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].
