Introduction
What ASA is and when to use it
ASA behaves much like ABS — tough, heat-resistant and easy to post-process — but it was developed to withstand sunlight and weather. Where ABS yellows and turns brittle outdoors, ASA keeps its colour and properties far longer.
Like ABS, it shrinks as it cools, so we print it on our enclosed Bambu Lab P1S to keep the part warm and prevent warping and layer splitting.
Choose it when
- The part lives outdoors or in direct sunlight
- You need ABS-like heat resistance
- Colour stability matters over time
Avoid it when
- Indoor parts where PLA or PETG would do — they're simpler to print
- Very large flat parts with tight flatness requirements (ask us first)
