The invention discloses a
laser 3D printing and manufacturing method of an
electric spark electrode. The
laser 3D printing and manufacturing method comprises the following steps: (1)
machining and flattening a
metal base plate; (2) setting a
powder scraping amount of a scraper; (3)
cutting a 3D design drawing of the
electrode into multiple
layers of slice layer structures in the height direction;(4) adjusting printing parameters of a
laser device; (5) dividing each slice layer of the
electrode into multiple regions, and controlling
laser beams to perform overlapping scanning fusion covering in the regions covered with
powder; (6) performing scanning fusion covering on the first layer of the electrode on the
metal base plate, then repeatedly downwards moving the
metal base plate by one slice
layer thickness, and performing scanning fusion covering on the next layer of the electrode till the scanning fusion covering of the whole electrode is completed; (7) separating the metal base plate from the formed electrode to complete laser 3D printing and manufacturing of the
electric spark electrode. According to the laser 3D printing and manufacturing method of the
electric spark electrode, by use of a laser 3D printing technology, a metal-based material with a high content of
ceramic components is directly subjected to 3D printing to form the electric spark electrode with a complicated structure, so that no molds are needed; the working procedures are simple, the production efficiency is high, and the cost is low; the manufactured electrode can meet requirements of electric sparkmachining and electric spark deposition technologies.
