Currently trying to print a model with some bridging and I'm noticing a lot of random pieces of filament, even in locations where it isn't bridging. I'm using PETG and have made sure to dry it out for a good day before using. Any thoughts are appreciated!

Random pieces of filament could be due to several factors. Here are a few possible causes and solutions:

Heat: Ensure that the temperature of your hotend and bed is properly set for PETG. High heat can cause filament oozing and stringing. Try lowering the temperature slightly and see if it improves the bridging.
Retraction settings: Adjust your retraction settings. PETG generally requires less retraction compared to other filaments. Too much retraction can lead to stringing and blobbing. Experiment with different retraction distances and speeds to find the optimal settings.
Print speed: Reduce the print speed when working with PETG, especially when bridging. Slow down the speed to allow the material to cool and solidify before moving to the next section.
Cooling: Ensure your printer's cooling fan is properly cooling the print. Insufficient cooling can cause the filament to droop and string. Consider upgrading or adjusting the cooling fan to improve airflow.

Upon closer inspection, I am seeing some material stuck to the side of the nozzle while printing

Petg has a habit of stringing. I would run a bridge test and as per your latest comment make sure your hotend is not leaking

Thanks for the reply! How do I tell/what do I do about it?

Just switched to pla and am having the same issues. The PLA was working well last week when I last used it, so I'm not sure what the next step is to solving the issue

Heat up your hotend and manually extrude about 30mm (through the LCD Screen not by hand)
if it comes immediately then you have a partial clog (it should go down straight)

#

if you do have a partial clog, heat up your hotend and stick the needle that came with your printer up the nozzle all the way, then try extruding again and seeing if it comes down straight now

#

Other than that, like acetolyne said, PETG loves stringing, as well as curling and sticking to the nozzle
you should get a silicone sock on your hotend if you don't already have
and use lower printing temperatures to prevent oozing
and increase your fan speed to prevent curling (ofcourse with PETG you shouldnt increase your fan speed too much or it will cause very bad layer separation)
tune your retraction distance and retraction speed (PETG uses higher retraction distance than PLA and I believe can work with higher retraction speeds)
and should probably try to avoid travels when possible (for example cura's combing maybe, but also printing one model at a time if possible helps a lot)
