    How old are your printer, filament and slicer? Zits are common in adolescents.

    And now serously, if you look closely at how inconsistent your lines are, I would definitely look into the extruder. Maybe you have power issues, that could account for both printers having the same problem. If you suspect it’s the slicer, simply install another one and try.


  • I live in a dry climate. I don’t bother with PLA, but I dry PETG. I printed some stuff from a roll of PETG that had been open longer than a year, and looking closely at the melted plastic coming out of the nozzle, there was noticeable bubbles and stringing during printing. Once dried, all went away. People who claim you don’t need to dry some filaments must not care much about quality.
