Abstract (300 words maximum)

This work investigates the difference in impact response of traditionally extruded vs 3D printed Polyethylene Terephthalate Glycol (PETG) and High Impact Polystyrene (HIPS). The effect of a machined notch vs a 3D printed notch, the effect of the raster angle, and the role of percentage infill is also examined. IZOD impact energies at various temperatures ranging from -500C to 500C are experimentally obtained for 3D printed and extruded specimens. The specimens tested included 25% infill 3D printed with machined notch, 25% infill 3D printed with printed notch, 100% infill 3D printed machined notch, 100% infill with 3D printed notch, extruded with machined notch.
