PLA printed by fused deposition modeling is polylactic acid filament melted in a heated nozzle and deposited bead by bead to build a part layer by layer. It is among the easiest filaments to print, adhering well to the build plate and warping little, so an enclosed heated chamber is not usually needed. Printed parts are anisotropic, weakest between layers where bead fusion governs strength, and they show visible layer lines and small voids between beads. Overhangs need supports that leave marks when removed. Typical uses are visual models, fit-check prototypes, jigs and fixtures, and lightly loaded housings, kept away from heat and sustained load because the material softens readily.
Anycubic PLA is a polylactic acid filament grade from Anycubic, extruded layer by layer by fused deposition modeling. Like other PLA printed this way, its parts are strongest along the deposited roads and weakest across layer interfaces. They show visible layer lines and some voids between beads, and they need removable supports under steep overhangs. PLA prints with little warping and needs no heated enclosure, but printed parts soften at relatively low temperatures and are poorly suited to warm or sustained-load service.
