Stringing problem in PETG 3D printing
Problembeschreibung
During PETG FDM 3D printing, stringing and hair-like thin filaments are produced when the nozzle moves.
Ursachenanalyse
Printing temperature is on the high side; melt viscosity is too low and thin filaments are drawn out; retraction parameters are set improperly, with insufficient retraction distance or speed.
Lösung
Reduce printing temperature to 220-235°C; increase retraction distance to 4-6mm and speed to 30-50mm/s; enable the wipe function.
Wichtigste Erkenntnis
PETG 3D printing stringing is solved by lowering temperature and optimizing retraction parameters.
