The invention provides a three-dimensional model data processing method and a 3D printing method and system. The data processing method comprises the steps that a three-dimensional model is placed ina first calibrated breadth face or a second calibrated breadth face on the basis of the first calibrated breadth face of a first energy radiation system in 3D printing equipment and the second calibrated breadth face of a second energy radiation system in the 3D printing equipment; and the intersection exists between the first calibrated breadth face and the second calibrated breadth face. The small-breadth-face three-dimensional model is placed in one calibrated breadth face of the 3D printing equipment including the multiple energy radiation systems, manufacturing can be conducted through one energy radiation system even when part of or all arranging positions of the three-dimensional model are located in the intersection area, and accordingly, the opportunity for manufacturing three-dimensional objects through single energy radiation systems can be improved.
Description
technical field [0001] The present application relates to the field of 3D printing, in particular to a data processing method for a 3D model, a 3D printing method and a system. Background technique [0002] 3D printing technology is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal, plastic and resin to construct objects by layer-by-layer printing. 3D printing equipment manufactures 3D objects by performing this type of printing technology. 3D printing equipment is widely used in molds, customized products, medical fixtures, prostheses and other fields due to its high molding precision. Among them, the 3D printing device based on layer-by-layer printing stacks and attaches multiple cross-sectional layers according to the 3D model to form a corresponding 3D object. Since this type of 3D printing equipment is not limited by molds, flexible in manufacturing, and precise in layer thicknes...
