PLA

Polylactic Acid
Visual prototypes · Production runs

PLA is the easiest, most printable plastic we offer. Sharp detail, low cost, and a wide color range — the default for visual prototypes and parts that won't endure heat or stress.

Strengths
& uses

The everyday choice for indoor parts. For rougher use, PLA Pro is the same material with five times the impact resistance.

Strengths
  • Sharp detail and dimensional accuracy
  • Low warp — large parts run reliably up to the full 500 mm bed
  • Available in dozens of colors
  • Cheap enough for production runs
Common applications
  • Visual prototypes
  • Architecture models
  • Lab fixtures and jigs
  • Educational models
