Especially for Baroba, a picture of his Bowie the bunny model in Stainless Steel. 

We 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.   

We'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.

The Shapeways Co-Creator Platform and what it means

Co-Creation is the general tendency of companies to work together with their customers in order to create value for them both. CK Pralahad, one of the co-coiners of the term has said,

”Think of Google. I can personalise my own page, I can create iGoogle. I decide what I want. Google understands that it can have a hundred million consumers, but each one can do what they want with its platform.”

With iGoogle, Google makes the platform, the content is provided by Google and many other publishers and users make it meaningful by personalizing the page to their liking.

The Shapeways Co-Creator Platform is our way of taking co-creation and 3D printing to combining the two. 

A designer can take a single design and turn that design into a template. Within the variables set out by the designer the buyer cant hen adjust or specify his own unique design within the confines of that template. Shapeways does the production, shipping, billing & customer service.

The customer can then very easily customize, personalize and create his own unique objects to his or her specifications. The Co-Creator Platform allows anyone buying a gift, for themselves or others, to tap into the skill and creativity of the thousands of designers, artists & animators on Shapeways.

A designer can now take any design they have and using Shapeways make it into something others can adapt and customize. The advantages for the designer are:

• Ship & sell real physical objects worldwide with start up costs of a few hours of your time.
• Make unique designs for others in comparatively little time.
• Initialize and own the initial creativity and creative process.
• There is also no risk of designing something without getting paid

This last point is the biggest practical difference and most unique thing about the Co-Creation platform. You could have previously entered into design competitions or do work made to order online. But, these both bring risks to the designer.

In a “made to order” scenario all the work before the customer agrees to buy the product is a risk taken on by the designer. Small errors in scoping, finding out what the customer wants could waste hours and end up underpaying or resulting in the designer not getting paid at all. Even if all goes well the constant pitching, emailing back and forth, negotiation and work to get a customer to choose you is a waste of the designers time.

Competitions are really made to order work whereby hundreds of thousands are asked to do a “made to order” assignment but where you end up paying only one. This clearly would provide uneven & unsure returns for participants. A competition is great for the organizer because it means that much more effort goes into your design than if you just paid one person. This is why we use competitions for fun and to inspire our community on Shapeways. However, when it comes to tools that we deploy to let our designers make money we have purposefully avoided competitions.

With a template a designer knows ahead of time how much time he or she will spend in customizing each resulting design. The returns for the designer would be more constant and more predictable. The designer gets to decide how much they want to earn for a quantity of work that they can estimate. And possibly most importantly the customer only comes to them once they've already paid for the product. This means that expectations, returns and deliverables are managed for both the designer and that designer's customer on Shapeways

We think that the Co-Creator Platform points towards a future where consumers can design many of the objects that populate their lives and where designers can become “brands of one” by having their own production capacity.

Please note that co-creation does not consist of co-developing or co-designing products themselves. This process is co-design and could also occur between designer and customer but a better example of this would be our Creators such as the Ringpoem Creator.

For an overview of some short definitions of the relevant buzzwords you can check out the list below.

Mass customization- Is allowing the customer to have and even create is own individual product or experience.

Co-design, also spelled codesign is when a customer gets together with a designer and they both design the final product together.

Open innovation: is the collection and collation of customer input and ideas to develop new services, products and concepts.

Crowdsourcing is when a group of people are asked to perform a certain task or tasks to help achieve a common objective.

Co-Creation is the general tendency of companies to work together with their customers in order to create value for them both. A classic example of this is iGoogle or Netvibes where the company provides a platform or tool that the customer can personalize to his or her liking.

Competitions as in a traditional design competition is in my opinion none of these. Since it is just a 'brief' you send out to many people and end up paying only one. This is not the route to go through because in the long run it would limit the quality, variety and earning potential of our community.

“made to order” according to me does also not apply since it is simply a brief that one would send to a single person asking them to build whatever the brief says. Granted the difference between the Platform and made to order is at first glance a small one but by putting the designer in charge of the initiation of the project will over time lead to significant deviation between the two.

Depending on who you listen to or how narrowly or broadly define each term, what Shapeways is doing could possibly be all of these terms.

Our Creator products are pure mass customization tools. We develop a piece of software and a template and the customer gets to, within the confines of this template, create his own unique product.

Shapeways as an upload service whereby people get to upload their own designs that we can then produce could also be seen as mass customization & co-creation.

Our Shapeways Shops where any designer can upload a design and then sell it could be seen as co-design, open innovation, crowdsourcing and even co-creation itself.

The community member feedback, forum discussions and emails we listen to and discuss actually make up a significant portion of our own software development roadmap. With a little stretch this could be seen as co-design, co-creation and even crowdsourcing.

Now that you know the future of production and design, what are you going to do about it?

You 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 far as post processing the 3D prints are concerned you can weld it, machine it and drill it. If you do want to drill it, we'd advise you to use carbide drill bits.

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!

We have a great contest for you this month. We're doing this contest together with AutoDesSys the makers of Bonzai3D. The contest will run from August 4th until September 4th. The theme for the contest is "make your dream home or anything in it." So this is a contest for architects and aspiring product designers. What kind of dream items would be in your dream home? What would your dream home look like? 

We really upped the ante in prizes also this time. Together with AutoDesSys we're giving away:

$300 in 3D printing and Form.Z RenderZone Plus(Prize valued at $1800) for the first placed winner.

$200 in 3D printing and Bonzai3D($700) for the second placed winner.

$100 in 3D printing and a Bonzai T-shirt(priceless!) for the third placed winner.  

You can enter by using Bonzai 3D to make your model. You can download the free trial version of it here. The tag you add to your model is: b3d. The competing models will be added to this gallery page. AutoDesSys management will together with Shapeways decide which model is the best "dream home" or dream item for in a dream home.  

Have fun guys!  

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. 

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.
