Development. Wade's Geared Extruder. Wade's Geared Extruder Release status: Working This work is based on Adrian's Geared Nema 14 extruder (Adrian's Geared Extruder) design, and includes many concepts lifted from Nophead's extruder (Nophead's Extruder Tweaks) research.
This extruder was designed for the RepRap Sells Mendel (but will work with about any 3D printer, if with adaptors) and is robust, provides a strong force to extrude, is cheap and DIY. It is an alternative to the Geared Nema17 Extruder Driver and has the following advantages: no need to buy/use expensive metal gears; no need to do two precision flats on motor shaft; no need to glue the PTFE barrel; Other advantages over other extruders are: extrude/print at high speed; good for use with a low torque/cheap Nema 17 motor ; (Needs verification) no need to use expensive and complex tools - just one hand drill, a file and a M4 or M5 tap; no need to make splines on motor shaft; How to get it Mechanical Construction Materials Printed Parts Non-Printed Parts 3D CAD Files.
