Calibration method and system of 3D printing device and 3D printing method and device

Abstract

The invention discloses a calibration method and system of a 3D printing device and a 3D printing method and device. According to the calibration method and system of the 3D printing device and the 3Dprinting method and device, a plurality of energy radiation devices are arranged, so that the overall breadth of the energy radiation devices is increased; and the 3D printing device is calibrated, so that radiation energy of all positions in the overall breadth is balanced, the problem of edge joints caused by the plurality of energy radiation devices is avoided, and the printing quality is guaranteed while the breadth is increased.

Description

technical field

[0001] The present application relates to the field of 3D printing, in particular to a calibration method for 3D printing equipment, a calibration system for 3D printing equipment, a 3D printing method, and a 3D printing equipment. Background technique

[0002] At present, 3D printing is a kind of rapid prototyping technology. Specifically, it is based on digital model files, using powdered metal, plastic, resin and other materials that can be bonded or cured, to construct objects by layer-by-layer printing. During the 3D printing process, an energy radiation device is used to radiate energy to the printing reference plane, so that the printing material on the printing reference plane forms a solidified layer.

[0003] In some embodiments, the larger the format of the energy radiation device, the larger the number of objects and / or the area of ​​objects that can be manufactured simultaneously. However, affected by factors such as the manufacturing cost of th...
