So you went to sleep with your 3D printer running. Excitedly, you wake up and run to go take a look at your beautiful new creation. To your dismay, something has gone horribly wrong. You’ve had a failed 3D print. It didn’t just create a fresh plate of filament spaghetti, but it has fully encased the hot end of your extruder in a PLA / PETG blob.
We’ve been there -- the racing heart, the panic, the fear your 3D printer will never run again. While it is possible you’ve damaged the 3D printer, it’s more likely you can get everything back to normal working order by following these steps. The most important part in 3D print clean up is to stay cool and don’t rush. Damage is more often caused by frustration and impatience when trying to pull off the cold hardened PLA / PETG blob with force than by the print failure itself.
