Purdue University Senior Capstone Group 11.2, began work on exploring the ability for thermoplastic polyurethane, specifically TPU 92A to be 3D printed on a fused deposition modeling (FDM) 3D printer. This work was started in conjunction with Los Alamos National Lab (LANL) in order to gain an understanding about the limitations and material properties of FDM 3D printing TPU 92A. The group decided on four material mechanical properties to use to be able to compare 3D printed material properties with extruded TPU. Mechanical Property testing included Tensile, Fatigue, Hardness, Bending, and Porosity. Testing revealed a significant difference between stock TPU and 3D printed TPU.
