Embodiment 1
[0038] refer to Figure 1 to Figure 3 As shown, a laser sintering printer includes a frame 3, an upper cylinder body 2, a lower cylinder body 5, a workbench 17, a powder spreading powder supply mechanism 23, an orientation guide rail 11, a lead screw nut pair 12 and a telescopic structure 4; The upper and lower cylinder bodies are connected to the telescopic structure 4 through fitting, so that the entire molding cylinder is a closed space; the workbench 17 is fixedly connected to the inside of the lower cylinder body 5 by welding.
[0039] In order to realize 3D printing work, the screw nut pair 12 is located at the center of the bottom end of the lower cylinder body 5, which is consistent with the Z-axis direction of the forming cylinder body; Lead screw nut pair 12 makes lower cylinder body 5 do the orientation guide rail 11 of lifting motion.
[0040] In this embodiment, the directional guide rail 11 includes a slider 8 and a static guide rail 7, and the static guide rail...
Embodiment 2
[0055] The difference between this embodiment and Example 1 is that the diameter of the powder outlet holes on the powder outlet sieve is 70um, the number of powder outlet holes on the powder outlet sieve is 2300, and the screw powder feeding mechanism and the powder outlet The gap between the insides of the powder supply and powder sets is 0.2mm; the purpose of this design is to adapt to the particle size of the powder. If the particle size of the powder is below 70um, the powder outlet sieve will filter the powder with a diameter greater than 70um, because in 3D printing Among them, the diameter of the powder that does not meet the requirements will reduce the printing quality; the powder output can be adjusted to adapt to the small area of the workbench and improve the efficiency of powder supply.
[0056] The working mode and other structures and connection modes of this embodiment are the same as those in Embodiment 1.
Embodiment 3
[0058] The difference between this embodiment and embodiment 1 is that the diameter of the powder outlet holes on the powder outlet sieve is 120um, the number of powder outlet holes on the powder outlet sieve is 546, and the screw powder feeding mechanism and the powder outlet The gap between the insides of the powder supply and powder sets is 0.1mm; its purpose is consistent with that described in Example 3, that is, if the particle size of the powder is below 120um, the powder outlet sieve will filter powders with a diameter greater than 120um, because in 3D printing , The diameter of the powder that does not meet the requirements will reduce the printing quality; the powder output can be adjusted to adapt to a large-area workbench and improve the efficiency of powder supply.
