We recommend cutting up strands (say 20cm) and loading that through the printer when changing between materials.
- 1. Before printing and after printing to clean the extruder.
- 2. Prevent nozzle plugging during transition between filaments with different melt point.
- 3. Prevent nozzle plugging during transition between filament with different print performance.
- 4. Clean the extruder during transition between filament with different color.
- 5. Perfect for most of materials including PLA, ABS, PETG, etc.
