Direct Drive Pastruder
Description
This Is A Super-Simple Belt Driven Syringe-Based Extruder For Viscous Or Non-Newtonian Fluids Such As Peanut Butter. It Uses The Makerbot Mk6'S 100Oz-In Stepper Motor To Provide The Necessary Force, And Applies Pressure To The Syringe Via The Mechanical Advantage Of A Belt Based Reduction. This Potentially Also Increases The Resolutuon Of The Steps/Volume, But Very Little Experimentation Has Been Done With Fine Control Of The Flow Rate. This Model Was Designed Around Scraps I Happened To Have Laying Around, But It Works Really Well. This Extruder Was Co-Designed With Scott Beibin In July 2012, Specially For Use In The Groucho Fractal Show - Www.Grouchofractal.Com
