Printing Atomic Filament ASA
Atomic Filament ASA in Black runs on the ASA profile below, and this listing is a 1kg spool. ASA is best suited to UV-stable outdoor parts that need to survive sun and weather without yellowing. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.
Ranges checked against Bambu Lab, Prusament and Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our ABS & ASA filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.
Nozzle Compatibility
This is an unfilled plastic, so it is not abrasive: a brass nozzle works and lasts, and so does hardened steel. With hardened steel, print about 5 to 10°C hotter.
Based on Bambu Lab and Prusa guidance. More in our nozzle types guide.
