Polymaker PF01023 ASA filament

Polymaker™ ASA is a weather-resistant 3D printing filament from Polymaker, designed as a direct alternative to ABS with significantly improved UV stability and outdoor durability.

It offers mechanical strength comparable to ABS while resisting degradation from sunlight, moisture, and temperature fluctuations — making it the preferred choice for functional outdoor parts.

Prints with similar settings to ABS and produces a matte surface finish that helps conceal layer lines.

Note:This product is being renamed from PolyLite™ ASA to Polymaker™ ASA.

Same great formula, new name.

Key Features.

Superior UV resistance and outdoor weatherability compared to ABS.

Mechanical properties comparable to ABS — strong, rigid, and impact resistant.

Heat resistance up to 105°C.

Water resistant and suitable for outdoor applications.

Prints with similar settings to ABS — easy transition for ABS users.

Matte surface finish that minimises visible layer lines.

Can be post-processed with acetone for smooth surfaces Polymaker™ ASA - Weather-Resistant Filament for Outdoor and Functional Parts.

Polymaker™ ASA is Polymaker´s outdoor-grade filament, engineered as a direct alternative to ABS with one key advantage:significantly better resistance to UV light, moisture, and environmental stress.

It is the material of choice for parts that need to perform reliably outdoors over extended periods — without fading, cracking, or losing mechanical integrity.

UV Resistance and Weather Durability.

ASA was developed specifically to overcome ABS´s weakness to UV exposure.

In natural aging tests, Polymaker™ ASA showed a color change value (ΔE) below 2.5 after two years of outdoor exposure.

In accelerated aging tests under 8000 kJ/m² irradiation, color change remained below ΔE 5 with minimal tensile strength loss — performance that clearly surpasses ABS.

Parts printed with Polymaker™ ASA are documented to maintain structural integrity for a minimum of two years under outdoor conditions including sunlight, rain, and temperature fluctuations.

Mechanical Properties.

Polymaker™ ASA delivers mechanical strength and rigidity comparable to ABS, making it suitable for functional parts, housings, enclosures, and prototypes that need to withstand real-world stress.

Heat resistance reaches up to 105°C, and the material also offers good impact resistance and water resistance — a well-rounded profile for demanding applications.

Printing Behaviour.

Polymaker™ ASA prints with settings very similar to ABS, making it a straightforward transition for users already familiar with ABS workflows.

An enclosed printer is recommended to maintain chamber temperature and minimise warping, particularly for larger prints.

The cooling fan should be kept off during printing.

The material produces a matte surface finish that visually softens layer lines compared to ABS.

For larger prints (parts exceeding approximately 15-20 cm in any direction), an actively heated chamber of 70°C or more is recommended for best results.

Bed adhesion products such as Magigoo Original or BuildTak can help with larger prints.

Print Settings.

Printing temperature:240°C - 260°C.

Bed temperature:75°C - 95°C.

Printing speed:30-50 mm/s.

Cooling fan:Off.

Direct drive retraction:1 mm / 20 mm/s.

Bowden retraction:3 mm / 40 mm/s.

Handling and Storage.

ASA is partially hygroscopic and will absorb moisture if left unprotected.

If the filament has been exposed to humid conditions, drying at 70°C for 6 hours is recommended before printing.

Humidity-controlled storage is advised for long-term storage.

Post-Processing.

Polymaker™ ASA can be smoothed with acetone, similarly to ABS.

Acetone is a hazardous chemical — handle with appropriate safety precautions and in a well-ventilated area.

Typical Applications.

Outdoor enclosures, housings, and brackets.

Automotive exterior parts and accessories.

Garden and agricultural equipment components.

Functional prototypes requiring UV and weather resistance.

Parts requiring UV sterilisation compatibility
