FATIGUE TEST AND WEAR ASSESSMENT ON 3D PRINTED SPECIMENS

A displacement-controlled fatigue test was performed to evaluate the wear of 3D printed TPU (thermoplastic polyurethane) cubes with gyroid structure.

The goal was to test the long-term integrity of additively manufactured specimens by analyzing their response in terms of maximum and minimum loads.

The test has been carried out by the ProtoLab members B. Rossetti and L. Montaldo using a LiTeM fatigue testing machine  available at the Department of Civil Engineering and Architecture (DICAR) of Pavia University.  The research activity has been supervised and designed by G. Alaimo, S. Marconi and F. Auricchio.

Specimens were subjected to compression cyclic test, deforming them within a range of 10mm to 50mm at a frequency of 2 Hz, for a total number of 150’000 cycles.
