PLA Filament — PLA Filament Properties (Standard 1.75 & 2.85 mm)
PLA filament is the most widely used FDM 3D printing material. This page compiles the properties of standard PLA filament (1.75 mm and 2.85 mm) as shipped by mainstream brands (Prusament, Polymaker, MatterHackers, UltiMaker, Bambu Lab): density 1.24 g/cm³, tensile strength 50–60 MPa, tensile modulus 3.0–3.5 GPa, glass transition 60–65 °C, HDT 50–55 °C, shrinkage 0.2–0.5 %, print temperature 190–220 °C and bed temperature 0–60 °C. Low warping and clean surface finish make it the default choice for prototypes, models and cosmetic parts.
