and will make it easier to use 3D printing pen to melt PLA on the inside of the part.

Now once the inside of your part is done, remove the hot glue using an xacto knife from the outside as shown in the picture above, and extrude out filament from the Pen to apply to the outside of the part.

Using this method can test your patience!! , so remember take breaks.

In addition, remember to do this in a well ventilated area and wear protective glasses to cover your eyes while sanding.

Now comes the hard part , Sanding !!

Use a rotary tool like Dremel to speed up the sanding process and they use sand paper.

Wash the part once you done , you will see sand marks on you 3D printed part as shown above, but that should not be a problem as you are going to finish it with one of the steps mentioned below.

Since you have used a 3D printing pen with the same filament you printed STL files with , this method will prevent the parts from coming apart in a few month , when compared to if you had used glue..

As part of theZ poxy kitit comes with two bottles, on contains the resin and the other the hardener.

Approximately pour equal quantities of the resin and hardener in a container.

Mix it using the end of a brush or one of your test prints, this takes about 3-4 mins and wait till the liquid turns a whitish color.

Use a combination of small and large paint brushes to pain the model, start with the part of the 3D print which has more details , like the eyes and the mouth of the Darth Vader Planter.

Let the part to dry for at-least 4 hours and keep it away from dust.The time 4 hour can vary, and depends upon the portions of hardener and resin . Here the safest bet is to leave the part overnight to dry.

Do not lift the part up before the part is completely dries , or else you will end up leaving your finger prints on the model.

If you dont have Z Poxy available , you can also try outXTC-3D buy a company called Smooth-On.

Tips for applying Z Poxy to the 3D printed part

Buy the Z Poxy which say 30 mins on it, so that you have more time to work with the solution before it gets hard.

If you are applying this to a small figurines, you may want to hot glue the base of the 3D printed part to piece of wood, so that using the brush is much easier and you dont leave finger prints/glove marks on the model.

In addition, try and place you model on a base that you can move around like a box or a piece of wood , if you dont have one of them fancy turn tables.

Try and use a transparent tupperware container so that you can see the mixture turn a cloudy white color.

Do this in a well ventilated area , though it say it is odorless on the box, it has a slight pungent smell to it

Use gloves, as this solution can stick to hands just like super glue and can be difficult to get off.

Try and keep you model at a room temperature,in about 15-30 C and away from dust.

What type of 3D parts are ideal to use Z Poxy on.

Dual printed part as shown in the picture above

Temporarily water proof a part, this makes the surface of your print so smooth that the water just drips off.

do NOT use this with moving parts like gears mechanism or part that your use to prototype a robot, because once your done this leave a soft coat of 1-2mm on your part.

do NOT using this method on extra large part, in my case with the Darth Vader planter in the picture above I would have preferred using the method detailed in the next step as this is a much more expensive option.

Compared the previous method this is a much cheaper as one of these bottles can cost about 6-8 dollars and can be easily found at your home hardware store (like theHome Depot) , the brand that I am using is called Painters Touch 2X by a company called Rust-oleum.

This is an ideal method to use with extra large 3D printed parts , and unlike the previous method these spray bottles make it easy and the process more gratifying. In addition the access paint just drips of the part, so place your part on a smaller object, like in the picture above.

Spay the parts as shown it the picture above, I applied about 4 thin coats over a period of 2 days.

If you want to maintain the color of you PLA print use the Gloss clear version, for pictures check out the instructable at –

In addition, I have found that spraying a primer really does not help.

Like any other spray paint, use the can in the well ventilated area

Test a spray on a failed part to get a hang of it , if you are using a spray paint for the first time

Do more thin layer then just a couple thick layer.

Wipe of the tip after use to prevent clogs when you use the can again

Between your coats ensure that your earlier coat is completely dry ,I found that it takes the first coat at-least 5 hours to complete dry

Protect your eyes by using protective gear and a safety mask around your nose.

Depending on your 3D printed part , spray the under side part first

Use a side to side motion for a smoother finish and better coverage

Shake the paint can every couple of mins while using

Hold the spray can about 20 cms from the 3D print.

What type of 3D parts are ideal to use with Painter Touch

Use this method with large parts with thicker wall like the planter in the picture above, you may want to adjust your 3D software slicer

Do NOT use this on moving part like gears, but you can use this on robotic project , but ensure that your parts are thick enough (at-least 6 mm thick) , otherwise you will observer that the part becomes flexible and will deform from its original shape after a couple of coats

Works ideal with part in combination with wood and other metal object, say you are putting an old table together and kind find the correct brackets and you have to 3D print the brackets

Temporarily water proof your part when your print is large with a lot of infill, in this case the previous method will work better

Please be positive and constructive.

