Porous metal thin net structure forming process

The invention discloses a porous metal thin net structure forming process. The process comprises the following steps: S1, selecting a forming material; s2, porous metal thin net structures are formed in batches, specifically, multiple layers of thin net structures are arranged side by side, the edge parts are connected, and single-layer thin nets are separated layer by layer after the thin net structures are printed and formed as an integral structure; s3, setting process parameters: setting laser scanning speed, laser power, light spot diameter and layer thickness; the interval between the multiple layers of thin nets arranged side by side is more than three times of the diameter of a light spot; s4, heat treatment; and S5, chemical corrosion treatment. By means of the optimized forming process, the high-quality 3D printing porous metal thin net structure formed through selective laser melting can be prepared, the transparent effect can be adjusted at will according to changes of laser process parameters, an
