| Abstract: | In order to study the functional part from SLS processing with changing of mechanical properties, it analyzes the powder bed preheat temperature field of SLS forming machine, tests the tensile experiment for nine sinter speeimens under the different laser power based on the designed speeimen size, ealculates the elastic modulus value of nine specimens according to the statics tensile test data. Finally it derives the mathematical model between laser power of SLS forming machine and elastic modulus of sintered parts. |
