FusRock FusFun ASA Filament


FusFun™️ ASA Filament has excellent all-round properties, featuring minimal odor and UV resistance. It is an alternative to ABS filaments due to its similar physical and mechanical properties with ABS. FusFunTM ASA is not sensitive to moisture. Once the sealed packaging is open, there is no need for moisture-proof measures. FusFreeTM S-Multi Quick-Remove Support Material is a good support material for FusFunTM ASA, and it solves the question of poor support surface quality when FusFunTM ASA works as a self-support material.

Printing Tips: 1. Compared with PLA and PETG filaments, ASA/ABS needs a higher environment temperature to release the residual stress during printing. Please keep the chamber closed to avoid warping and layer separation issues during the process. If your printer has a heated enclosure already, please keep the chamber temperature between 60-80°C. 2. If you find the printing quality decreases after ASA has been exposed in the air for a long time, please dry the filament at 70-80°C for 4-6h.
