Embodiment 1
[0027] The operation process and parameters of the spatial grid printing method of a 3D printing sand mold are as follows:
[0028] The size of the sand mold is 800mm×800mm, the height is 150mm, and the upper part is an arc surface structure of R=500mm, such as figure 1 shown.
[0029] The first step is to leave a solid wall thickness of 80 mm at the sand mold boundary according to the size of the sand mold, and divide the rest of the space into grids. Use a sphere with a diameter of 6 mm to divide the inner space of the sand mold into each sphere space grid cavity, and each sphere space A gap of 2mm is left between the grid cavities as the support part of the sand mold (see figure 2 ).
[0030] The second step is to import the sand mold 3D entity into the computer of the 3D printing equipment.
[0031] The third step is to use 3D printing to complete the sand mold.
[0032] The fourth step is to bake and heat the sand mold (3 hours at 150°C). After the baking is complet...

[0036] The operation process and parameters of the spatial grid printing method of a 3D printing sand mold are as follows:
[0037] The size of the sand mold is 800mm×800mm, the height is 150mm, and the upper part is an arc surface structure of R=500mm, such as figure 1 shown.
[0038] The first step is to leave a solid wall thickness of 80 mm at the sand mold boundary according to the size of the sand mold, and divide the rest of the space into a grid. Use a cube with a diameter of 6 mm to divide the inner space of the sand mold into each square space grid cavity, and each cube space A gap of 2mm is left between the grid cavities as the support part of the sand mold (see image 3 ).
[0039] The second step is to import the sand mold 3D entity into the computer of the 3D printing equipment.
[0040] The third step is to use 3D printing to complete the sand mold.
[0041] The fourth step is to bake and heat the sand mold (3 hours at 150°C). After the baking is completed, ...
Embodiment 3
[0045] The operation process and parameters of the spatial grid printing method of a 3D printing sand mold are as follows:
[0046] The size of the sand mold is 800mm×800mm, the height is 150mm, and the upper part is an arc surface structure of R=500mm, such as figure 1 shown.
[0047] The first step is to leave a solid wall thickness of 80 mm at the sand mold boundary according to the size of the sand mold, and divide the rest of the space into grids, using a cube grid whose circumscribed ball diameter decreases from 4 mm to 0.2 mm for each layer. Arranged radially from large to small, the internal space of the sand mold is divided into gradient grids of different sizes. (see Figure 4 ).
[0048] The second step is to import the sand mold 3D entity into the computer of the 3D printing equipment.
[0049] The third step is to use 3D printing to complete the sand mold.
[0050] The fourth step is to bake and heat the sand mold (3 hours at 150°C). After the baking is comp...
