The effects of layers orientation on impact energy evaluation of FDM printed specimens

This paper investigates the effects of layers orientation on impact energy absorbed by acrylonitrile butadiene styrene (ABS) test specimens, obtained additive manufacturing (AM), having three in-plane deposition directions (0°, 45°, and 90°). The specimens were tested with instrumented Charpy hammer, CEAST 9050 Pendulum Impact System, according to standard ISO179-1. Unnotched in edgewise direction based measured velocity force; was computed. average during tests for at 45° about 0.39 J. For those layer 0° 90°, respectively, it 0.63 0.81 A hinge break failure mode observed 90° brittle fracture specimens.
