3D Printing has been riding the classroom innovation wave for a couple of years now — have you tried one in your classroom?

Here are a few of the apps and articles that we have found useful when getting started (or going further) with 3D printing!

If you are a middle school teacher in Hawaii, sign up to borrow an assortment of 3D printers from the Toolkit for Teachers!

3D Design and Modeling


Autodesk Apps

  • Autodesk has some really great apps, most of which are free.  Autodesk Sketchbook, 123D Catch, 123D Sculpt are quite good.
  • App Store Link


  • Primarily CAD Software, but a good modeling experience on the iPad.  Has a free version, but the more interesting features are pay.
  • App Store Link



  • A free, web-based app that is an excellent introduction to the basics of 3D modeling.

3D Model Repositories


  • Definitely the biggest and best source of free 3D models to print. They even have an excellent section on educational models. Be sure to get lost in here for a while.
  • Thingiverse Website


  • Another good one—-not as big as Thingiverse, but definitely worth it.

HP 3D Printing Glossary

  • Everything has its own special word, and HP has your back for figuring out what they all mean. (And a BIG thanks to the Lyndhurst Girls’ STEM Club for sharing this!! Aloha, everyone!!)
  • 3D Printing Glossary


  • The one and only NASA has an ever growing collection of 3D models available for their primary missions. Some of their models tend to be a bit too complex to print straight out, but there are often printable versions available.
