Poly ethylene terephthalate PET is a commodity thermoplastic that is predominately used in drink bottles, production of which is forecasted to reach 583.3 billion in 2021. Waste PET plastic bottles also accumulate rapidly on Forward Operating Bases FOBs, and are currently disposed of by burning, which compromises the respiratory health of U.S. soldiers and residents of locales adjacent to FOBs. Fortunately, recycled PET rPET as well as its glass fiber GF reinforced composites have potential application as a cheap, local feedstock for fused filament fabrication FFF additive manufacturing AM, which could be used to fabricate repair parts on an FOB and thus reduce time required to obtain parts. The objectives of this study are i to explore the use of PET as a feedstock for FFF and ii to explore the effects of glass-fiber GF reinforcement on PET processability and final printed part properties.
