Abstract

The invention discloses a three-dimensional object printing method, a data processing device and computer equipment. The invention provides a three-dimensional object printing method and a device thereof as well as computer equipment. The method comprises the following steps: acquiring first data of a three-dimensional digital model of a to-be-printed three-dimensional object, wherein the first data comprises shape data; acquiring geometrical characteristic information of the to-be-printed three-dimensional object according to the shape data, wherein the geometrical characteristic information comprises at least one of the angle of the surface, the sharpness of the ridge and the sharpness of the vertex in the to-be-printed three-dimensional object; determining second data of a supporting part for supporting the three-dimensional object according to the geometrical characteristic information, wherein the second data comprises extension width of the supporting part; and generating printing data according to the first data of the three-dimensional digital model and the second data of the supporting part, and printing based on the printing data to obtain a three-dimensional object comprising the extended supporting part. According to the three-dimensional object printing method provided by the embodiment of the invention, the supporting part can support the entity part of the three-dimensional object so as to prevent the three-dimensional object from being deformed due to the geometrical characteristic of the three-dimensional object; and the forming precision of the three-dimensional object is improved.

Description

technical field [0001] The present application relates to the technical field of three-dimensional object forming, in particular to a three-dimensional object printing method, a data processing device, and computer equipment. Background technique [0002] In the process of 3D printing, objects are solidified by layer-by-layer accumulation of printing materials. For some structures on the workpiece model, such as internal holes, cantilever beams, etc., if no support is added, these structures will collapse during the printing process, and even cannot be printed at the beginning. After the printing is completed, the support part usually needs to be removed. Therefore, in order to obtain a workpiece with a better surface weight, save printing materials and time, and improve economic benefits, the model support in 3D printing should be reduced as much as possible. [0003] However, reducing the use of the support part will lead to insufficient support force of the solid part th...
