Filament BambuLab ASA 1.75 mm 1 kg with reusable spool — Gray

BambuLab ASA 1.75 mm filament in gray is a 1 kg spool of ASA material supplied on a reusable spool for FDM/FFF 3D printers that accept 1.75 mm filament. The filament is formulated for outdoor use, offering resistance to weathering and UV exposure while maintaining mechanical strength and dimensional stability. It is intended for parts that require better environmental durability than standard PLA or ABS, and it is suitable for functional prototypes, housings and external components where sustained performance in changing conditions is needed.

Advantages

This ASA filament provides enhanced UV and weather resistance compared with common thermoplastics, reducing discoloration and surface degradation over time. It offers good mechanical strength and dimensional stability, enabling reliable fit and function for printed parts. The material is supplied on a reusable spool that simplifies storage and handling, and the consistent diameter and quality control support steady extrusion and predictable print results.

Suitable for

• Outdoor enclosures and housings exposed to sunlight and moisture
• Functional prototypes and mechanical parts requiring durability
• Architectural models and external fixtures
• Tooling aids, jigs and fixtures used in production environments

Key specifications

• Material: ASA (Acrylonitrile Styrene Acrylate)
• Diameter: 1.75 mm nominal
• Spool weight: 1 kg net filament
• Color: Gray
• Packaging: Reusable spool for filament storage and handling

How to use

Load the 1.75 mm filament into a compatible FDM/FFF 3D printer according to the printer manufacturer’s feeding and loading procedure. Use print settings appropriate for ASA, typically higher nozzle and bed temperatures than PLA; consult your printer and slicer for recommended temperature ranges and cooling settings. Ensure good bed adhesion using a suitable build surface or adhesive and consider an enclosed build area to reduce warping. Trim or anneal printed parts as needed following standard post-processing practices for ASA.

Usage recommendations

For best outdoor durability, orient parts to minimize stress concentrations and apply a UV-resistant coating if prolonged color stability is critical. Store the filament on the reusable spool in a dry environment or sealed bag with desiccant to maintain print performance.
