Cooking & molding bioplastics at home: recipes, results & tips

nospam@example.com (Joris Peels) — Mon, 15 Feb 2010 11:10:00 +0000

Inspired by Mendel Heit, Martin Bauer and Jay Cousins we've been doing a lot of playing around with bioplastics. Here you can see the original post with a video that shows you how they made bioplastic. Additionally this video is quite helpful.

So why have I been spending every minute of my free time cooking bioplastic? Basically the idea is: make a biodegradable plastic in your own home. This will potentially be of big benefit for desktop 3D printing, personal production and also in reducing fossil fuel consumption and one's carbon footprint. Make a material with easily obtainable biological products that you can in turn use to make lots of things. If we're dreaming we can also then perhaps make a material that enables you the consumer to recycle the consumer products you make in your own home at home. I tried to test and replicate a number of recipes and also show you what results you can achieve by cooking bioplastics in the home, right now.

A free STL viewer for your Iphone by Netfabb

nospam@example.com (Joris Peels) — Fri, 12 Feb 2010 11:40:00 +0000

So lets say you're on the move and get a tweet from a friend that they've just added something to Thingyverse. Or someone tells you that this one spur gear right for your project can be downloaded from the Shapeways 3D parts database, only you're walking around. What do you do? Well from now on you can download the Netfabb STL viewer on your Iphone. It is free. You can point it at a URL and it will download the STL and let you see it while you are out and about. Using the Iphone's touch pad you can spin and rotate your models while looking at them from all sides. You can pinch to zoom in and I think its generally more intuitive to use than a PC STL viewer. Check out the video of this fun free tool below or download it on the App Store.

Shapeways interviews Bruce Sterling

nospam@example.com (Joris Peels) — Fri, 05 Feb 2010 09:19:00 +0000

Bruce Sterling is a noted sci fi author, futurologist & speaker. As well as being an award winning author and one of the founders of the cyberpunk movement he is an early and constant booster of Augmented Reality technology and coined the word Spime. Spimes are pieces of technology that know where they are and can reveal their entire history to you. He is also behind a project that hopes to document dead media, founded a green design movement, loves Bollywood movies, is a hacker in the original sense and you really should read his Wired blog Beyond the Beyond.

Joris Peels: I was wondering if at one point you would be interested in doing an interview about 3D printing/the future?

Bruce Sterling: Well, man, all I can tell you is that I'm hanging out at a monster science event with labs-on-a-chip and 3d biofactories.

Joris Peels: Sounds good, are there any jet packs?

Bruce Sterling: Only for the microbes.

laser cutting bioplastics

nospam@example.com (Joris Peels) — Thu, 04 Feb 2010 21:27:00 +0000

This video is awesome. You can make your own bioplastic. Starch, glycerine, vinegar and water. 7 parts water, 1 vinegar, .5 glycerine and 1.5 parts starch. You heat the mixture up while stirring. You can then flatten it and it will turn into a sheet of bioplastic. You can even add your own colors to it. The sheet can then be laser cut. You can make plastic and then laser cut it. Wow? I've been watching this video for 20 minutes now over and over again. Guess what I'll be doing this weekend? More than a little fascinated. Thank you Lasern!

Shapeways interviews Andrew Plumb aka Clothbot

nospam@example.com (Joris Peels) — Tue, 02 Feb 2010 15:29:00 +0000

Shapeways Community Member Andrew Plumb is also known as Clothbot. He is doing some pretty amazing things with wearable electronics, integrating fabrics and robotics, with his Makerbot and on Shapeways. You can check out his site here or follow him on twitter here.

Joris Peels: What is a clothbot?

Andrew Plumb: Short answer: A cyborg teddy bear! (Cue the Akira nightmares.) Longer answer: A robot needs to play well with its surroundings. In a household or office space that means bumping into things and people, surviving frequent encounters with fluidic space, etc. The real world is messy. I could spend my time waterproofing a standard tin-can robot, hammering out dents, adding proximity sensors and patching holes in the walls, or I could take a different approach. Clothbot is about robotic or cybernetic elements integrated comfortably into our surroundings and on our person. Making conventional printed circuit boards (PCB) is messy, requires toxic materials to fabricate, and the end product is quite rigid. When your "board" is a piece of cloth and electrical conductor is thread, you don't even need molten solder to connect elements into a useful piece of active circuitry. Power up the computerized embroidery machine (I don't have one yet) and you have a tool to build flexible, multilayered designs in no time!

