PLA - 3.00 mm

Polylactic acid or polylactide (PLA) is the most commonly used desktop 3D printing filaments.  PLA is an easy material to print with for the entry level RepRapper.  It is odourless, low-warp, and does not require a heated bed. PLA is also one of the more eco-friendly 3D printer materials available; it is made from annually renewable resources (corn-starch) and requires less energy to process compared to traditional (petroleum-based) plastics.
