Sometimes persuading a new roll of filament to go through an extruder can be a bit of a pain. Here is how to quickly straighten and feed it.


Wave a lighter flame under the filament for a few seconds about 20mm from the end. Stretch the filament a bit while it is warm as shown - do not snap it as the end will then curl. Allow to cool, blow, or use burnt finger as heatsink.

Trim end to a stout point. This will now easily feed through most extruder mechanisms.

Been doing similar by heating the end and rounding it with my fingers Warning, afew degrees toohot and your fingers are joined with molten plastic

Umm, why didn't someone bring this up before? LOL

Awesomely simple, awesomely great

Take a Cutter and cut it at 60
° and it fits too :P

I dont get it? where is the fire?

Fire not show, to avoid igniting dining table. You just need to soften a patch of filament a little bit so you can stretch it out thin. Don't stretch it while it is in the flame, and don't melt it so so much it dribbles!


Also if you use M4 nuts to act as spacers between the idler bracket and the body of a Wade's extruder, so that it can't close up too far, then you can just push the filament in while it is running and it will grab it even with a flat end.
