Polymaker ASA Filament 1.75mm Black + White, 2kg - Weather Resistant

In this review the Polymaker PolyLite ASA filament is evaluated for hobbyists and makers who need outdoor-ready, functional 3D prints. The bottom line: it is best for users who want a filament with ABS-like strength but improved UV and weather resistance, making it a strong choice for parts exposed to sun and moisture. The spool pair (black and white, 2kg total) is practical for testing and short production runs, and the included printing settings provide a clear starting point for reliable results.

Key Features

• Weather resistance: UV-resistant formulation reduces environmental stress cracking and helps parts last longer outdoors.
• High heat tolerance: Material withstands temperatures up to 100 C (212F), useful for parts exposed to higher ambient or operating heat.
• ABS-like mechanicals: Toughness and impact resistance mirror ABS, so functional components and structural prints perform well.
• Cardboard spool packaging: Recycled cardboard spool and box reduce plastic waste and make storage lighter and easier to recycle.
• Clear print settings: Recommended nozzle 250 C, bed 90 C and 50 mm/s print speed give a straightforward starting point for dialing in prints.

Who It's For

This filament is aimed at makers printing functional outdoor parts such as RC plane components, car accessories and housings that need UV resistance and higher heat tolerance. Users with enclosed printers or those who can manage warping with a heated bed will get the best results, especially for larger parts.

It is less appropriate for beginners who cannot control bed adhesion or for those seeking a flexible aesthetic filament; some users report mixed adhesion and occasional warping, so users who need near-zero tuning effort may prefer PLA alternatives for purely decorative prints.

Pros & Cons

Pros

• Good outdoor longevity due to UV resistance and reduced environmental stress cracking.
• High heat resistance and ABS-like strength suit functional and mechanical parts.
• Eco-friendlier packaging with a fully recycled cardboard spool and box.
• Works with generic ABS settings and prints well on many setups, including Bambu-type printers noted by users.

Cons

• Some users experience inconsistent adhesion and occasional warping, so tuning may be required for reliable large parts.
• A few reports of filament breaking during printing suggest quality can vary between spools or require careful handling.

Our Verdict

The Polymaker PolyLite ASA 1.75 mm dual-color pack is a solid, value-minded choice for anyone printing functional outdoor parts that need UV and heat resistance. It delivers ABS-like toughness with improved weather performance and recyclable packaging, but larger or critical parts may require tuning for adhesion and to avoid warping.

Frequently Asked Questions

Is this filament suitable for outdoor use?
Yes, the ASA formulation is UV-resistant and less prone to environmental stress cracking, making it suitable for outdoor functional parts.

What print settings should I start with?
Begin with a 250 C nozzle, 90 C bed and around 50 mm/s print speed; adjust per printer and use an enclosed build for large pieces.

Is the packaging recyclable?
Yes, the spool and box use fully recycled cardboard as part of the upgraded packaging.