Joris Peels: Tell us about your wearable disk buttons design.

Andrew Plumb: In the beginning, Bre Pettis needed a button so he makerbotted one. I asked myself, how do you make a great idea like Makerbot-printable clothing buttons better? Why, make them Lego Compatible! To encourage others to explore the mashup potential I made the design source available under a simple Creative Commons - By license.

Now, a Makerbot is great for printing out fabricated objects (I call them fabjects) near the size of a cupcake, hence the product name Cupcake CNC. However, as the design dimensions approach the 0.5mm diameter aperture of the extruder nozzle, the resulting fabjects get rough. My MakerBot prototype gave me enough confidence in the soundness of my basic design to place that first order with Shapeways.

Getting back to the clothbot idea, I could have used press-fasteners to add, remove and reposition parts but they tend to be bulky and short each other out if you don't back them with something more rigid. I could have used more conventional PCB sockets, which would work but would look out-of-place in every-day wear. Turning a button into a socket or touch-sensor hides the function until it's needed pretty well and allows for more whimsy in the design without resorting to spinning bow ties.

Joris Peels: Tell us about your soft circuits.

Andrew Plumb: I've dabbled with soft circuits (like those Mouna's electroniccrafts.org page) on and off for years but it's only in the last year that I've really focused on pulling it all together. Ideas are easy; implementation takes discipline.

Joris Peels: Why are you so fascinated by organic things & technology?

Andrew Plumb: On one hand, technology is what I do for work and play. I'm an electrical engineer by trade, helping my co-workers design integrated circuits (ICs). On the other hand, natural organisms adapt to their surroundings by way of simple pressures of competition, cooperation and environment. Organic technologies are those that integrate well into our tech-augmented lives. Sharp edges are confrontational; edgeless surfaces rock and roll with the flow. Sometimes you need confrontation - try trimming your nails without sharp edges - but for the most part you want comfort at your finger-tips and on your person.

You've been involved with wearables for a long time...whats a wearable?

To me, wearables computing, electronics, mechatronics are about mind- and body-enhancing technologies that meet us half-way between automating our tedious routines and amplifying our life experiences. It's a bit of a paradox really, a blend of those technologies that disappear into the background (taking pictures, recording sounds for future review, GPS coordinates, simple biometrics) and those that immerse you in a fully augmented reality (hands-free headsets, head-mount optics filtering and amplifying your vision, reactive clothing, exoskeletal robotics, real-time translation). Striking the right balance at the right time is a challenge.

What is the dream of wearables?

I'm not sure... I've amassed quite a collection of head-mount displays, data gloves, embedded computers and chording keyboards over the years chasing dreams, but I have integrated very few of them into my every-day activities. I don't like being anchored to a desk, but there are times when I find myself spread across two or three monitors deeply immersed in data for hours. The simple augmented reality apps that are starting to appear on iPhone and similar platforms offer hints at what's possible, but it still feels like peaking through keyholes. Virtual Reality (VR) systems from fifteen years ago felt more immersive because your hands were free and head directly tracked. Over the years I've drifted to a more general pervasive, ambient computing approach. ...Ask me again in another five years. :-)

How do you like your Makerbot?

Loving it! I had been tracking Fab@Home and RepRap projects for a while but the barriers to entry (sourcing materials, tools and availability of my time) were such that I didn't jump into them right from the start. When MakerBot Industries appeared with all the pieces in a convenient kit form, I pounced and landed up with MakerBot Number Nine (see http://clothbot.com/wiki/MakerBotNumberNine) from the first batch. It's been particularly fun being involved in bootstrapping the community from the beginning. As each new batch has come online the former-newbies have been pitching in answers to the more common FAQs and taking on wiki editing roles, leaving those of us early-batchers with more time to take deep dives into the larger set of reprap development activities. In the larger ecosystem of rapid prototyping technologies, I think of my Cupcake as a "bone maker". It's great for prototyping ideas and making the scaffolding around which to wrap skins with more finish. Being able to take a design from drawing to prototype in less than a day is awesome! When the raw material costs are so low though, being able to tweak and reprint a design ad infinitum can be a bit of a curse. It takes time to learn when good is good enough. Using Shapeways has helped impose some discipline on my own design process.

