PLA Pro

Toughened Polylactic Acid
Functional prototypes · Production runs

PLA toughened to five times the impact resistance of standard, with the same sharp detail. It keeps PLA's low heat ceiling — when heat is the problem, the step up is PETG.

Strengths
& uses

Where standard PLA chips or cracks but a full engineering plastic is more than the job calls for.

Strengths
  • Charpy impact 13.44 kJ/m² — five times standard PLA's 2.68
  • Same sharp detail as PLA
  • More affordable than engineering-grade materials
  • Production-ready — reliable at volume runs
Common applications
  • Functional prototypes
  • Mechanical jigs
  • Indoor production runs
  • Indoor end-use parts
