Direct granules extruder version 2
A first video showing the extruder in action
I am still evolving the design, so for now just a quick look at the componentsFigure 1:
The main idea is to have a machine that can turn waste plastics into granules and from that into something useful like a constructional element if you are an engineer or a sculpture if you are an artist.
The Extruder replaces the hotend of my Zonestar QR2, the frame, stepper mount and gears are 3D printed.
This is a quick look at all the internal components. As you can see, its hand made with a conventional screw as core element. Looks simple and that what it is, but before I got here I had to see many similar versions fail over the past months the hackaday prize was running.

Stringing is an issue of the extruder version shown here, but only minor changes can eliminate that, as I have seen in previous iterations of my designs - I will show that in coming videos and test prints.