What is Shapeways doing right? What are we doing wrong?

The Right? Simply put, the breadth of fabrication technologies you carry. You provide us individuals with access to manufacturing processes normally reserved for large institutions and people with deep pockets. I'm really looking forward to seeing how my first stainless steel extruder nozzle experiment turns out! The Wrong/Needs Improvement? Just the usual list of technical gripes: - I can't preview my store front and individual items as a visitor (anonymous or logged in) would see it. - Get licensing hooks (CC, GPL, etc) in place; I know you're working on it. - I haven't quite figured out how the star rating is supposed to work from the seller's side. For example, one of my Clover Connectors has been rated 3/5 but I haven't even received my own sample print to check against. Are they rating the design based on the rendering or because they got their fabricated version faster than mine?

Do you know of a recyclable 3D printing material?

The only recyclable 3D printing materials I know of are in the abstract sense. As long as the printing process is reversible, it should be easy to recycle. For example, wax can be re-melted, glass can be ground up and re-fused, some metal alloys (e.g. electrical solder) can be reclaimed and reused. Even ABS could be melted and extruded back into RepRap/Makerbot compatible filament. The developments made by the Open3DP project are particularly fascinating to follow.

3D printed & Hand Painted Gnome or Action Figure

nospam@example.com (Joris Peels) — Mon, 01 Feb 2010 12:50:00 +0000

Sean Dabbs has come up with some fun Shapeways Co-Creators. "You as a Gnome" turns you into a gnome. You upload photographs of yourself or a loved one and these will be sculpted into a gnome by Sean. The 25 cm gnome starts at $209. The picture below is of a hand painted gnome and this would be more expensive.

You can also choose to be turned into an action figure. Upload pictures of your face, select your body type, choose the clothes you want to wear and Sean will turn you into an action figure!!

KesselsKramer uses 3D printing & stop motion for Klokhuis

nospam@example.com (Joris Peels) — Sat, 30 Jan 2010 09:05:00 +0000

Dutch creative agency KesselsKramer has used 3D printing & stop motion to create an opening an closing sequence for Dutch children's TV show Het Klokhuis. The apples used for the stop motion sequence were 3D printed by Shapeways. The apples were made using our White, Strong & Flexible material and were so happy to have played a small part in this great video! The video is directed by John Kelly and you can read more about the people that made the video here. Check out the videos below.

Shapeways interviews Bre Pettis of Makerbot Industries

nospam@example.com (Joris Peels) — Wed, 27 Jan 2010 11:49:00 +0000

Shapeways interviews Bre Pettis (on the right), the Maker in Chief over at Makerbot Industries. Makerbot Industries makes an affordable desktop 3D printer and we and a lot of other people are very excited about them and their Cupcake CNC. We asked Bre about the future of Makerbot Industries and desktop 3D printing.

Joris Peels: What's a Makerbot?

Bre Pettis: A MakerBot is an affordable, open source 3D printer.

Joris Peels: And a Cupcake is a Makerbot?

Bre Pettis: Yes, the Cupcake is our flagship personal fabrication device! It makes things that are a little bigger than a cupcake!

Joris Peels: Who is the team behind Makerbot Industries?

Bre Pettis: Adam (Adam Mayer) has his head in the software, Zach has his hands on production, I'm making waves and we all start prototyping at 6pm when we stop answering emails, packing boxes and taking care of business.

What was the first thing you 3D printed?

A shot glass. Promptly filled with a deadly Scandinavian concoction.

Your favorite thing so far?

Everyday I wake up and check out what's new on Thingiverse and I'm never let down. Lately there has been a trend to make tools to do other things with a MakerBot like the MicroLathe. When folks are using the tools we design to make other tools to make other things it gets me excited. We make things that make things that people use to make things that make other things that make things. Try saying that 3 times fast.

Who came up with the idea for Makerbot Industries?

Zach (Smith aka Hoeken) had been obsessed with 3D printing for a while and infected us with the personal manufacturing bug. Making things that make things is fun so it's contagious.

How long did it take you guys to get the company going, to get the first bots out the door?

