Filamento de impresión 3D ASA - Guía completa para aplicaciones en exteriores resistentes a la intemperie [PRUEBA]

Last updated: April 21, 2026

ASA (Acrylonitrile Styrene Acrylate) is an engineering-grade thermoplastic filament designed for FDM 3D printing applications requiring superior weather and UV resistance. As the improved successor to ABS, ASA maintains excellent mechanical properties while eliminating ABS’s primary weakness—sensitivity to ultraviolet radiation. This makes ASA the material of choice for outdoor applications, automotive components, and any parts exposed to sunlight.

Key Properties of ASA Filament

ASA offers excellent UV resistance, maintaining properties under prolonged sunlight without yellowing. With impact strength of 14-20 kJ/m² (Charpy notched), it’s comparable to ABS in toughness. The heat deflection temperature reaches 95-105°C at 0.45 MPa, and water absorption is only 0.5-0.7%, lower than ABS. For precision parts, consider our Filamento PA6-CF with excellent dimensional stability.

ASA vs ABS: The Critical Difference

While both materials offer similar mechanical properties and printability, ASA provides superior UV resistance. ABS typically begins degrading within weeks of outdoor exposure, while ASA maintains its properties for years. For engineering applications, PA66-CF30 offers even higher strength with carbon fiber reinforcement.

Optimal Print Settings

Print ASA at 240-260°C nozzle temperature with a heated bed at 90-110°C. An enclosed print chamber is strongly recommended to minimize warping. Use 40-70 mm/s print speed and 30-50% cooling fan for optimal layer adhesion.

Aplicaciones

ASA is ideal for automotive exterior parts (mirror housings, trim, covers), outdoor equipment and garden tools, drone frames and RC vehicle components, signage and display items, and solar panel mounting hardware.

ASA 3D Printing Filament — Frequently Asked Questions

Is ASA better than ABS for outdoor 3D printing?

Yes, ASA provides superior UV resistance without yellowing. While ABS begins degrading within weeks of outdoor exposure, ASA maintains its color and mechanical properties for years. This makes ASA the ideal choice for outdoor applications including automotive exterior parts, garden equipment, and signage.

What temperature should I print ASA at?

Recommended nozzle temperature: 240-260C. Bed temperature: 90-110C with PEI or glass surface. An enclosed print chamber is strongly recommended to minimize warping. Print speed: 40-70 mm/s with 30-50% cooling fan for optimal layer adhesion.
