Embodiment 1
[0039] 100 parts by mass of polyacrylonitrile powder with a median particle size of 5 μm and 0.5 parts by mass of 50 nm silica were uniformly mixed, wherein the polyacrylonitrile powder came from pulverization.
[0040] Add the prepared 20kg powder raw material into the powder bin of the 3D printer, import the 3D solid figure of the desired product into the control computer, and then use the layering software to slice the 3D model; the 3D printer setting parameters are as follows: laser power 20W , the laser scanning speed is 500inch / s, the laser scanning spacing is 500μm, the thickness of the printed single layer is 50μm, the model filling rate is 30%, and the printing temperature is 100℃. The thermoplastic polymer powder is locally heated and sintered layer by layer to complete the green body preparation.
