CAD (Computer Aided Design) Programs

CAD programs are used to design custom 3D objects and there are several programs on the market.  You can use any CAD program to create your design as long as the program is able to export the 3D file into one of these formats:

  • Wavefront OBJ (*.obj)
  • ASCII STL (*.stl)
  • Binary STL (*.stl)
  • Thing (*.thing)

Preparing Model for Printing

Below are step-by-step instructions on how to prepare your 3D model to be printed from either TinkerCAD or OnShape.  

Saving and Sharing Models

TinkerCAD automatically saves models every few seconds when using the program in your browser, but if you would like to share your model with a friend so they can print or edit, here are some options:
  • Make your model public and anyone can search for your part name in the TinkerCAD library.
  • Upload to Thingiverse 
  • Export your file as a STL file. This file can be imported into MakerBot Desktop or TinkerCAD.
OnShape also automatically saves models every few seconds. If you would like to share your model, OnShape has a few options:
  • Click on the SHARE button and you can enter email addresses to share this document to edit or view (similar to Google docs).
  • Export as an STL file.  This file type can be imported into MakerBot Desktop or TinkerCAD.
  • Export as a SOLIDWORKS file.  This file type can be imported into OnShape.
