3D Printing Resources
Software:
Many more a Google search away, but how to choose one? Answer the following:
Can it save in STL or OBJ (most common formats for printers)?
Are there free or discounted versions for students and teachers?
Do education versions have some capabilities removed that you need?
Is there an active user community (free support) online?
Does my printer manufacturer provide one?
The software to prepare prints is NOT the same as a modeling program.
Try to use it before you set the students free on it. You may find that some are too buggy or have hidden costs not shown on the download page
Ex: 3DTin.com has been found to be very likely to crash
Hardware:
2015 3D Printing issue of MAKE https://makezine.com/volume/make-42/
Before choosing hardware, we would always recommend searching for the latest reviews. Every year, MAKE magazine does a roundup review of 3D printers that is very helpful. The field is young, so last year’s brand may not be the best deal anymore.