We started on Jan 17. Had the prototype done by Mar 17, and then had the first batch of MakerBots out the door on April 17th. There wasn't a lot of sleep in those months. We actually ate 2 cases of ramen in those months so we wouldn't have to go out and eat. That was a bad idea. Don't do that, it's not healthy.

What are the differences between a Cupcake and a RepRap (Open source 3D printer project)?

The main difference between a MakerBot Cupcake CNC and a Reprap is how much time it takes to make one. The Reprap project is an academic research project and it can take a few months to gather the materials and then put a reprap together and then a lot of experimentation to get it to print. The MakerBot CupCake CNC is a kit and can be printing things out after a weekend of assembly with a friend.

Are you really going to try to tackle 3D scanning too?

Yes. Having a MakerBot 3D printer and MakerBot scanner is the washer/dryer combo of replication. Who doesn't want to print out portrait sculptures of their family and friends?

And what new materials will you introduce?

We just launched PLA, PolyLactic Acid, and it's flying off the shelves. It's clear and it's made from corn. It smells a bit like butter when you print with it. We're finishing up prototypes of the frostruder which is a syringe based extruder that can print with frosting and anything squishable like UV curable silicon. And clay! We're in the market for a kiln so we can fire our own MakerBotted tea set.

What is a typical Makerbot customer like?

A lot of our customers are time traveling antique hunters which brings up all sorts of shipping problems. Most people think that all MakerBot customers are seriously geeky, but the truth is that even though lots of designers and architects and engineers buy them, most of our customers are just clever people who are sick of waiting on other people for their jetpack.

Will everyone have a desktop 3D printer? If so when?

When the Altair came out, people criticized it and said there wasn't a need for more than 10 computers in the world. We're in that same kind of place with personal manufacturing that personal computing was back then. MakerBots will be an absolutely totally common thing to see on a desktop within 10 years.

Why is Thingiverse important?

We built Thingiverse because we needed a place to share our designs so we wouldn't lose them and so our friends could make what we had made and then modify those designs and make them better. The community is amazing and supportive, and it's also a lot of fun. There is no other place that you can share a design for a physical thing and people around the world will make their own copies within minutes (NB: mmm we might need to do some more work in promoting our 3D parts database). It's that kind of sharing magic that makes Thingiverse the closest thing to teleportation that we've got in this solar system.

What are the mayor challenges for you guys?

It can be hard to find time to eat and sleep. There is way too much stuff to do in this world right now. If you're bored in this day and age, you're doing it wrong. Turn off the TV, pick a ambition and start spending your free time working on it. Besides 3d printing, there are all sorts of open source collaborative hardware projects to work on.

A while back you had an experiment in crowd sourced manufacturing with having people produce parts for Makerbots for you. How did that work out? Will you be doing this more often?

We were the first company to ever do crowd sourced manufacturing and it worked out great. It was so cool to have MakerBots in the wild making parts for unbuilt MakerBots. We've got some ideas to do this again that we're going to announce later this year.

How important is your community to you? What do they do for the company?

The MakerBot community is awesome. Because we're open source and the community is so smart, we've seen a lot of participation in the research and development sector. For example, MakerBot Operator Tim Myrtle ripped the guts out of our temperature control code and replaced that section of code with some serious PID math which made the temperature of the nozzle much more stable. Because we're open source, our users know that the code and designs are theirs to hack on. They also know that if they improve their machine, they can share their improvement and everyone in the community benefits.

Can I download a Makerbot and print it out using Shapeways?

Go for it! There was talk a while back on the MakerBot Operator google group to replace all the lasercut parts with printable parts. Progress is being made and already there is a printable extruder!

Are Makerbots going to be able to self replicate?

One step at a time. Self replication is cool, but our first step is actually to get the machine so that it can be an autonomous manufacturing factory. I want to be able to go to sleep and wake up to a pile of MakerBotted things next to my MakerBot!

Why did you guys start Makerbot Industries?

We felt compelled. We decided to live the dream. We followed our hearts.

Shouldn't you guys be making the next YouTube or something (Bre used to work for Rocketboom, Etsy & MakeZine as their video producer)? Why 3D printing?

We love the internet, but web apps are very 90's. Personal Manufacturing the new black. We see the future and it's full of flying cars, replicators, and moon colonies. You can watch videos of the MakerBot Operators popping our collars from the moon colony on youtube when we get there.

