Polymaker ASA is a 1.75 mm filament sold on 1 kg spools, formulated as an ABS alternative with much better UV and weather resistance. It keeps ABS-like strength and durability, so it suits functional parts, enclosures and prototypes that live outdoors. It prints with settings close to ABS and needs an enclosed printer to control warping. Against plain ABS it trades a little print familiarity for sunlight stability; against PETG it offers higher heat resistance but demands an enclosure and more careful ventilation.

Owners of Polymaker ASA generally report strong, UV-stable prints that hold up outdoors, with settings close enough to ABS to reuse existing profiles. Complaints center on warping on open printers and the usual ABS-style fumes and enclosure requirements.
Polymaker ASA is a 1.75 mm 3D printing filament made as an alternative to ABS. It offers improved weather resistance and UV stability, so it suits outdoor parts that are exposed to sunlight and the elements.
Its mechanical strength and durability are comparable to ABS. It is used for functional parts, enclosures and prototypes that need to hold up in real-world conditions.
It prints with settings very similar to ABS, so it is easy to switch to for users who already print with ABS. An enclosed 3D printer is recommended to control temperature and minimize warping.
