[0030] Example 1
[0031] A method for preparing a 3D printing high-strength artificial stone pattern mold, comprising the following steps:
[0032] 1. Draw a CAD three-dimensional drawing according to the desired pattern. The gradient of the section of the pattern mold is 50° and the height is 10mm.
[0033] 2. Enter the CAD three-dimensional drawing drawn in step 1 into the 3D printer, and add 316L stainless steel powder into the material cavity, and the particle diameter is 15-45um.
[0034] 3. Adjust the flow rate of the powder to 10s / 50g, the moving speed to 2cm / s and the temperature of the laser beam to 1399-1455°C, and start printing.
[0035] 4. After printing, temper at 1000-1050°C to eliminate stress.
[0036] 5. Finally, perform surface treatment, grinding and polishing, the mesh number ranges from 800-5000 mesh, and finally obtain the 3D printed high-strength artificial stone pattern mold with a wall thickness of 1-2mm.
[0037] In the 3D printed high-strength ...
