Three-dimensional object printing method and device, storage medium and computer equipment

The invention provides a three-dimensional object printing method and device, a storage medium and computer equipment. The method comprises the steps that a powder material is provided to form a powder material layer with a first height; a liquid material is applied to the powder material layer according to layer printing data, a forming layer is formed, the forming layer comprises a patterned area and a non-patterned area, the patterned area has a second height, the second height is smaller than the first height, and the second height is the preset layer thickness; and the steps from the formation of the powder material layer to the formation of the forming layer are repeatedly executed, so that the obtained patterned areas of the forming layers are overlapped layer by layer to form a three-dimensional object. According to the three-dimensional object printing method and device, the storage medium and the computer equipment provided by the embodiment, the layer shrinkage problem caused by the reaction of a powder material and a liquid material can be compensated in advance, so that the height of the patterned areas of the formed forming layers meets the preset layer thickness, and the forming precision of the three-dimensional object is improved.
