Claim 1:
2. The 3D printing method according to claim 1, wherein the taking, by the controller of the 3D printing device, directions in which three sizes in the first size group are located as three printing directions of the object for printing comprises:
taking a direction in which a size, a value of which is minimum in the three sizes in the first size group, is located as a layer stacking direction of the object, a direction in which a size, a value of which is medium in the three sizes in the first size group, is located as a secondary printing direction of the object, and a direction in which a size, a value of which is maximum in the three sizes in the first size group, is located as a primary printing direction of the object for printing; or
the taking, by the controller of the 3D printing device, directions in which three sizes in the second size group are located as three printing directions of the object for printing comprises:
taking a direction in which a size, a value of which is minimum in the three sizes in the second size group, is located as a layer stacking direction of the object, a direction in which a size, a value of which is medium in the three sizes in the second size group, is located as a secondary printing direction of the object, and a direction in which a size, a value of which is maximum in the three sizes in the second size group, is located as a primary printing direction of the object for printing; or
the taking, by the controller of the 3D printing device, directions in which three sizes in the third size group are located as three printing directions of the object for printing comprises:
taking a direction in which a size, a value of which is minimum in the three sizes in the third size group, is located as a layer stacking direction of the object, a direction in which a size, a value of which is medium in the three sizes in the third size group, is located as a secondary printing direction of the object, and a direction in which a size, a value of which is maximum in the three sizes in the third size group, is located as a primary printing direction of the object for printing.
