Document Type and Number:
WIPO Patent Application WO/2022/033112
Kind Code:
A1
Abstract:
Provided are a three-dimensional object additive manufacturing method and device, a storage medium, and a computer apparatus. The method comprises: forming a powder material layer by using a powder material; applying a liquid material on the powder material layer according to layer printing data, the liquid material dissolving at least part of the powder material, the liquid material comprising an active component capable of polymerization; and providing energy to the powder material layer, such that the active component in the liquid material polymerizes, the powder material itself does not polymerize and does not polymerize with the active component, and a region in the powder material layer where the liquid material is applied is formed to obtain a sliced layer of a three-dimensional object. The three-dimensional object additive manufacturing method and device, the storage medium, and the computer apparatus provided can effectively improve the mechanical strength of a three-dimensional object, reduce the porosity of the three-dimensional object, and increase the density of the three-dimensional object.
