Design rules & detail resolution for 3D printing

I’m very excited to announce that we have put yet another designing mechanical parts tutorial live. The third tutorial follows the first one that deals with material properties and the second that shows you the design issues of an actual project. This third installment is extra special. This is some of the most in depth information ever published online with regards to Selective Laser Sintering(SLS). Furthermore it is not some marketing blurb that you can find all around. This is actual testing information that if you understand & use it will let you know more about 3D printing than most everyone.

SLS is the process behind our White, Strong & Flexible material. This tutorial is nothing less than initial design rules & in depth information on the detail resolution of the SLS process. This information is based on research conducted by Dominik Sippel for EOS GmbH. EOS one of the world’s largest rapid manufacturing machine manufacturers. They have decided to share the accuracy and technical information behind their technology, with you.

Detailed graphs and tables show you gap sizes, gap deviation, wall thickness, hole accuracy, etc. This is huge. An engineering driven company in the very competitive rapid manufacturing business wants to give you, the Shapeways community, accurate hereto internal data so you can use this information to design and make things.

With online and open source we have been coddled with documentation, API’s and outreach by the people who make a product to the people who use that product. We think nothing of downloading some source code here, messing about in someone else’s Bugzilla or reading release notes. Good luck though in trying to get detailed information on the limitations of your toaster or the schematics of your LCD TV.

In manufacturing it is virtually unheard of to let people in on your own research and to reach out to them as EOS is doing here. A lot of people are talking about opening up R&D, co-creation, reaching out to inventors and consumers alike. But, very few are actually doing it. So, once again, this is huge. It might seem a bit boring and a bit nerdy, but it is huge. On to the design rules tutorial.
