Extruder Modifications
The syringe extruder was based off the RepRapPro Paste Extruder design (Licensed under the GPL; all files available from the RepRapPro Ltd Github repository at https://github.com/reprappro/Paste-extruder). The syringe-based extruder designed in this project is made up of printed parts, non-printed parts, and electronic components. Figure 2 below shows the full syringe-based extruder, including 6 parts printed directly from the RepRapPro Extruder design (available online). The part labelled “MOUNTING BRACKET” was custom designed and 3D printed. The extruder was assembled as per instructions given on the RepRapPro website[L1].
