3devo Extruder
Filament width specifications
±0,1mm deviation is in spec:
Bad: < 2.75mm
In spec: 2.75mm
In spec: 2.85mm
In spec: 2.95mm
Bad: < 2.95mm
Switching materials
- let hopper run enpty for approximately 15 - 20 sec
- add little batches of material each time
- when the extrusion is pure, add more of the material
Shutting down
PLA can stay in extruder after shutting down. Other materials need to be flushed out (with purge material or PLA)
Dry filament
- 4-6 hours @70-80°C.
- Other sources say to stay below 40°C
Hydrate filament
- When the filament is too brittle
- Boil water in a large pot.
- Place a test piece of filament into the boiling water with tongs for 6 seconds.
- Allow the filament to dry completely (we recommend at least 24 hours). Do not dry the filament in direct sunlight.
- Test the re-hydrated filament with your 3D printer.
- If filament sizzles when printing, we recommend re-running the process, but only re-hydrate the filament for 2-3 seconds
- If the filament is still too brittle, run the process but re-hydrate for 10-12 seconds.
- Submerge the entire spool in boiling water for the same amount of time which worked for the test piece.
- Allow the spool to dry for at least 24 hours.
- Your filament roll is now hydrated and ready to use again.
