Polymaker ASA Filament 1.75mm Grey - Weather Resistant 1kg

In this review of the Polymaker ASA Filament 1.75mm Grey, the bottom line is straightforward: this filament is aimed at makers who need durable, weather-resistant prints for outdoor or functional parts. The reviewer found it most compelling for hobbyists printing RC parts, automotive trim, and outdoor fixtures because it combines ABS-like mechanical strength with added UV and environmental resistance. Print settings are familiar to ABS users, and the upgraded cardboard spool packaging is a welcome touch for those who prefer recyclable materials.

Key Features

• Weather resistant: UV resistance and reduced environmental stress cracking make it suitable for outdoor parts such as RC planes and car accessories.
• High heat resistance: Rated to withstand temperatures up to 100 C (212F), making printed parts less likely to deform in hot conditions.
• Mechanical toughness: Shares ABS-like toughness and impact resistance, so functional components hold up under load.
• Printer settings compatibility: Standard ABS-style settings (nozzle ~250 C, bed ~90 C) mean it prints predictably on many FDM machines, including enclosed setups for large items.
• Recycled cardboard spool: New packaging uses a fully recycled cardboard spool and box, reducing plastic waste from spools.

Who It's For

The filament is best for hobbyists and small shops that need reliable, outdoor-capable prints - think RC modelers, makers building outdoor mounts or housings, and anyone replacing ABS where UV exposure is a concern. It is also a good fit for users who prefer familiar ABS settings and want a filament that tolerates higher service temperatures.

Those who should look elsewhere include absolute beginners who are not comfortable tuning bed adhesion and warping, and users who require glass-like optical clarity or flexible materials, since ASA is a stiff, high-temperature thermoplastic rather than a clear or elastomeric filament.

Pros & Cons

Pros

• Good outdoor durability and UV resistance for long-lasting external parts.
• High heat tolerance up to 100 C for demanding functional applications.
• Prints well using standard ABS settings on many printers, delivering solid print quality.
• Recycled cardboard spool and box reduce packaging waste.

Cons

• Some users report mixed adhesion and occasional warping, so bed prep and an enclosed build chamber help for large parts.
• A few customers experienced filament breakage during prints, suggesting attention to storage and handling is needed.

Our Verdict

The Polymaker ASA 1.75mm Grey filament is a solid choice for users who need functional, weather-resistant parts with ABS-like strength. It provides good value when prints benefit from UV resistance and higher service temperatures, though successful results depend on proper bed adhesion and, for large pieces, an enclosed printer to limit warping.

Frequently Asked Questions

Will this filament work on a non-enclosed printer?
Yes for small parts, but for large models an enclosed printer is recommended to reduce warping and improve layer bonding.

What print temperatures should I use?
Start around 250 C for the nozzle and 90 C for the bed, and adjust slightly based on your machine and model size.

Is the spool recyclable?
Yes, the product ships on a fully recycled cardboard spool and box to reduce plastic waste.
