This is a fairly new 0.4mm hardened nozzle in a Bambu P1S, the nozzle has maybe 100hrs on it with the only other filament being Overture PLA Pro Black. I switched to the Polymaker Metallic filament, got it calibrated, then printed 2 good parts. This handguard has since failed twice with the nozzle getting clogged. The longest part is the last print where it made it roughly 85% of the way and clogged before printing the threads...

This is my only spool of the material and I only have enough left for 1 more attempt, it's a nearly 18hr print. Is the Metallic glitter within the filament what's causing the clogs? Any tips or suggestions to avoid clogs with this material? Yesterday I took the extruder about and cleaned it well thinking that it could be contributing.

My poor X1C has suffered a lot through one hotend, including a lot of 20% CF PA6, 17% CF PET, and this plastic in gold, red, silver, and bronze, all of which comes out picture-perfect. If I had to guess, it's either wet or you have a clog.

Funny, I was actually JUST using the grey metallic for and invader build and had one of the worst clogs ever on my K1C. Need to replace my whole nozzle and thermistor now.

If it fails again in just saying screw it and going to do a 2 tone build lol. Sucks that ive wasted a good 1/3rd of a roll of the filament due to the clogs.

Maybe swap to a 0.6mm nozzle. Lots of filaments with additives (glitter, CF, etc..) like to clog up on 0.4.

Would i need to recalibrate the filament though for a 0.6mm? I have enough to redo the handguard with maybe 20g left on the spool.

You'd need to adjust your slicer at minimum. It's always a good idea to calibrate for all your nozzles though. Sounds like it's time to get some more filament regardless.

Thankfully and big props to polymaker, they gave me a coupon code to get another spool. I had $8 in credits to use and with the code I was able to order another 2 rolls for a whopping $0.20! 1000041364 1000041365

For the next spools ill try drying the filament longer and drying while printing just to fully rule out any possibility of moisture being the culprit but ill also get the 0.6mm calibrated for the filament.
