Improved Mini Extruder: Layered Moineau based Pump

thingiverse

We've taken the performance of our "Layered Moineau Based Pump: Model 131313" to a new level, thanks to @SciFabLab - check it out at http://www.thingiverse.com/thing:1840527 for pumping viscous material in vertical direction with ease. See more details at https://osf.io/preprints/8yyms, and don't miss the video at https://www.youtube.com/watch?v=hEEVL4I48Rk. We've rounded up all layers to avoid flux loss due to high pressure inside the pump. The Layers form a cylinder that can be heated up when printed in metal - remember how we showed back in January 2017 that our multi-layer Moineau-based pump can easily extrude controlled quantities of viscous plastic PLA, perfect for RepRap 3D printers?
