Thursday, August 27. 2009I will be on vacation until the 7th
Hi everyone, I will be on vacation until the 7th of September. I wanted to give you guys a heads up because I personally hate getting out of office replies when I'm expecting a response from someone. If you have any questions you can simply mail service (at) shapeways (dot) com and Nikki and Ralph will get right back to you with the answers. Bart & Peter will do some blogging while I'm gone and meanwhile I will be rearing to jump back into the thick of things for you guys.
Wednesday, August 26. 2009De Fietsfabriek personalized bicycles
De Fietsfabriek is an Amsterdam based bicycle manufacturer founded by Yalcin Chichangir & Dave Deutsch. The company has its own factory in Turkey and the bicycles are assembled in Amsterdam. The Fietsfabriek first became popular with hip and useful versions of the Dutch Bakfiets. A bakfiets is basically a heavy duty bike with a large container attached to the front of it. Bak=container, fiets=bike. In the olden days people used to use them to transport and deliver almost anything in the Netherlands but the bakfiets had long since been replaced by cars, that is until the Fietsfabriek brought them back.
Above you can see a camo color bakfiets. I spoke with co-founder Dave Deutsch about the Fietsfabriek & personalizing bicycles. The company does not see other bicycle manufacturers as their competition, their bikes are meant to compete with cars. Indeed Dave has many examples of people getting rid of a second car after buying a bakfiets. People use the bicycles to do shopping & go to the zoo with their kids in the bak. The bikes are sturdy and you can fit a lot into them. Their customers are mainly to be found under the ecologically conscious and trendy people in major cities. They currently have ten stores in the Netherlands as well as franchise stores in Chicago & Berlin. The Fietsfabriek got into bicycle customization & personalization because they wanted to help protect their customers from theft. A bakfiets can cost 1500 Euro's. The Fietsfabriek had an innovative idea: we make all our own bikes anyway so how about we let people put their names on them? That way there is less of a chance that someone will steal the bikes.
Later on people requested more colors and companies started to make bikes in their colors and with their logos on them. You can also have a hand painted bike or your very own unique configuration. Customization can start for 95 Euro's. For that money you can get a laser cut & powder coated plate mounted on the bike with your name in it. Some people are building bikes to their very own precise specifications & size. Soon you could actually visit the Fietsfabriek's factory in Turkey and be there for the initial fabrication of your bike. I think that the Fietsfabriek is a great company. It is rare to see a business start out nowadays that does all of its own production. Their products are very high quality and I love the fact that customization to them is a means to an end. Their bikes are above all else practical and filled with good useful design.
Above is a hand painted small bakfiets.
This type of bike is very trendy in the Netherlands at the moment. The plastic crate on the front is an easy place to store your stuff. On the back there is a comfortable cushion for people hitching a ride on your bike. These kinds of utilitarian considerations happen if you actually use a bike as a mode of transport.
Lets say you have twins?
This bakfiets has been specially made to transport people in a wheelchair.

Wednesday, August 19. 20093D print of Bowie the bunny in Stainless SteelEspecially for Baroba, a picture of his Bowie the bunny model in Stainless Steel. Introducing: Nikki, the newest Shapeways team memberSome of you have maybe already met me via the service (at) shapeways mail but I haven’t had the chance yet to formally introduce myself. I’m Nikki, and I've been here to help the rest of the Shapeways team since the beginning of June this year. My job is to make all of your lives a little bit easier. I chase down your orders, answer questions about them and help you make your models printable. I also help with the administration & planning of orders and shipments. I’m still a student, studying Advertising, Marketing & Communications in Amsterdam. In September I will start my 4th year, hopefully I will graduate next summer. I love to design in 2D using Illustrator, Photoshop and InDesign. I am learning to make illustrations and I make a lot of posters, flyers and logos. When I grow up, I want to work on the creative side of marketing. At Shapeways I hope to learn some 3D modeling and get more involved with the Shapeways site & brand. I recently moved to Eindhoven. I love dance music and go to a lot of parties such as Lowlands. I also love the Internet(love to read blog posts, not write them). I'm very happy to be here at Shapeways and look forward to seeing all your emails, questions and designs! Tuesday, August 18. 2009Metal 3D Printed: minotaur, wire ring and wrapped ringWe got some more photos of some of the models we displayed at SIGRGAPH, the metal 3D Printed: minotaur, wire ring, wrapped ring and Bowie the bunny. Thousands enjoyed touching these models and we think they really illustrate what is possible now.
The Wrapped ring model is not a finger ring per se as it is much larger, more of a too small bracelet.
