The invention discloses a method for quickly obtaining standard forming parameters of a selective laser melting device, comprising: S1, designing a printing model of a test workpiece, wherein the test workpiece includes an inclined surface structure, a curved surface structure, a side through hole structure and a cantilever beam structure; S2. Print out n on the substrate according to the printing model 1 A test workpiece with the same shape, each test workpiece corresponds to a set of basic forming parameters; S3, detect each test workpiece, and obtain the corresponding inclined surface structural parameters, curved surface structural parameters, side through hole structural parameters and cantilever beam structure parameters; S4, according to the inclined surface structure parameters, curved surface structure parameters, side through hole structure parameters and cantilever beam structure parameters in step S3, obtain the standard forming parameters of the metal powder to be processed, the standard forming parameters include filling Forming parameters, upper surface standard forming parameters and lower surface standard forming parameters. The method of the invention has fast acquisition speed and strong directivity.
