Filament oozing refers to when excess melted filament leaks out of the hot end nozzle, often leaving small strings or blobs on the printed part. Oozing is caused by filament continuing to extrude from the nozzle even when it is not actively extruding plastic for the print.
I ran into this little problem while printing with matte PLA. Share the solution.
Firstly slow down printing speed, which gives filament more time to solidify. Ensure the hot end assembly is tight, wobble can exacerbate oozing issues. Printing at the lowest effective temperature for the filament can reduce oozing. Tuning retraction settings can also help reduce oozing.
