Baby it's cold outside

Well actually unlike the song, it's rather mild for a Toronto December. There's also no snow on the ground =(

Semantics aside, the cold end is nearing completion!

In this picture again is the overall shot of the printer. Main addition is the backplate holding the extruder cold end.


















closeup of the cold end. As mentioned in David's post, it's similar to a Wade style extruder with a delrin plunger. The things missing are obviously the gears (which have to be ordered from Misumi and are darn expensive) the hobnobbed M8 shaft, and the delrin plunger.









Final shot is the back of the machine, showing the spots where the gears are secured (the dangling wire is from the z axis motor).













till next time,

Eric