You used to be a teacher, is that still kind of your job? To 'teach' 3D printing?

My mission in life is to be able to develop infrastructure that lets humans be creative. I feel that very tangibly inside my self. When I taught school that's what I did. When I made tutorial videos that's what I did. Adam, Zach and I are taking creative infrastructure to a new level by putting the tools of manufacturing into the hands of creative people. Everyday, even the long days packing boxes, we get excited about empowering people around to world create amazing things with our machines.

Atoms are the new bits, The New Industrial Revolution & comparative advantage

nospam@example.com (Joris Peels) — Tue, 26 Jan 2010 19:24:00 +0000

Atoms are the new bits

is an important article in Wired by Chris Anderson about the democratization of production. It will frame the discussion about the business that Shapeways is in. To sum it up, "In the age of democratized industry, every garage is a potential micro-factory, every citizen a potential micro-entrepreneur." An even shorter summation, "the long tail of things" is coming.

It is thought provoking and inspirational article and everyone should read it. In my opinion however it leaves out several crucial elements that will allow "atoms to become the new bits."

1. Atoms will become bits only if the right infrastructure evolves.

Small entrepreneurs have to be able to defend their IP. Markets will have to be found. Customization and easy 3D modeling software will have to be created. Services such as legal, customer service, accounting, etc. will have to evolve. Customization tools will have to work. Recommendation engines for people, things and products that do not exist will have to be found, etc.

2. No amount of technology will replace the division of labor.

3. No amount of (available) innovation will eliminate comparative advantage.

4. Absolute advantage will not magically vanish overnight.

5. The invisible hand will still call the shots

6. Cooperation is not only a word on Sesame Street.

The most successful web publisher is not necessarily the best coder, builder of websites, writer of web frameworks, marketeer, authors, editor etc. Indeed even if he could do all of those things working with others would seem to be an efficient thing to do. The best designer in the world should probably spend more time designing than putting stuff in boxes. The best designer in the world might suck at marketing. The best designer in the world might be too expensive.

By working together and using the platforms available to us and using the skills of others in concert we will be able to achieve personal production. Networks of micro-businesses will define the future of commerce.

The key factor for someone who has or wants their own micro-factory or who wants to be a micro-entrepreneur is to specialize. In the New Industrial Revolution the core question will still be, what is it that you can do better than others?

Screws for 3D printing

nospam@example.com (Joris Peels) — Mon, 25 Jan 2010 13:08:00 +0000

Shapeways Community member Bill Morris has a fun blog called I Heart Robotics. Bill also has some great designs on Shapeways such as a Sonar Servo mount, chuck key Holder & a toolholder for Torx screwdrivers. In order to let people install the tool holders, Bill wanted to develop a way to use screws along with 3D printed parts. A perfect marriage between the old and the new, don't you think? You can check out his blog post here. Its good to see such development because I had personally given up on threaded screws used along with 3D printed parts. Bolts generally are much easier to use along with 3D printing and for the White, Strong & Flexible materials a simple hole will support a screw as long as the wall is thick enough. Thin walls along with screws might cause the material to tear thought. Bill however worked with the ABS plastic 3D printing material that we call Grey Robust. Its nice to see Bill showing us what is possible.

Joris Peels: Why did you want to use wooden screws together with 3D printed parts?

Bill Morris: I usually drill and tap holes because in many of the projects I work on
there is no way to access the back side to put a nut on. Nuts also have
a tendency to fall on the floor and loosen due to vibration.

After tapping hundreds of holes in 3D printed plastic I thought that
there had to be a better way. I wanted a solution that customers buying
stuff from my Shapeways store could reproduce without buying a set of taps.

I guessed that wood screws might work well, and looked for plastic
screws. While I am waiting for those to arrive, I decided to test the
wood screws.

Joris Peels: What machine and material did you use?

Bill Morris: Stratasys Prodigy Plus with P400 ABS.

Joris Peels: What was the most surprising thing about your findings?

Bill Morris: It was surprising that the wood screws had enough holding strength to
split the countersinks and split the screw bosses.

Joris Peels: Are you going to be doing more testing?

Bill Morris: I have ordered samples of these screws. Once they come in I'll do a similar test. I am hoping that they will work even better then wood screws since they don't have a countersink.

