Method and device for determining support data of three-dimensional model and electronic equipment

The invention discloses a method and a device for determining support data of a three-dimensional model and electronic equipment. The method comprises the steps that a three-dimensional model is obtained, the three-dimensional model is located in a voxel space formed by an X axis, a Y axis and a Z axis, and the voxel space comprises a plurality of voxels; determining a target source voxel from the plurality of voxels; determining a target secondary voxel corresponding to the target source voxel in the negative direction of the Z axis; performing voxel type judgment on the target secondary voxel, and determining a voxel type result of the target secondary voxel; and obtaining support data corresponding to the three-dimensional model according to the voxel type result. The technical problem that the supporting condition of the printed three-dimensional model is unstable when the three-dimensional model is printed according to the three-dimensional printing data including the supporting data in the related techn
