| Abstract: |
| Based on the powder feeding 3D printer，using tensile strength as an index，the best molding process parameters of granular thermoplastic polyurethane elastomers were determined by the orthogonal test method as follows：barrel temperature 215 ℃，screw speed 8 r·min-1，nozzle temperature 230 ℃，and print platform temperature 45 ℃. The best molding process parameters were verified by printing tire and honeycomb model. |