Stratasys and HP join forces to make 3D printers

nospam@example.com (Joris Peels) — Tue, 19 Jan 2010 15:41:00 +0000

Stratasys and HP are going to make and distribute 3D printers together. This is huge news. As you may know Stratasys is the company behind the Dimension & Fortus 3D printer brands and the Red Eye 3D printing service. Stratasys use the FDM process and we use their machines for our Grey Robust material. Some quotes from the press release: “We believe the time is right for 3D printing to become mainstream,” said Stratasys Chairman and CEO Scott Crump. “We also believe that HP’s unmatched sales and distribution capabilities and Stratasys FDM technology is the right combination to achieve broader 3D printer usage worldwide. HP has made a similar move in this market before, capturing a dominant position in large-format 2D printers. Together we hope to repeat this success with 3D printers.”

The large printer manufacturers have now dabbled in the "low end" of the market with Dimension FDM printers breaking the $20,000 mark at one point. This is the same price as the entry level Zcorp machine, the 310. Objet's Alaris is around 40,000 if I'm not mistaken. Now the Dimension U-Print starts at $12,000. 3D Systems, another 3D printer manufacturer, recently acquired the assets for Desktop Factory which was a start up that wanted to produce a $5000 3D printer.

Stratasys working with HP means that they will have a lot more muscle on the distribution side and will push prices lower. HP's savvy in doing the whole "giving you the printer" and charging an arm and a leg for the ink thing. It would be interesting if they tried this with 3D printers. This is a huge shake up in a market coming to grips with the idea of manufacturing for everyone.

The race to lower prices and desktop machines is of course even more interesting given that the open source Rep Rap printer (and its positively dirt cheap $750 Makerbot Cupcake CNC variant) are both doing very well. This means that as of now the major 3D printer manufacturers are locked in a battle for your desktop while at the same time trying to figure out how to compete with open source. Awesome!

Shapeways Community Tool Script for Blender & texture map tutorial

nospam@example.com (Joris Peels) — Mon, 11 Jan 2010 15:05:00 +0000

Eric Finley and Aaron Trocola rock! I am continually astounded by the helpfulness and kindness of the Shapeways community.

As you know we recently introduced color 3D printing. To upload and create a color 3D printed file you have to work with a texture map and the VRML file format. These are both unfamiliar to a lot of people. Aaron therefore spend a considerable amount of time making a clear and well illustrated tutorial explaining the texture mapping of VRML files. His tutorial shows you how you can use the free Google Sketchup tool combined with the free and open source tool Meshlab to easily make textures out of images. His example of a simple photo frame is clear and the tutorial is a huge help to our community. I would like to thank Aaron so so much. You can check out the tutorial which will help 3D modelers from noobs to ninjas deal with texture maps here. Besides writing super tutorials Aaron is Aeron203 on Shapeways and has some really well designed items in his Shop.

Just having one person such as Aaron do something so helpful would be amazing but over the past weekend we had two. Eric Finley made his Shapeways Tools Script for Blender. This script integrates and builds upon the work of another awesome member Loonsbury. Loonsbury's pricing script for Blender is now included in Eric's Tools. This means that community members have now made tools for Blender as well as for 3D Max in the form of Virtox's excellent pricing script.

Eric's Shapeways Tools for Blender include a completely automatic wall thickness check. You are not dreaming. The script even color codes your wall thicknesses so you can see where your problems lie and just how problematic the walls are, right within Blender! Please help Eric by giving him feedback for his awesome app. You can check out his great fantasy Shop here.

The Marlyand Plastics Injection Molding contest

nospam@example.com (Joris Peels) — Thu, 07 Jan 2010 19:41:00 +0000

Together with Maryland Plastics we will have a contest to see if the creativity of our community can lead to excellent design in injection molded tableware. The winner of the contest will receive $300 in 3D printing from Shapeways.

The top 3 entries will then be evaluated by Maryland Plastics and if the designs meet their exacting standards they will offer the designer a buy out fee. This could mean an additional fee of $2000 for example. But this would depend on the design being injection moldable.. The design has to be injection mold able and fit into Maryland Plastics Crystalware line. You can enter the contest by uploading a model with the tag: injection molding to Shapeways. Your design will remain your own property unless you decide to accept an offer from Maryland Plastics for the rights to the design.

So tired of all this boring unique, one of a kind stuff? Injection molding, is about millions of copies.

