Problems solved by technology

[0003] During the SLM printing process, sometimes local support printing failures may occur, which will affect the subsequent forming of the part
Based on this problem, the general solution is to suspend printing and repair the support manually. On the one hand, the manual operation takes a relatively long time and the efficiency is low; risk of failure

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The present invention is a support automatic repair method based on additive manufacturing, the process of which is as follows figure 1 As shown, the principle is as figure 2 As shown, the specific steps are as follows:

[0028] Step 1, the support image of the printed layer is generated

[0029] Such as image 3 As shown, the camera 2 is set on the top of the forming chamber, and is electrically connected to the computer control system 1 through a cable. The camera 2 collects the printed image information of each layer support during the forming process and feeds it back to the computer control system 1, specifically:

[0030] When a layer of powder is laid and the printing of the current layer support is completed, the camera 2 collects the image of the printing layer and feeds the image information back to the computer control s...

Abstract

The invention discloses a support automatic repair method based on additive manufacturing, which is specifically implemented according to the following steps: step 1, the camera collects the printed image information of each layer of support in the forming process, and feeds back to the computer control system; step 2, the computer control system Identify whether the support printing of the current layer is normal, if there is a support printing failure area, extract the outline features of the printing failure area, and generate a repair path within the outline; step 3, call the repair path to repair and print the printing failure area. An automatic support repair method based on additive manufacturing of the present invention detects and recognizes in time when local support printing fails, and repairs it, shortens the forming cycle, improves printing efficiency, and can reduce the risk of part forming failure, further It can also reduce the labor cost in the production process.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and relates to a support automatic repair method based on additive manufacturing. Background technique [0002] With the continuous development of laser selective melting (SLM) forming technology, it is more and more urgent to use this process to form complex structural parts and its efficiency. Under normal circumstances, in the process of forming parts with complex structures, a grid support of a certain thickness is first added to the base material, and the part entity is formed on the support after the grid support is formed. The purpose of adding support is 1) to play a supporting role for the suspended part of the part or the area with a small angle; 2) to facilitate the diffusion of accumulated heat during the forming process of the part; 3) to play a role in the deformation of the part due to stress concentration during the forming process Tensile and protective effects, e...
