The use of thermoplastic polyurethane composites to develop a model of the renal pelvicalyceal system by 3D printing
Abstract
Composites based on thermoplastic polyurethanes (TPUR) were obtained using the twin-screw extrusion method. Influence of the addition of 6, 7 and 8 wt% silica and 1–3 wt%. aluminum oxide and 1–3 wt%. dibutyl phthalate (plasticizer) on Rockwell hardness, Charpy impact strength and tensile mechanical properties was tested. The best properties were obtained for a composite containing 8 wt% silica, 3 wt% aluminum oxide and 3 wt% dibutyl phthalates. For this composite, the renal pelvicalyceal system was obtained using the FFF method.
