Polymaker ASA Filament 1.75mm Blue, 1kg - Weather Resistant Outdoor

In this review the Polymaker PolyLite ASA 1.75mm blue filament is assessed as a practical choice for makers who need durable outdoor parts. The bottom line: it is best for functional prints that require UV and weather resistance, with mechanical strength similar to ABS. The reviewer found it prints well on standard ABS settings and benefits from a recycled cardboard spool, though users should expect to tune adhesion and cooling to reduce occasional warping on larger pieces.

Key Features

• Weather resistant: UV-resistant formulation reduces environmental stress cracking, making prints more reliable outdoors.
• High heat tolerance: Rated to withstand temperatures up to 100 C, suitable for components that see elevated temperatures.
• ABS-like mechanics: Offers the toughness and impact resistance of ABS while adding improved outdoor durability for functional parts.
• Recycled packaging: Ships on a fully recycled cardboard spool and box, reducing plastic waste in storage and handling.
• Printer settings guidance: Recommended nozzle 250 C, bed 90 C and 50mm/s print speed help users get a reliable starting point for tuning.
• Support available: Lifetime technical support is offered to help troubleshoot printing issues and dial in settings.

Who It's For

This filament suits hobbyists and small shops printing functional outdoor parts such as RC model components, car accessories, housings and brackets that need UV and weather resistance. It is a strong option when toughness and heat tolerance matter more than a glossy finish.

Users who need perfect cosmetic surfaces for display models or who cannot use an enclosed printer for large ABS-like prints should consider other PLA-like or specialty filaments that are easier to print with on open printers. Beginners may need some trial and error to get adhesion and warping under control.

Pros & Cons

Pros

• Consistently prints well using standard ABS settings on many desktop machines.
• Good mechanical strength and impact resistance for functional parts.
• Improved UV and weather resistance extends the lifespan of outdoor prints.
• Environmentally friendlier packaging on a recycled cardboard spool.

Cons

• Can show adhesion and warping issues on large parts if not printed in an enclosure or without proper bed prep.
• Some users report inconsistent part strength, so tuning extrusion and cooling may be required for best results.
