may cause corrosion on internal metal part of extruding nozzle, if printer is heated for long time and
melted print filament is not extruded out, carbonized filament may easily block extruding nozzle, even
cause damage to extruding nozzle.

cleaned for long time, the whole extruding nozzle may be jammed with leftover filament, after being
heated for long time, dark stains can be seen, printing quality may be seriously affected; therefore,
suggest to clean extruding nozzle after model printing is completed each time, keep extruding nozzle
clean and avoid blocking.
Cleaning method: After model printing is completed, while temperature of extruding nozzle is still
high, hold a piece of clean cloth or soft napkins with tweezers or diagonal pliers, repeatedly mop
leftover filament until completely remove it. If temperature of extruding nozzle drops, reheat it to 200
℃
and continue.
