摘要

In the past, some studies have reported successful dual-material 3D printing (using the fused filament fabrication (FFF) process) of virgin thermoplastics that have differences in glass transition temperature (Tg). But hitherto, little has been reported on the 3D printing of primary (1°) recycled dual thermoplastics using the FFF process in line with sustainable development goals of the United Nations. This study reports the printing of 1° recycled acrylonitrile butadiene styrene (ABS) (Tg ≈ 105 °C) and polylactic acid (PLA) (Tg ≈ 45–55 °C) using the single nozzle FFF process. The best settings of FFF parameters for functional prototypes (tensile specimens per ASTM-D638) were reported for dual material printing (1° recycled ABS and PLA). The result suggested that the maximum peak load of 708 N was noticed for the samples printed at the nozzle temperature 210 °C for PLA and 260 °C for ABS, the printing speed of 60 mm/s, and the infill pattern triangular. The results are supported by the morphological analysis, i.e., scanning electron microscopy based photo micrograph, percentage porosity as per ASTM-B276, grain size no as per ASTM-E112, surface roughness (Ra), amplitude distribution function, bearing ratio curve, peak count, and 3D render images.
