Polylactic acid (PLA) is a thermoplastic derived from renewable resources. Safe for the office, this material is non-toxic and easy-to-print with high reliability and dimensional accuracy. MakerBot precision PLA Material is optimized with the slicing algorithm in software to give you the best results and highest quality. Ideal for the early stages of concept modelling and form studies, PLA printed objects will generally have a glossier look and feel. The filament smells delightful while printing and can be printed on a cold surface as well. Allows you to create objects with minute details.
