Is this a dirty nozzle

Recommended Posts

Yes, I mean the two holes. There is one on the other side as well. I can't tell if they just appear as the filament stretches as I remove it, or maybe there is something in the nozzle. But I would expect if there was something in the nozzle, the holes would look like lines as I pulled the filament out over the obstruction. Or maybe it's voids in the filament? It is MatterHackers Pro Series PLA which I think is pretty good stuff. The outer surface of the filament is perfect.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
