Modal response of hybrid raster orientation on material extrusion printed acrylonitrile butadiene styrene and polyethylene terephthalate glycol under thermo-mechanical loads

In this paper we look at Acrylonitrile Butadiene Styrene (ABS) and Polyethylene Terephthalate Glycol (PETG), chosen for their low cost, high strength temperature resistance. This study evaluates the bending fatigue performance of Material extrusion (MEX) ABS PETG cantilever beams compares properties while varying a printing parameter under thermal loads. The study, using custom building orientation angles 90o, 45o 60o between layers, tested different temperatures from 30o to 50 °C. results show effects orientations on sample. orientation, which is same as loading, also slows crack growth.
