Abstract

The invention relates to a 3D-printing-based tool for composite manufacturing of a fine structure and relates to the technical field of 3D printing equipment. The thought of composite manufacturing ofthe fine structure through laser selective melting on a traditional structural part is adopted, a manufacturing platform tool is designed, and fast clamping and locating of the tool are achieved. According to an original machining scheme, a substrate needs to be printed synchronously so as to meet the requirement of low forming efficiency of subsequent machining clamping, and the average printingtime of a single product is about two hours. The thought of composite manufacturing is adopted, a machining chuck is machined in place in advance and is installed on a special tool, thus printing ofthe machining chuck is avoided, printing time is reduced greatly, efficiency is improved, a chuck substrate can be reused, and manufacturing cost is reduced to a great extent.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a fine structure tooling based on 3D printing composite manufacturing. Background technique [0002] 3D printing technology is a technology based on the principle of discrete accumulation, integrated computer graphics processing, digital information and control, electromechanical control technology and material technology, and adopts the method of accumulating materials layer by layer to realize the technology of rapid free forming of parts. 3D printing technology can greatly reduce the complexity of product manufacturing and expand the scope of manufacturing. However, the efficiency and cost of laser selective melting for some key structural parts in aerospace and other fields still cannot meet the development needs of model products. Combining 3D printing with traditional manufacturing, it has become a trend to compound complex and fine structures on traditional c...
