Liquid cooled extruder revisited
I'm finally getting back to working on this- seems like it's been forever! I realized there were some problems with my previous liquid cooled extruder design so I designed a new version. The new extruder has a delrin liner and a removable nozzle similar to my original concept. The heater element is a simple power resistor but I'm going to try a vitreous enamel resistor in a small aluminum block as well.
