ASA 3D printing service
ASA is the plastic for anything that lives outside. It keeps its color and strength through years of sun, rain and heat, which makes it the standard choice for vehicle, marine and outdoor equipment parts.

What is ASA?
ASA (acrylonitrile styrene acrylate) was developed as a weatherproof alternative to ABS. It has similar strength and heat tolerance, but the sun does not yellow it or make it brittle. We print it in an enclosed, heated chamber so large parts come out flat and strongly bonded.
Design tips for ASA
- Use ASA whenever the part will sit in a parked car or in full sun.
- Walls of 1.6 mm or more keep large flat panels stiff.
- Add fillets where a wall meets a base; it prevents cracks under load.
- Tell us if a surface must be cosmetic and we will orient the part to suit.
Nozzles: 0.4 mm as standard, 0.2 mm for fine detail, 0.6 mm for larger parts printed faster. General tolerance is ±0.5% with a lower limit of ±0.5 mm. More in the design guide.

ASA 3D printing FAQ
Is ASA really UV resistant?
Yes. ASA was designed for outdoor use and is the material used for many factory exterior automotive parts. It keeps its color and strength in long-term sun, where PLA and PETG fade or soften.
Will an ASA part survive in a hot car?
Yes. ASA holds its shape to about 95–100 °C, well above the temperature inside a parked car in the desert Southwest.
ASA or ABS?
They are close in strength and heat tolerance. Choose ASA for anything outdoors or exposed to sun, and ABS for indoor parts where you want the lower price.
