PLA
Polylactic Acid
Fast-printing thermoplastic with tight dimensional accuracy and clean surface finish. 52 °C HDT limits thermal applications, but low warping and high stiffness make it our everyday workhorse — production runs of dimensionally critical parts, visual models, and assemblies that need a smooth as-printed finish without post-processing.
