Embodiment Construction
[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0029] In the prior art, although those skilled in the art usually preheat the powder layer before laser 2 scanning sintering to increase the temperature of the powder layer and reduce internal stress, those skilled in the art have not found that the edge of the forming cylinder is easy to dissipate heat and cause the cylinder The technical problem of low temperature in the edge area of the wall makes the cut surface after molding deform and warp when the part to be printed is located on the edge of the forming cylinder, which in turn causes the part to continue printing,...
