Uniaxial Tests of ABS/Elastomer Materials

1. Sample Collections

Dog-bone shape samples were printed with a 3D printer (LeapFrog Creatr) starting from a CAD model designed according the standard dimensions suggested by the ASTM D638. Samples were printed using different materials of different colours (e.g., ABS-red, ABS-green, ABS-white, and PLA-blue).

2. Mechanical testing

Uniaxial tensile test was performed using the MTS Insight Testing Systems, equipped by with a 10kN load-cell and with two wedge grips. The sample extension was measured using the ME-46 Video Extensometer. Uniaxial test was performed at the cross-head speed of 1 mm/min (and 5mm/min) until sample rupture.
