Yesterday I finally started assembling my extruder that will be mounted on one of my mills.
It’s uses a stepper with a gear box to control flow rather than a dc motor that uses pressure like a Makerbot.
-Plastruder ~ $180.00
-A few pounds of material to work with. I got some black and some orange.
It’s actually pretty satisfying bolting these plastic chunks together with springs, ball bearings and bolts. I can’t wait to be making this sort of stuff.
