The invention provides a parallel metal three-dimensional printing forming method based on induction melting, which comprises the following steps: preparing CAD data files of three-dimensional printing forming parts, forming substrates, metal powder and metal powder induction melting forming array plates; Filling the closed outline figure of each layer of slices in an inner part in a block way; The metal powder is controlled to flow out through the powder feeding nozzle, and then is rapidly heated and melted by the induction coil, so that the formed metal liquid drops almost vertically impact the current molding surface of the molding substrate, namely, fall into the small blocks filled in blocks and level in the small blocks, and then solidify into a whole with the current molding surface, so that the corresponding small blocks increase a certain thickness; According to this method, the molded parts can be stacked from bottom to top. According to the invention, the array board is formed by metal powder induction melting, and the area array projection type powder is formed in parallel by spray, so that any single layer is formed by spray at one time, and the forming speed is greatly improved in quantity compared with the traditional method.
