I wanted to take a moment to call out some filaments I really like and that I’ve had good luck with. This is not meant to be an in-depth, exhaustive filament review. In the future, I may go into much greater detail on all the different types of filament, their strengths and weaknesses, specific brands I’ve had good/poor success with, etc. This is merely a quick list of those filaments I’m currently using and have had good luck with.
One of the issues I’ve had, particularly with PETG, has been plastic accumulating on the nozzle to the point where there is enough for it to come off the hotend and deposit itself on the part(s) being printed. The layer adhesion is so strong with PETG, these blobs attach themselves firmly enough to the part that the hotend carriage can be knocked off course when it tries to travel or print through the path where the blob has been deposited.
