Planning to display 3D prints outdoors? Material choice makes the difference between a piece that lasts years and one that degrades in months. Here is how common filaments perform outside.
PETG: Best All-Around
PETG resists UV, moisture, and temperature extremes better than PLA while remaining easy to print. It handles Canadian winters and summers without becoming brittle or warping. Our top recommendation for garden decor.
ASA: Ultimate Weather Resistance
ASA was engineered for outdoor automotive parts. It offers the best UV stability of any common filament. Color retention is exceptional even after years of direct sun exposure. More challenging to print than PETG.
PLA: Indoor Only
PLA will degrade outdoors within 6-12 months. UV causes brittleness, heat causes warping, and moisture weakens layer adhesion. Beautiful for indoor display, not suitable for permanent outdoor placement.
ABS: Decent but Challenging
ABS performs reasonably outdoors but is difficult to print and releases fumes. PETG and ASA have largely replaced ABS for outdoor applications, offering better properties with easier printing.
Protective Treatments
Any outdoor print benefits from UV-resistant clear coating. Apply before outdoor placement and refresh annually. This simple step can double or triple the outdoor lifespan of PETG prints.
