Example Embodiment
[0055] Example one:
[0056] 1) Use UG 3D modeling software to design the 3D model of the part, and output the STL file. Use the rapid prototyping post-processing software Magics to add the necessary support structure to the model, and slice and layer it. Import the processed data file into the SPS600B light-curing molding equipment to manufacture the shell of the part. The molding process parameters are set as follows: UV beam power is 250mW, filling scanning speed is 4500.00mm / s, filling vector spacing is 0.10mm, supporting scanning speed is 1200.00mm / s, jumping speed is 1200.00mm / s, contour scanning speed is 4000.00mm / s, The layer thickness is 70-100μm, the spot compensation diameter is 150μm, and the lifting speed of the worktable is 3.00mm / s. After the processing is finished, it is cleaned with industrial alcohol to remove the residual liquid resin material on the surface and remove the support. After being placed in an ultraviolet curing box for further curing, a resin mo...

[0064] Embodiment two:
[0065] 1) Use UG three-dimensional modeling software to design the three-dimensional model of the part, and then make the resin shell of the part by SLA light curing molding technology.
[0066] 2) Mix the organic monomer (acrylamide AM) and the crosslinking agent (N,N'-methylenebisacrylamide MBAM) at a mass ratio of 5:1, and then dissolve them to deionization at room temperature (25°C) In water, a water-based premix with a mass fraction of 15% is prepared. The mixture of micron silicon nitride and boron carbide and carbon fiber mixed powder in any proportion is slowly added to the dispersed water-based premix to obtain a ceramic slurry with a solid content of 10%. The addition of carbon fiber accounts for the total mass of the slurry 5%, and then add an aqueous solution of tetramethylammonium hydroxide with a mass fraction of 25% as a dispersant, and the added amount of the dispersant is 1.5% of the total mass of the ceramic powder to obtain a premixed sl...

[0072] Embodiment three:
[0073] 1) Use UG three-dimensional modeling software to design the three-dimensional model of the part, and then make the resin shell of the part by SLA light curing molding technology.
[0074] 2) Mix the organic monomer (acrylamide AM) and the crosslinking agent (N,N'-methylenebisacrylamide MBAM) at a mass ratio of 25:1, and then dissolve to deionization at room temperature (25°C) In water, a water-based premix with a mass fraction of 25% is prepared. Add micron-sized zirconium boride and carbon fiber mixed powder slowly to the dispersed water-based premix to obtain a ceramic slurry with a solid content of 45%. The addition of carbon fiber accounts for 25% of the total mass of the slurry, and then the mass fraction is added. A 25% tetramethylammonium hydroxide aqueous solution is used as a dispersant, and the addition amount of the dispersant is 2% of the total mass of the ceramic powder to obtain a premixed slurry. Then put the premixed slurry into a...
