Abstract
The behavior of triply periodic minimal surfaces (TPMS) structures like Gyroid, Schwarz P and Schwarz D created by using the Rhinoceros 6 software was studied through experimental mechanical compression testing. The topologies were printed using additive manufacturing and the DLP technique in cubic volumes, having dimensions of 25x25x25 mm. They had different unit cell arrangements ranging from one unit cell and going up to 8x8x8 unit cells. The overall weight of the samples was kept approximately constant as the increase of cells number would not affect the weight for each topology. Cubes were subjected to static compression testing and elastic constants were established by using the digital image correlation (DIC) method. Failure patterns have been studied by analyzing the cells’ collapse in compression.
