Preliminary Testing to Determine the Best Process Parameters for Polymer Laser Sintering of a New Polypropylene Polymeric Material
Table 3
The process parameters used to build different standard tensile specimens (ASTM D 638).
| | Specimen | Temp. of the removal chamber (°C) | Temp. of the building chamber (°C) | Layer thickness (mm) | Hatch distance (mm) | Scanning speed fill (mm/s) | Laser power fill (W) | Scanning speed contour/edges (mm/s) | Laser power contour/edges (W) |
| | 1 | 125 | 125 | 0.15 | 0.25 | 2000 | 23.3 | 700 | 9.7 | | 2 | 125 | 125 | 0.15 | 0.25 | 2500 | 25.5 | 700 | 13.0 | | 3 | 125 | 125 | 0.15 | 0.25 | 2500 | 30.2 | 700 | 13.0 | | 4 | 125 | 125 | 0.15 | 0.25 | 3500 | 31.5 | 1500 | 10.7 | | 5 | 125 | 125 | 0.15 | 0.25 | 4500 | 34.7 | 1500 | 21.3 |
