SUNLU filamento ASA 1,75 mm nero – bobina da 1 kg per stampa 3D

Engineered with excellent UV resistance and low shrinkage, SUNLU ASA filament delivers reliable, functional 3D prints that withstand outdoor conditions and mechanical stress.

Overview

This ASA (Acrylonitrile Styrene Acrylate) filament is a robust alternative to ABS, offering improved weather resistance and a matte black finish. With a diameter of 1.75mm and a tolerance of ±0.02mm, it ensures consistent extrusion and high-quality surface detail. The 1kg spool is vacuum-sealed with desiccant to maintain optimal dryness, ready for professional and hobbyist applications.

What stands out

• Excellent UV and weather resistance prevents fading and degradation
• Low shrinkage compared to ABS, reducing warping during printing
• High tensile strength and stiffness for durable end-use parts
• Consistent 1.75mm diameter with tight tolerance
