PLA Filament

Price: $.06 per gram (including rafts & supports)

We use MakerBot PLA filament for all of our 3D printing. Polylactic acid (PLA) filament is “a nontoxic resin made of sugar derived from starches found in foods, like potatoes, corn, grain, or even beets.” PLA filament is also compostable and recyclable in a #7 recycling center. (Source: MakerBot)

All files are printed with a 10% infill by default.

  • Any 3D drafting software may be used to create a design as long as the file can be saved in .stl or .obj file format. We recommend Tinkercad or SketchUp Free which are free web-based programs.
  • Tinkercad and SketchUp Free may be accessed from any computer with an internet connection.
  • Digital designs also are available from various file-sharing databases such as Thingiverse, MyMiniFactory, and Pinshape.
