Method for removing jammed PLA filament from bowden tube

Recommended Posts

I recently had a bad jam in my bowden tube. After several material changes, the wispy threads that sometimes get left behind bunched up and wrapped around the filament I was using. It was so bad it created a visible bulge in the tube:

Normal methods for getting a broken piece of filament out of the tube were of no use, given how badly stuck this was. Here is what worked for unsticking a really bad (PLA) jam:

1. Remove all the loose filament you can

2. Remove the bowden tube from the printer

3. Boil water

4. Hold the tube under the hot water at the location of the jam for 2-3 minutes

5. Quickly insert a clean, room temperature length of filament into the tube

6. Use the clean filament to tap the jammed filament repeatedly until it comes out of the tube

7. Allow the bowden tube to air dry, then replace on the printer