I love this planter. Could it be printed as a complete model on a ultimaker 2? If so do you have the STL for the complete model please instead of it in pieces. I would very much appreciate it. Thank you in advance

Carmelito, This is a very well document. We brought a 3D printer and my son wants to print this and gift it to my husband for Fathers day. It will be a very masculine planter perfect for his office. Thanks for the idea and all the files

Very good Instructable! I plan to print parts today for use as masters for molding using silicone rubber molds. Do you think the epoxy technique would work well and allow the silicone to release?

Thanks for your comment , I currently have no experience with Silicone rubber molding.The ZPoxy make the surface really smooth so i think it should help, but i am not sure if the Silicone/catalyst will react the ZPoxy, Or if Zpoxy will act as a good release agent.. Please post an update if you get to trying this out..But, if you are planing to use a simple method like using Silicone Plastique, i think the application of Zpoxy should help..

it should be noted that you can paint the PLA item before you apply either finish. also you can use matte clear coating if you dont want the glossy finish and still would like a painted design or dry brushing to show through.

you should add a mold release on the outside beforehand.

3D Printed House 10

3D Printed House 1.0 (3D 1.0) is a case study in 3D printing major components of a 3D printed house for the Jin Hai Lake Resort Beijing. The house demonstrates an integration between traditional construction methods and 3D printed manufacturing. Whereas most visions for a 3D printed house demand a very large 3D printer, The 3D Printed House 1.0 considers the use of a 3D printer farm that employs a battery of 3D printers to print building components, 3D printed bricks and tiles, using renewable and innovative materials, such as salt and a unique cement polymer. It also highlights as objects the rooms that contain the public and private spaces within the house.

Inside, the private spaces of the housethe bedrooms, bathrooms and family dining room are housed in translucent 3D printed double hieght and two story tall vessels constructed of3D printable salt polymerbased onThe Saltygloo.

The interior of the salt volumes capture light from skylights above, creating a series of glowing translucent rooms within the concrete box.

The vessels serve as objects that define spaces within the larger volume, as well as contain intimate spaces within.

Outside, adjacent to the pool, is a free standing 3D printed pool cabana, also in salt polymer, to heighten the tension between the water and the spaces of salt.

The exterior cladding of 3D Printed House 1.0 will be constructed 3D printed using a special3D printed fiber reinforced cement polymer, developed by Emerging Objectsutilizing ourPicoroco Block. The variegated pattern allows for views and light to pass through in some areas of the wall, but not in others. The quality of light and shadow constantly changes across the surface with the passing of the day. Major structural components of the house will be comprised of cast in place concrete, plastered white.

The interior of the 3D printed facade wall reveals the bumpy surfaces underlying geometrya series of interconnected pentagons, hexagons and quadrilateral shapes whose terminus is a circle.

Translucency, porosity and openness are all tested in the different material conditions and inform the optics, lighting, views and thresholds between adjacent spaces.

Prototypes of the 3D printed salt rooms were constructed at full scale to demonstrate the potential of 3D printed architecture.

How engineering became an attractive career for young graduates

A team of engineers has found a way to edit 3D-printed objects after completion.

While 3D-printed objects promise a major revolution in manufacturing particularly in future deep-space exploration there is still one outstanding issue: you cant make changes to it once the object has been printed.

But not any more, according to a team of researchers from MIT who have found a way of repeatedly changing the colours of 3D-printed objects after fabrication.

Called ColorFab,the methodinvolves using a specially created 3D-printable ink that changes colour when exposed to UV light, meaning the object can be recoloured in a little over 20 minutes.

As the team improves upon this creation, they expect that this timeframe could shrink substantially.

Unlike previous attempts to change 3D-printed objects colours using single-colour systems, ColorFab developed a simple hardware/software workflow whereby the user uploads their model, picks their desired colour patterns and then prints their fully coloured object.

To change the colour, the method uses a UV light to change the pixels on an object from transparent to coloured, and a regular office projector to turn them from coloured to transparent.

The custom ink is made of a base dye, a photo-initiator and light-adaptable dyes. The light-adaptable or photochromic dyes bring out the colour in the base dye, and the photo-initiator lets the base dye harden during 3D printing.

When the printed object is placed on the platform, it is then just a matter of choosing what colour you want to change it to.

Aside from trying to speed up the colouring process using a more powerful light or light-adaptable dye, the team hopes to make the colours appear less grainy. This could be achieved by activating colours closer together on an object, and so using blue and red to create purple, for example.

This is the first 3D-printable photochromic system that has a complete printing and recolouring process thats relatively easy for users, said the papers co-author Parinya Punpongsanon.

Its a big step for 3D printing to be able to dynamically update the printed object after fabrication in a cost-effective manner.

Commercially, the breakthrough could allow you to change the colour of your smartphone case depending on your mood, or for stores to show a customer what a product might look like in a different colour in real-time.
