Wade's Extruder

Wade's Extruder

This work is based on Adrian's Geared Nema 14 extruder design, and includes many concepts lifted from Nophead's extruder research. This extruder was designed for the RepRap Mendel (but will work on a Darwin or Huxley with adaptors) and is robust, provides a strong force to extrude, is cheap and DIY. It is an alternative to the standard extruder for RepRap Mendel 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 M3 tap; no need to make splines on motor shaft;

I started working on the extruder but after trying to make it work decided to try Wade's Geared Extruder

To do

• (calibrate temperature)
• (calibrate speed)
• (update Firmware)
• (print new base for extruder)
• (Try it)

Current Situation

• 2012/10/04 - Printed all parts, bought a new motor and assembled the Extruder
• Instead of using plastic I used bamboo in the hot end. I think it works well. You can read more at this page
• Now need to calibrate the temperature and speed. Using a 100K Thermistor for the temperature sensor.
