Roughness of the filament

Recommended Posts

Hi guys. I'm new to 3D printing. I just bought an ultimaker 2 extended+. As my filament goes into the feeder it tends to get rough like a scaly appearance instead of how smooth it was previously. Could I please have some help here if there is anything I should be worried about or to avoid it? Thank you guys in advance.

Hi and welcome ;)

This is caused by the knurled wheel in the feeder, it has to grip the filament to make it move so it will always leave some marks on the filament.

As long as it doesn't get flattened or grinded you should be perfectly fine.

Do you have any issues with the printer?

    • 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.
