AnyCubic ASA Filament White 1 kg — 3D printer filament (ASA) for FDM printing

AnyCubic ASA Filament White 1 kg is a 1.75 mm thermoplastic filament supplied on a 1 kg spool with approximately 395 m of material. It is formulated for FDM 3D printing and designed for demanding applications, especially outdoor use. ASA offers improved weather and UV resistance compared with common filaments, a high heat deflection temperature up to 90°C, and lower odor during printing than ABS.

Advantages

ASA provides long-term UV and moisture resistance, good dimensional stability at elevated temperatures, and notable mechanical strength. The filament combines high impact resistance and stiffness with relatively low odor during extrusion, making it suitable for functional parts exposed to sunlight and changing weather.

Suitable for

• Outdoor enclosures and housings
• Functional prototypes and mechanical parts
• Signs, fixtures, and items exposed to sunlight
• Applications requiring higher heat deflection than PLA or PETG

When it may not be suitable

ASA can be more demanding to print than PLA: it typically requires a heated bed, higher nozzle temperatures, and good part cooling control to avoid warping. It may also require ventilation or an enclosure to manage layer adhesion and surface finish. For purely aesthetic indoor models or beginner-friendly prints where low-temperature printing is preferred, PLA or PETG may be more convenient.

How to use

Load the 1.75 mm AnyCubic ASA filament into an FDM printer that supports ASA. Recommended starting settings are a print nozzle temperature in the ASA range (typically higher than PLA), a heated bed to reduce warping, and moderate print speed. Use an enclosed build chamber or ensure good bed adhesion (brims, rafts, or adhesive surfaces) for larger parts. Provide adequate ventilation during printing to reduce fumes and monitor first layers for correct adhesion.

What to consider before purchase

• Ensure your printer supports ASA and 1.75 mm filament
• Plan for a heated bed and possibly an enclosure to reduce warping
• Verify required nozzle and bed temperature ranges for ASA
• Consider ventilation needs if printing indoors

Usage recommendations

For best results print with a heated bed, consider an enclosure to stabilise ambient temperature, use adhesion aids for the first layer, and allow parts to cool gradually to minimise internal stresses. Adjust print speed and fan settings according to part geometry to balance surface quality and strength.
