English: Fatigue test of an additively manufactured specimen, showing final failure. This is a cyclic loading combining tensile and torsional applied forces. This shows the last few cycles after about 12000 loading cycles. The test is being conducted using an Instron Electropuls test system with pnuematic grips and a biaxial loadcell (force measurement device). The specimen is a hollow cylinder, manufactured from PLA, using a common filament extrusion machine.
