We met up last night to work on the extruder. We have been using the natural HDPE and the results are good. The material is much stronger and flexible compared to when we were just using the HDPE colorant. Our motor is still under powered but instead of buying a new motor just yet, we are going to try gearing it down. A 2:1 reduction will double our torque and half our speed. The gears will be 3D printed (not sure if they will be strong enough but its an easy test) and we will use the same motor. Our extrusion speed will go down but at least we will have some results.
We also cleaned up some space for the company and our project. Check out the pictures https://osprintingllc.com/2012/11/27/new-project-space/
