ASA (Acrylonitrile Styrene Acrylate) is the technical polymer of choice for outdoor applications: compared to ABS, it has excellent resistance to UV rays, atmospheric agents, and aging. It maintains color and mechanical performance for years even under intense sun, rain, and temperature variations.
When to use ASA
- Outdoor parts: roof, exposed to sun or weather.
- Automotive bodywork: grilles, moldings, exterior aesthetic parts.
- Helmets and protective parts: resistant to impacts and UV rays.
- Signs and signage: letters, logos, advertising supports.
- Drone and RC components: shells and external parts.
- Garden furniture and furnishing parts: that remain outdoors all year round.
Technical characteristics
- Nozzle temperature: 240-260 °C.
- Bed temperature: 90-110 °C.
- Heated chamber: highly recommended.
- Thermal resistance: 95-105 °C continuous.
- UV-resistance: superior (maintains color for 10+ years outdoors).
- Impact resistance: excellent, comparable to ABS.
- Chemical resistance: excellent to oils, greases, acids.

Frequently asked questions
ASA or PETG for outdoor use? ASA is better for prolonged UV resistance (years). PETG is suitable for moderate or seasonal exposure.
Difficult to print? Yes, like ABS it requires a heated chamber and well-calibrated parameters. Difficult for beginners.
Can I use it for outdoor safe boxes? Yes, it is one of the typical uses. It resists sun, rain, and frost.
How long does it resist the sun? Accelerated tests indicate over 10 years of UV exposure without significant loss of mechanical properties or color.
