| Abstract: | The polymer rapid prototype made by selective laser sintering (SLS) process could be burned out,so the metallic parts could be rapidly manufactured without moulds by combing casting process with SLS prototype. It is the precondition of rapid casting process to select polymer material that meet the case of both laser sintering and casting process. The characteristics of common polymer materials are compared and analyzed systematically, and the laser sintering experimentation of polymer material powder is carried out, in which polystyrene (PS) is selected to be the raw material of SLS prototype powder for rapid casting process. |
| Keywords: | Selective Laser Sintering (SLS) Polymer Rapid Casting Process Polystyrene |