The Wire ring is a finger ring, it costs less than $11 including shipping so shows you how affordable you can make things in Stainless Steel. You can see the definition of the printing process clearly in this close up photo.
The minataur is a piece for a boardgame. It is 3.9 CMs high and costs $39 including shipping. Friday, August 14. 2009Shapeways is looking for an experienced graphic designerWe're looking for an experienced Designer for Shapeways in Eindhoven. I know many of you from all over will be interested but we can not offer relocation or "work from home" for this position. So this job opening is for people in the Eindhoven area only (sorry). If you are an experienced designer in the Eindhoven area that has mad Photoshop, Illustrator & inDesign skills complemented with Flash and some 3D modeling experience, we're looking for you. Come check out the job listing on the jobs page. We need someone that can both do the design work and work with our team to develop new Creators and the overall look and feel of Shapeways. Do you want to help determine what the future of co-creation and 3D printing look like? Join us.Wednesday, August 12. 2009The Shapeways Co-Creator Platform
The Shapeways Co-Creator Platform and what it means
Now that you know the future of production and design, what are you going to do about it? Tuesday, August 11. 2009Stainless Steel for allYou guys might have seen all the press we have been getting about the Stainless Steel printing. We had a Crunchgear article, a FastCompany one, a Wired one and lots more besides. That coupled with the many many many people we met at SIGGRAPH means that it is quite busy right now on the site with people who are new to Shapeways. It would be great if you guys were kind to all the noobs and helped them out should they have any questions. I mean noobs in a nice way. The Stainless Steel material has been added to all models on the site, so you can now check the prices of your models in Steel. The price per cubic centimeter is $10(including shipping of course). We can not currently guarantee that all the models that you order will print. Since the process is new we have not been able to develop completely 'watertight' software filters to check this. We do know that for the model to succeed a wall thickness of 3mm is required. To clear up: the models that we ship to you, that you can now make are stainless steel and bronze through and through. There is no cast, it is not a covering or layer over a plastic model, the entire thing is steel and bronze and it is built like that. We've been getting a lot of questions from engineers about the material properties of our 3D printed Stainless Steel. So here are the answers: The UTS (Ultimate Tensile Strength) is 99 KSI / 682 MPa. If you compare this with other materials the tensile strength of our Stainless Steel material is: higher than aluminum, higher than structural steel(as in the steel used in buildings in the US), much higher than cast iron but lower than titanium and regular stainless steel. The yield: 66 KSI (455 MPa) The modulus(Poisson Factor/material constant): 21.4 MPSI (147 GPa) Elongation: 2.30% Hardness: 25 HRc
As you can see, apart from being awesome and fun to use for rings, jewels and lovely interior decoration items these values give our Stainless Steel material quite some other uses. People have already tested this for turbine parts so something like that would be completely boring. But, perhaps the strength could inspire you to make something interesting? We just put a factory in your mouse, enjoy. Why are you still reading this, go upload something and have it made in Stainless Steel!

Sunday, August 2. 20093D printing with DNA, Community Member interviews, Bjorn Hogberg![]() Bjorn Hogberg, Phd is a research fellow at the Shih Lab, Dana-Farber Cancer Institute Department of Cancer Biology at Harvard Medical School. He is also a Shapeways Community member. I was intrigued when I saw his post on our "it arrived" forum mentioning his DNA slotted cross. The "DNA origami" model that he had printed with us looked nice enough and referenced an article in Nature.
