This work brings an evaluation of the use of post-consumer poly(ethylene terephthalate) (PET) as a feedstock for additive manufacturing in fused deposition modeling from the comparison among five different filaments used. Three filaments were produced by reactive extrusion of post-consumer PET and different amounts of the chain extensor pyromellitic dianhydride (PMDA), 0%, 0,3% and 0,5%, and two commercial filaments of recycled PET and glycol-modified PET (PETG) were acquired. The five filaments were characterized by melt flow index, differential scanning calorimetry, thermogravimetric analysis and Fourier-transform infrared spectroscopy. The printed specimens were characterized by superficial rugosity, dimensional accuracy, x-ray diffracti...
