Following our work on "Layered Moineau based pump: Model 131313" by @SciFabLab -see: http://www.thingiverse.com/thing:1840527, we proudly present a fully functional prototype of a Mini Pellet Extruder that's remarkably easy to build, assemble and clean. This innovative device is designed for pumping a controlled quantity of viscous material in a vertical direction -check out the video at https://www.youtube.com/watch?v=Y3TjkRAStZk to see it in action! For more details, visit: https://osf.io/preprints/8yyms (be sure to check out our follow-up and improved version at http://www.thingiverse.com/thing:1915577). Note that depending on the rotation speed, you may need to apply a protective coating to all layers to prevent pressure-induced flux loss. Here's how to assemble it from bottom to top: 1st layer: - Use A1Nozzle.stl (or try using "A1Cover.stl" for an alternating flux effect) - Add A1Bottom.stl - Include sqr-axe.stl - Stack B1.stl on top 2nd layer: - Attach A3.stl - Stack B3.stl on top 3rd layer: - Use A1.stl - Stack B1.stl on top 4th layer: - Add A3.stl - Stack B3.stl on top 5th layer: - Use A1.stl - Stack B1.stl on top 6th layer: - Attach A3Top.stl - Top it off with B3Top.stl Complete the assembly by adding Tube_top_sqr.stl (or use "Tube_top.stl" as an alternative) Auger.stl (or try using "Auger-Cone.stl") Crank.stl Check out our Overview and Background section for more information. Mini Extruder: Layered Moineau based Pump plus Conical Auger This Mini Pellet Extruder is a game-changer - it's easy to build, assemble and clean, making it perfect for pumping a controlled quantity of viscous material in vertical direction.