Rules to be Injection Mold able:

The easiest thing to do is pick up something that is made in plastic. You can even look through the Maryland Plastics Catalogs and see how it works. In most cases, a Mold is 2 pieces of steel, that are held together at high pressures, and liquid plastic is injected in the cavities. Then the 2 pieces of steel are pulled apart and the plastic pieces fall out. This can be seen on any injection molded piece. If you look at a plastic fork, there is a seam that runs along the entire perimeter of the fork. This is where the pieces of steel meet. On a plastic bowl or plate, it is usually along the brim. This seam is very important in your design. You must leave a way for the steel to escape.

For example, this punch bowl shape. Think of 2 pieces of steel. How would you have two pieces of steel to make this design, and then be able to remove the plastic piece? It would require extra moving pieces and be extremely expensive. And when you go to buy plastic stuff, you don’t want expensive. In some cases a 3 piece mold is required.

In the case of a coffee cup or pitcher, a 3 piece mold is acceptable. It is had to design a handle in a product that wouldn’t require a third piece. If you think about how the steel would need to escape from the plastic, you would see that one piece of the mold would be for the inside of the cup. Then you would need 2 pieces to move in from the sides of the cup to make the handle. If you just had a 2 piece mold, the steel would not be able to pull out from the handle.

Rules for Crystalware:

When you look through the Crystalware catalog, you will see many items ranging from platters to pitchers to plates. What we are looking for is one of two things. Something that will fit along with the items we already have. Or a design of it’s own that would look good in clear plastic. For example you like the design on the pitcher. You could make say cups that compliment the design. Or if you hate the design on the pitcher, and you think another design would look better.

Good luck guys!

Several community members have been making some wonderful things over the past months to showcase Full Color 3D printing.

Upload an image and it will be made into these wonderful marbles that cost $10.

We turn any image into a color 3D printed depth map so you can see as well as touch your holiday snapshots for $29. Check them out here.

For Character modelers & animators this really means they can now take their avatar or their favorite character design and put it on their desktop. Designers can now come up with Co-creators that can be turned into any color, any pattern such as this Ipod accessory below. You just upload any image or pattern and the designer easily makes your object this color or pattern.

Expectation Management

The type of 3D printer we use for this process are Zcorp 650. We however are using a finishing technique that strengthens the 3D printed parts using rapid thermoset composites. Additionally we also use a one of a kind machine to resin infuse the models. This unique process makes the models much stronger and the colors much brighter, than was possible previously. We believe that people that have been exposed to Zcorp previously will be blown away with the results.

Having said that we do have to temper your enthusiasm somewhat. The resolution of the printer itself is low compared to the other processes we use. So the details and features will be less accurate. However, the color resolution is high so high detail in images is possible. The models are much stronger than traditional Zcorp processes but still fragile compared to the other things you can make with Shapeways.

We have more technical information here in the Design Rules for Full Color 3D printing here. The most crucial information is to realize that the wall thickness is 3mm and that fragile dainty models can not be made with this process. For a quick overview of the material you can check out our material page for Full Color Sandstone.

You can currently add color to your models by using a VRML file with texture map or by using x3D. You can find out how that works here.

Please tell us what you think and especially in the first weeks of this new material, let us know what needs to be improved.

1,000 True Fans

Kevin Kelly has done it again. In his post about 1,000 true fans he details how a designer, artist or any independent creative can make a living as long as they have 1,000 true fans. If you would like to make a living in a long tail world where anyone can make anything and anyone can design anything then please read this post. If you want to use tools such as 3D printing to make a living, then please read this post. If you are a designer, artist or creative on Shapeways, and would like to make a living on our platform, then please read this post. Or if you just want to start a business at one point, then please read this post. I don't know how he does it but Kevin Kelly has through the morass identified and described quite possibly the most important element of becoming successful while using todays democratizing technologies. It is also a quite clear path forward for anyone wanting to turn a hobby and/or a dream into a living.

"I am suggesting there is a home for creatives in between poverty and stardom. Somewhere lower than stratospheric bestsellerdom, but higher than the obscurity of the long tail. I don't know the actual true number, but I think a dedicated artist could cultivate 1,000 True Fans, and by their direct support using new technology, make an honest living."

I can not stress this enough, please read this post.
