Polymaker ASA Filament 1.75mm Purple - Weather Resistant Outdoor

In this review of the Polymaker PolyLite ASA filament the bottom line is clear: this spool is aimed at makers who need durable, weather-resistant parts for outdoor use. The purple 1.75mm 1kg roll blends the toughness and print behavior of ABS with improved UV resistance and reduced environmental stress cracking, so it is best when you need functional parts like RC plane components, car accessories, or other exterior fixtures. It prints using standard ABS-style settings and comes on a recycled cardboard spool, which is a practical plus.

Key Features

• Weather resistant: UV-resistant formulation reduces fading and environmental stress cracking for longer outdoor life.
• High heat resistance: Rated to withstand temperatures up to 100 C (212F), so parts tolerate warm conditions and some engine-heat exposure.
• ABS-like mechanics: Shares toughness and impact resistance with ABS, making it suitable for functional, load-bearing prints.
• Recycled spool: Upgraded 3.0 packaging uses a fully recycled cardboard spool and box to reduce plastic waste.
• Printer settings: Recommended nozzle 250 C, bed 90 C, and print speed 50 mm/s, which works with common ABS profiles and enclosed printers.

Who It's For

This filament is best for hobbyists and small workshops that print outdoor functional parts-think RC modelers, DIY auto modders, and anyone needing tougher, UV-stable components. It is particularly convenient for users running printers capable of higher nozzle and bed temperatures and for those who can print in an enclosure for large items.

If you primarily print decorative models, very fine detail miniatures, or do not have a heated bed or enclosure, you might look to PLA or specialty engineering filaments instead; ASA requires slightly more attention to adhesion and cooling management than low-temperature filaments.

Pros & Cons

Pros

• Good outdoor durability thanks to UV resistance and resistance to environmental stress cracking.
• High heat tolerance and impact resistance make it suitable for functional, load-bearing parts.
• Prints well using standard ABS settings on many printers and works with common slicer profiles.
• Sustainable packaging with a recycled cardboard spool cuts down on plastic waste.

Cons

• Some users report mixed adhesion and occasional warping, so an enclosed printer or brim may be necessary for large parts.
• A few reports of filament breakage during printing suggest that spool handling and printer feed should be checked if issues occur.

Frequently Asked Questions

Do I need an enclosure to print this filament?
An enclosure is recommended for large parts to reduce warping, though small parts can print successfully with careful bed adhesion and temperature control.

What slicer settings should I start with?
Begin with nozzle 250 C, bed 90 C, and about 50 mm/s print speed, then adjust cooling and flow as needed to match your printer.

Is this filament suitable for outdoor RC parts?
Yes. Its UV resistance and improved environmental stress cracking performance make it well suited for outdoor RC components and automotive accessories.
