ABS or ASA?
| ABS | ASA | |
|---|---|---|
| Heat resistance | Good | Good |
| UV / weather | Poor — yellows and becomes brittle | Very good |
| Typical use | Indoor housings, car interiors | Outdoor housings, exterior trim, mounts |
If the part will see sunlight, choose ASA. Indoors, either works; we’ll confirm which in your quote.
Designing for ABS/ASA
- These materials shrink as they cool, so very large flat areas can warp. Ribs, fillets, and consistent wall thickness help.
- Sharp internal corners concentrate stress — add a fillet.
- Tell us about any mating parts so clearances are planned for.
Questions
Is ABS or ASA better for car parts?+
Both handle interior heat far better than PLA. For anything exposed to sunlight, such as dash-top or exterior parts, ASA is the better choice because it resists UV.
What temperature can ABS and ASA handle?+
Common grades begin to soften at around 95–100 °C. Real-world limits depend on load and geometry, so describe the environment in your request.
