Evaluation of fracture properties of 3D printed high impact polystyrene according to essential work of fracture: Effect of raster angle
The purpose of this work is to study the influence of different lay-ups on fracture properties
for high-impact polystyrene (HIPS) processed via material extrusion. The fracture properties
of 3D printed HIPS were studied based on the essential work of fracture (EWF). The
obtained data was in good agreement with the EWF criteria. Results showed that [− 45/45] 5
and [0] 5 lay-ups had the highest (10.855 KJ. m− 2) and lowest (1.6338 KJ. m− 2) resistance
to crack initiation (we) of 3D printed HIPS, respectively. Also, the highest and lowest value of …
