Printing Tips
- Pungent and unpleasant odors may be released during printing. Make sure your printer is placed in a well-ventilated area.
- Drying conditions: 80℃ for 8 hrs. Store in a dry environment after use. Dry before use if the material absorbs moisture. For more details please refer to: Filament drying instructions on WIKI.
- ASA is prone to warping when printing large size and/or high infill density model. To avoid warping: 1) Not recommemded to print too large size and/or high infill density models. 2) Use enclosure printers and ensure the build plate is properly glued before printing. 3) Set lower printing speed and higher heatbed temperature. For more details please refer to: Common print quality problems and solutions on WIKI.
- AMS lite NOT Compatible
- Enclosure Printers Required
