PLA (FDM, Bambu Lab Bambu PLA Basic, annealed)

Bambu Lab Bambu PLA Basic in the annealed condition is a PLA filament grade printed by fused deposition modeling and heat-treated after printing. As printed, parts have a layered structure of fused extruded roads with visible layer lines and some voids between roads, are weaker across layers than along them, and need support under overhangs. Annealing crystallizes the largely amorphous as-printed polymer and raises its heat resistance, but it also causes shrinkage and can distort thin or unevenly supported features, so dimensions need compensation. Annealed parts are used for fixtures, jigs, housings and functional prototypes that must keep their shape at moderately elevated temperatures. Every value on this page is read from Bambu Lab's own material data sheet — quoted, cited and dated — and is the maker's statement about printed material, not a measurement by MatWorld; none has yet been reviewed by a person.
