Problems solved by technology

However, the above-mentioned patent uses ultraviolet light to cure the resin. One of its main disadvantages is that the reaction of photoreactive polymerization is limited, and there are more reactions that cannot be initiated by ultraviolet light, such as some non-free radical polycondensation reactions, molecular catalyzed reactions, and enzyme-catalyzed reactions. , thermal polymerization, cold polymerization, cationic polymerization, anionic polymerization, metal reduction synthesis, self-assembly, semiconductor material synthesis, inorganic material synthesis, etc., or purely physical phase change solidification

Abstract

The present invention relates to a point lattice technology 3D printing method and equipment applying the point lattice technology 3D printing method. According to the point lattice technology 3D printing method, the method is a continuous liquid interface synthesis method, and the curing reaction of a curing liquid is initiated in a point lattice manner to print. According to the present invention, the limitation of the application of the ultraviolet light initiation reaction can be overcome, and the ultraviolet light initiation reaction is replaced by the point lattice initiation, such that the material capable of being selected by the continuous liquid interface synthesis method is more, and the objects capable of being printed is more.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and relates to a 3D printing method using dot matrix technology and equipment using the same. Background technique [0002] Conventional additive 3D printing technology is built on a slow process of layer-by-layer printing. Construct three-dimensional objects in a step-by-step or layer-by-layer manner. Specifically, one layer is printed first, after drying or light curing, the resin is replenished and another layer is printed, and the above operations are repeated. New layers can form on top of old layers or on the underside. The disadvantages of this traditional 3D printing include slow speed, low fineness, defects, low mechanical strength and so on. [0003] Recently two companies / labs, Orange Maker Inc. and Carbon3D Inc. have developed a new 3D printing technology - continuous liquid interface synthesis (clip). The principle of this method is that the projector will continuously shoot ...
