Hi guys,

I made water cooled extruder units.

My 3D printer is too small and therefore I didn't use traditional long aluminium air cooled extruder.

Does the pumping action have any effects on the printing quality?

I don't see any advantages for printing quality.

If you're going to print ABS inside a heated chamber, water cooling the extruder makes sense because the ambient air temperature may not be low enough to prevent heat creep up the throat of the extruder. I print ABS in a 45-50C enclosure using air cooling and it works, but maybe the OP is planning on a warmer temperature. Stratasys prints ABS inside a 70C oven.

Or like he said, the extruder is too small for air cooling...
