Design your prototype in a 3D software package, save your CAD drawing in “.STL” format. Upload it for a customer service representative to take a look and gather a quote for you, then wait for your package to be delivered!

 

 

How to save a .STL file from the following popular 3D CAD programs.

The old adage…garbage in equals garbage out is still true in the 3D printing world. A successful prototyping project begins with the creation of a good .stl file. If the export settings in the CAD program are not set properly, your exported .stl file could have facets which may result in an inferior product. Below are some of the more popular CAD programs and instructions on how to export a quality .stl file from each program.
