PolyLite ASA filament 1 kg, 1.75 mm

It is particularly suitable for outdoor housings, automotive components, brackets, garden components, functional prototypes, signs and mechanical parts exposed to sunlight and weather. ASA retains its colour and mechanical properties outdoors considerably better than standard ABS.

ASA and ABS have similar mechanical and thermal properties, but ASA is substantially more resistant to UV light and weathering. ASA is therefore the better choice for outdoor parts, while ABS is more suitable for applications without prolonged exposure to sunlight.

The recommended nozzle temperature is 240–260°C and the build plate temperature is 75–95°C. Polymaker's current profile supports speeds of up to 200 mm/s; a lower speed is preferable on older or slower printers.

Yes. Polymaker specifies an enclosure as a requirement for reliable ASA printing. An enclosure retains warm air around the part and reduces the temperature differences that cause warping and layer separation. These are also common problems when ASA is printed in an insufficiently warm chamber.

The main requirements are an enclosure, good first-layer adhesion and a disabled part cooling fan. A brim can also help considerably with larger models. Keep the chamber closed during printing and let the finished part cool gradually: rapid cooling increases internal stresses and can cause lifting or cracking.

Polymaker recommends textured PEI or a PC surface, with adhesive if required. Magigoo Original is a specifically recommended option for improving adhesion. A good first layer is critical for large parts because ASA shrinkage can place considerable force on the model's corners.

PolyLite™ ASA has a glass transition temperature of around 98°C, a Vicat softening temperature of around 105°C and an HDT of approximately 100°C at 1.8 MPa. This makes it considerably more suitable than standard PLA and PETG for functional parts used at elevated temperatures.
