Makerbot’s Lawyer Explains Thingiverse Terms Of Use

Apparently Makerbot’s in-house lawyer has more important things to do than explain legal jargon to the public.

In a concise and coherent post, Rich McCarthy explains how Makerbot has structured their legal relationship with Thingiverse contributors. The short of it is that they are using roughly the same terms as sites like Youtube.com, they make no claim of ownership on anything uploaded to Thingiverse, and whatever license you attach to your work (like Creative Commons) they respect.

Well…that’s it. I don’t like doing tiny posts, so here is Josef Prusa explaining how to use the “new” Makerware program with old “unsupported” Makerbot printers.

The Definitive Makerbot Open vs Closed Source Discussion

I did my best to document all the different points of view that are relevant to the open source hardware world but are spread all over the interwebs.

The original Makerbot founders.

This post got big, fast. Really big. After the jump you can find key quotes from Bre Pettis, Zachary Smith (Hoeken), Adrian Bowyer, Josef Prusa, etc.

Science Enabled By Open Source Hardware

Science is a good match for the open source philosophy.

Because…

  • it tries to do things for little-to-no money
  • it doesn’t care if equipment is pretty
  • it is only focused on results
  • it needs things that are very specific that no one else in the world needs
  • it is often motivated by something other than profit

Joshua Pearce of Michigan Tech’s Open Sustainability Technology Lab is an example of where the rubber meets the road. He has nearly two dozen Thingiverse things, and most of them are awesome tools for scientists. His work has been profiled in Mighigan Tech News and Popular Mechanics. You can also read the transcript of an interview with Science Magazine Podcast here (pdf). Pearce has a paper called Building Research Equipment with Free, Open-Source Hardware in Science Magazine, but it’s behind a paywall. The summary is here.

3D Printable Lathe

Thingiverse user Sublime has made this nifty mini-lathe that is mostly plastic parts printable on your average friendly neighborhood 3D printer.

Gary Hodgson DLP Resin Printer Lessons Learned

In the never ending quest for higher 3D printing resolution, the hobby community has naturally turned to DLP (digital light processing) in which a liquid polymer is selectively hardened by a projected image. ScribbleJ’s Thingiverse entry is a good first step. Gary Hodgson has written up an excellent analysis of his DLP printer here.

All The Plans for PENSA!’s DIWire Aluminum Wire Printer

A little while ago PENSA! wowed (a specific section of) the open source maker community with a few teasers for a brand new desktop rapid prototyping machine.

Their DIWire (DIY’er…get it?) takes aluminum wire and bends it into any shape specified in a wide variety of file formats. It’s a compelling idea and now that they’ve released all of the design files on Google Code and Thingiverse the community can start using and improving it.

Printable Folding Construction Demonstrated With Robots

Sometimes you just can’t get from where you are, to where you want to be, in one step. For example, open hardware tends to work with stock materials, which means flat sheet is popular. It’s usually cheaper to obtain and work than a large block of the same material. But there aren’t very many ways to use a flat sheet if it stays a flat sheet. A couple popular ways to fold a flat sheet into a useful volume are illustrated.

Parametric Flex Box by Juerd. Thingiverse #17327

Can this folding idea be taken even farther? For example, can we fold flat surfaces not just into structures, but into mechanisms as well?

3D Scan Cleanup by Tony Buser

3D scanners are great, but they create “dirty” meshes. Overlapping points and reversed normals don’t matter until you try to print the mesh on a 3D printer. Then the slicing engine will get confused because it can’t tell where the inside/outside of the model is. Correcting these “dirty” meshes involves a lot of tools, some expertise, and a little bit of luck.

Tony Buser has provided an excellent tutorial describing his process. He takes a 3D scan, massages it through several different programs, and the result is a perfectly printable 3D model.
