| Abstract: | The relationship between the density and the static strength of SLS specimen, and the effect of adhensive content of sinterde powder, laser power, beam speed, scan space and scanning path on the specimen bending strength have been studied in this paper. Also, the cause of bending deformation in sintering has beenanalyzed. The bending strength of sintering specimen has been tested by three-point bending experiment. |
