Mid-Atlantic Section Fall Conference
As part of an undergraduate research project, a study was undertaken to determine the feasibility of extruding recyclable plastic into usable filament to create a sustainable technology for 3-D printing. An extrusion process was developed using PETG pellets to create a baseline that would be used when incorporating recyclable plastics. Modifications were done to allow for higher temperature extrusion to accommodate the higher melting temperature of PET plastics. A method of drying the plastic prior to extrusion was determined to be a necessary factor in the extrusion process. The viscosity of the PET plastic was determined to be a valuable characteristic that affects the possibility of creating filament. From this study, a conclusion can be made that there are multiple key factors that will determine the feasibility of extruding recyclable plastics into filament.