I checked out his website and asked Bjorn what it all meant, and he completely blew my mind. Seriously and without hyperbole. Bjorn and his fellow researchers are currently working on 3D printing with DNA. They are attempting to let DNA self-assemble using a technique called DNA origami. They hope to use this technique to make drug delivery systems & molecular machines. Joris: What exactly is "building with DNA?" Bjorn: Well, DNA in our cells is used mostly as an information storage device. Almost 30 years ago Ned Seeman at NYU came up with the idea to use DNA as a building material. Today, DNA nanotechnology is all about just that. Ignoring the biological function of DNA and just treating it as molecular putty. How can something self-assemble? This is where DNA excels compared to many other molecules. Im sure you have heard about the A,C,G and T bases that every DNA chain is built up of. In a DNA double helix A pairs with T and G pairs with C so if you mix for example a AAAA molecule with a TTTT molecule they will find each-other in the solution and self assemble to form a double helix. A few years ago, Paul Rothemund at
Caltech, discovered that if you mix a long DNA molecule with some
200 cleverly designed short DNA molecules, these short DNA molecules
can attach to the long molecule in such a way that they fold the long
molecule to whatever shape you want. Among a bunch of other designs, he
self-assembled a nano smiley that has become quite famous. The
technology developed in our lab is an extension of this technique that
allows us to self-assemble complex three dimensional shapes. What shapes are you able to make? The shapes we can make are limited in size by the DNA molecules we use. Today most object we make are around 40-50 nm long in all dimensions. The "voxels" we use are basically small chunks of DNA double helices about 6x2x2 nm big so the structures are also quite "pixelated". This paper contains a small gallery of the shapes we are able to make, some structures with curvature has also been made by Hendrik Dietz, another post doc in our lab. They have not been published yet but his webpage contains a preview of those curved things. What are these structures useful for now? Now, there is basically only one 'useful' application and that is to make small stiff rods of DNA that provides a way to determine the structure of membrane proteins by nuclear magnetic resonance. The structure of this particular class of proteins is notoriously difficult to solve so the technology fills an important gap. What could they be used for in the future? 3D printing at the nanoscale for hobbyists (although you would need a pretty expensive electron microscope to actually see what you built). Rational design of molecular machines that could be used for example as smart drug delivery vehicles. Circuit construction for nanoelectronics. Is this really 3D printing with DNA? Yes I think it is. You could argue that anything that self-assembles isn't really printing because there is no machine that is doing the actual printing, its sort of a 3D powder printer in which the powder just sticks itself together in the way you want when you shake it in a test tube. In the Nature piece you say:"We anticipate that our strategy for self-assembling custom three-dimensional shapes will provide a general route to the manufacture of sophisticated devices bearing features on the nanometre scale." What do you mean by devices? In that case we are talking about molecular machines. Our body is filled with wonderful little molecular nanomachines called proteins. They are very good at what they do but we basically have no idea how to re-design them to do something else. DNA nanotechnology provides us with the means to rationally design new molecular machines. What is a molecular machine and how could it be used? For example the ribosome, it reads the sequence of a gene, and produces a protein according to the sequence it gets. This little machine that exist in many copies in every cell on the planet is an excellent example of a molecular machine. It took some billion years to evolve by evolution. In the future, we might be able to build our own molecular machines. Will these things have applications in biotech, medicine, beyond? First I think we will see applications in biotech and medicine. Molecular machines that we might produce with DNA include a drug delivery vehicle, it could for example be programmed to release chemotherapeutic drugs only when it enters cells of a growing tumor. On a longer time frame, I personally believe that building schemes such as this will be used to build circuits for nanoscale molecular electronics and quantum computers. ![]() Talk to us about your DNA Origami Slotted Cross model: This model I designed to use at presentations when I describe my cross design. Its basically a 3D schematic that in a stylized way shows how the long DNA chain winds its way through the entire design. I also thought it would be cool to have a macroscale version of the cross design, a 2 million times enlarged version. ![]() Why did you print it with us? I've been interested in 3D printing for more than 2 years. I wanted to build myself a CandyFab (http://www.candyfab.org/), but the move to a smaller apartment in Boston with a new job as a post-doc slowed those plans down. When I fund your site I though "This is exactly what I have been looking for". The fact that you upload your file and immediately get a yes or now for printable along with a price, thats almost like having your own 3D printer. What is caDNAno? When I first came to this lab we all designed our structures by drawing a large schematic in Adobe Illustrator, then manually transferring all the coordinates to a custom python script that would calculate the DNA sequences we needed to order. My cross design probably took like 3 weeks to design if you include the rigorous error checking we all had to do on our designs. It was a pretty error prone and time-consuming process to design a new shape. Shawn Douglas in our lab wanted a better way to design stuff so he wrote caDNAno, now using his software the design process is much less painful and the probability of making small errors is decreased. Its a great step forward in spreading the use of this technology. In the Nature article you guys say that "we seek to demonstrate actuation potential and mechanical controllability of prestressed DNA tensegrities, to create DNA-protein chimeras that integrate defined 3D DNA nanostructures into natural extracellular matrices, and to use these artificial matrices to control mammalian cell behavior and multicellular organization by mechanically actuating physical changes in the internal DNA nanostructures." This to me reads very sci fi. Does it mean that you will 'print' a structure that will make changes in the body? Yes, that project has an ambitious goal and it is not clear that this is exactly how it will work, but in principle it should be possible to make a DNA nanostructure that react to a chemical signal in the cells and in turn make its own changes to the cell. In fact this is already how cells work, what we could contribute is a way to make it easier to 're-program' certain cell functions. This probably lies many years ahead though so I guess you are right when you call it sci fi.
