3D printing file generation method and device, computer equipment and storage medium

Abstract

The invention relates to a 3D printing file generation method and device, computer equipment and a storage medium. The method comprises the following steps that 1, all suspended faces in a to-be-printed model are obtained; 2, printing paths of corresponding supporting areas are determined according to the suspended faces, and the printing speeds of the supporting areas are set, so that the supporting areas are continuously cooled and formed when being printed along the printing paths at the printing speeds of the supporting areas; 3, the supporting areas are in a suspended state and are used for preventing the corresponding suspended faces from sinking during printing; and 4, a printing file is generated according to the printing path of the supporting areas with the set printing speed and each layer of slice of the to-be-printed model. Due to the fact that the supporting areas can be continuously cooled and formed during printing at the set printing speed, the probability of sinking of the supporting areas is reduced, the probability of sinking of the corresponding suspended faces supported by the supporting areas is reduced; and due to the fact that the supporting areas are in the suspended state, the supporting size is reduced, a material consumed by a support is reduced, and the printing speed is improved.

Description

technical field [0001] The present application relates to the technical field of 3D printing, in particular to a 3D printing file generation method, device, computer equipment and storage medium. Background technique [0002] Driven by the intellectualization of computer digital technology, the application of three-dimensional (3D) printing technology is becoming more and more extensive. 3D printing is to first slice the model and generate a slice file, and then print layer by layer according to the slice file. Bonding materials to create three-dimensional objects. Due to the diversity of the model, some positions of the model will be suspended, that is, the lower part of some positions is unsupported, and the unsupported position may sink when printing, so it is usually necessary to add support for the suspended position; currently added The method of support is to generate vertical support from the point where the support needs to be added on the model to the bottom of th...

Problems solved by technology

Due to the diversity of the model, some positions of the model will be suspended, that is, the lower part of some positions is unsupported, and the unsupported position may sink when printing, so it is usually necessary to add support for the suspended position; currently added The method of support is to generate vertical support from the point where the support needs to be added on the model to the bottom of the workspace or the position on the model below the point where the support needs to be added, but this generates more supports, which affects the printing speed and waste of printing materials
