Abstract Scope |
Polyethylene Terephthalate (PET), a commonly used thermoplastic in plastic bottles, can be recycled for use in other applications. There are currently methods of recycling PET bottles for use in Fused Deposition Modeling (FDM) 3D printing, but these methods produce a filament that is often outside of the ideal specifications required for the tolerances of most FDM printers. Comparatively, the process of Fused Granular Fabrication (FGF) 3D printing requires looser tolerances compared to those of FDM printing. As a result, recycling PET bottles into printable pellets for use in an FGF printer would result in a more reliable, resilient printing of recycled PET bottles. The goal of this paper is to explore the ability to recycle and pelletize PET bottles for use in FGF 3D printing and compare the mechanical properties of the recycled PET bottle pellets to virgin PET pellets. |
