Teeth marks on filament

Recommended Posts

I'm not having any issues printing, but I noticed that the filament ends up with teeth marks when it goes through the feeder. It's not grinding it or anything but it definitely has a continuous series of marks. Just wondering if this is normal?

I searched the forums but didn't find any information about it.

Look at the shaft that drives the filament up into the tube, it is knurled so that it can grip the filament. I assume that's what you're seeing. (and yes, it's normal)

 

Yes, it is knurled. Figured it didn't matter since my prints were coming out fine.

Thanks Robert! Btw, those two guides you made have been immensely helpful for this newbie. I owe you a few beers! :mrgreen:

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
