ASA 3D Printing
The outdoor specialist. UV-stable, weather-resistant, and tough enough for automotive and industrial applications.
Pedir OrçamentoWhat is ASA?
Acrylonitrile Styrene Acrylate (ASA) is an engineering thermoplastic designed for outdoor use. It maintains its color, strength, and dimensional stability when exposed to UV radiation, rain, and temperature cycling.
ASA is the industry standard for exterior automotive components, outdoor signage, and garden equipment. With a heat deflection temperature of 98°C and excellent UV stability, it outlasts PLA and PETG in demanding environments.

Frequently Asked Questions
How long does ASA last outdoors?
ASA maintains its properties for years of outdoor exposure. It shows minimal yellowing or embrittlement compared to ABS or PLA.
Is ASA stronger than ABS?
ASA has similar mechanical properties to ABS (~55 MPa tensile strength) but with dramatically better UV and weather resistance.
Can ASA be painted or post-processed?
Yes, ASA accepts paint well and can be vapor-smoothed with acetone for a glossy finish, similar to ABS.
What temperatures can ASA withstand?
ASA has a heat deflection temperature of 98°C, making it suitable for under-hood automotive applications and industrial environments.
Is ASA more expensive than PLA?
ASA is moderately more expensive than PLA due to the engineering-grade polymer. The added cost is justified for any outdoor or high-temperature application.
