Improved Mini Extruder: Layered Moineau based Pump by encan

Last crawled date: 3 years ago

We have improved the performance of our on "Layered Moineau based pump: Model 131313" by @SciFabLab -see: http://www.thingiverse.com/thing:1840527 for pumping a controlled quantity of viscous material in vertical direction.
See more details at: https://osf.io/preprints/8yyms (see also video at https://www.youtube.com/watch?v=hEEVL4I48Rk)
We have rounded up all layers to avoid any flux lost due to the induced high pressure inside the pump. The Layers form a cylinder (that may be heated up when printed in metal) -we have recently shown (Jan 2017) how our multi-layer Moineau-based pump can easily extrude a controlled quantity of viscous plastic PLA, which could be used in RepRap 3D printers -see YouTube video: https://www.youtube.com/watch?v=KVAJQfXY_PE

(**) B.stl put it such that you cover one hole of ABottom)

(2nd layer)
A.stl put 2 holes perpendicular to ABottom (*)
B.stl put opposite to B (*) (twisted by 180 degree)

(3rd layer)
A.stl put 2 holes perpendicular to previous A
B.stl put apposite to previous B

(4th layer)
A.stl put 2 holes perpendicular to previous A
B.stl put opposite to previous B

(5th layer)
A.stl put 2 holes perpendicular to previous A
B.stl put opposite to previous B

(6th layer)
A.stl put 2 holes perpendicular to previous A (stator 450 degree)
BTop.stl put opposite to previous B (you complete the rotor spiral)
