Embodiment 1
[0043] The steps of the present invention are:
[0044] 1) Raw material preparation
[0045] ZrO with a particle size of 0.1-10 μm 2 After pretreatment, put them into the feeding barrel in the feeder; put the ABS resin into another feeding barrel in the feeder;
[0046] 2) modeling
[0047] First use computer modeling software to model, and then "partition" the built 3D model into sections with a thickness of 20μm, that is, slices, so as to guide the printer to print layer by layer;
[0048] 3) Calculate the ratio
[0049] According to the compositional design requirements of the polymer-based gradient material, calculate the ratio of inorganic substances and organic polymers at different positions of the gradient structure, and input it into the computer as a variable to control the powder feeding ratio at different positions during printing;
[0050] 4) Set print parameters
[0051] Set the printing speed to 0.05m / s, the printing resolution to 20μm, and the powder feedi...
Embodiment 2
[0056] The steps of the present invention are:
[0057] 1) Raw material preparation
[0058] Put the SiC component with a particle size of 0.5 μm into the feeding barrel in the feeder after pretreatment; put the polylactic acid resin into another feeding barrel in the feeder;
[0059] 2) modeling
[0060] First use computer modeling software to model, and then "partition" the built 3D model into sections with a thickness of 50 μm, that is, slices, so as to guide the printer to print layer by layer;
[0061] 3) Calculate the ratio
[0062]According to the compositional design requirements of the polymer-based gradient material, calculate the ratio of inorganic substances and organic polymers at different positions of the gradient structure, and input it into the computer as a variable to control the powder feeding ratio at different positions during printing;
[0063] 4) Set print parameters
[0064] Set the printing speed to 0.1m / s, the printing resolution to 50μm, and the...
Embodiment 3
[0069] The steps of the present invention are:
[0070] 1) Raw material preparation

[0072] 2) modeling
[0073] First use computer modeling software to model, and then "partition" the built 3D model into sections with a thickness of 100μm, that is, slices, so as to guide the printer to print layer by layer;
[0074] 3) Calculate the ratio
[0075] According to the compositional design requirements of the polymer-based gradient material, calculate the ratio of inorganic substances and organic polymers at different positions of the gradient structure, and input it into the computer as a variable to control the powder feeding ratio at different positions during printing;
[0076] 4) Set print parameters
[0077] Set the printing speed to 0.2m / s, the printing resolution to 100μm, and the powder fe...
