ASA filament is made for open 3D Printers that cannot print with ABS Filament. ASA Filament is stiffer, stronger, flexible UV resistant. It is designed for professional use. Most often it is used to produce prototypes, which must withstand higher temperatures. Finished products that are made of ASA filament are exceptionally durable and impact resistant. For superior results, you must print at a temperature of 240–260°C. For printing with an ASA filament, we recommend that the printer is closed, and the print bed should be heated to 100–120°C. Please note that the range in the printing temperature may slightly differ depending on the use of other printers.
