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

Abstract

The invention provides a three-dimensional object additive manufacturing method and device, a storage medium and computer equipment. The method comprises the following steps of forming a powder material layer by using a powder material; applying a liquid material to the powder material layer according to layer print data, wherein the liquid material is dissolved to part of powder material and comprises an active component capable of performing a polymerization reaction; and providing energy to the powder material layer, wherein the active component in the liquid material is subjected to the polymerization reaction, the powder material itself is not subjected to polymerization reaction and is not subjected to polymerization reaction to the active component, and an area where the liquid material is applied to the powder material layer is formed to obtain a section layer of the three-dimensional object. According to the three-dimensional object additive manufacturing method and device, the storage medium and the computer equipment, the mechanical strength of the three-dimensional object can be improved effectively, the porosity of the three-dimensional object can be reduced effectively, and the compactness of the three-dimensional object can be improved effectively.

Problems solved by technology

However, this molding method has a relatively narrow range of material selection, and the exposure to chemical reactions can easily lead to a porous structure in the slice layer, and because the powder material participates in chemical reactions, it is easy to reduce the molding accuracy due to uneven reactions.
