Decorative prints are forgiving. Functional parts — ones that bear load, take heat, or live outdoors — aren't. Here's how to pick.
Needs to be tough
PETG is the easy upgrade from PLA for everyday functional parts. For higher strength and wear resistance, step up to PA6 Nylon.
Needs to take heat
PC+ Polycarbonate handles temperatures well beyond PLA and PETG, making it ideal for parts near motors, engines, or sunlight.
Needs to live outdoors
ASA resists UV and weather without yellowing — the go-to for outdoor fixtures and automotive parts.
Needs to flex
TPU 95A bends and absorbs impact — perfect for gaskets, grips, and protective cases.
Needs stiffness without weight
Carbon-fiber blends like PLA CF and PETG CF add rigidity and a premium matte finish.
