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.

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.

Description

technical field [0001] The present application relates to the technical field of three-dimensional object forming, and in particular to a method and device for additive manufacturing of three-dimensional objects, storage media, and computer equipment. Background technique [0002] The main process of the three-dimensional object additive manufacturing technology is to obtain the digital model of the three-dimensional object, slice and layer the digital model, and perform data processing and conversion on each slice layer to obtain the printing data of each slice layer. The printing device According to the printing data of the slice layer, the layer-by-layer printing is performed and superimposed to manufacture a three-dimensional object. [0003] The existing three-dimensional object additive manufacturing technology includes inkjet printing technology and powder and inkjet printing technology. Among them, inkjet printing technology mainly refers to the selective injection ...
