Preparing 3D Models
Before an object can be printed, a 3D model must
be converted into G-code by slicer software. Most
3D models are saved as .STL files, and there
are many resources available to download .STL
files for use with 3D printers. In addition, there is
a wide range of free CAD software available for
those interested in creating their own models.

Creating 3D Models
Many free resources exist that provide 3D models
for download. Of note,
www.thingyverse.com is
a repository of over a million 3D models available
for free download. Most of these are shared via
a creative commons license, allowing users to
adapt and redistribute models for non-commercial
purposes as long as proper credit is given.
TinkerCAD, FreeCAD, SketchUP Free, and
Blender are free-to-use design software. These
programs have different strengths and weakness-
es, and are listed here in approximate order of
complexity. The details of using CAD software are
beyond the scope of this manual, but any of the
software above is a great place to start for anyone
interested in creating their own 3D models.
