Grating preparation method based on 3D printing and 3D printing equipment

The embodiment of the invention provides a grating preparation method based on 3D printing and 3D printing equipment, and the method comprises the steps: firstly obtaining the structural parameters of a target grating, and generating a processing path model of the target grating based on the structural parameters of the target grating and printing parameters corresponding to the 3D printing equipment, and the target grating can be prepared according to the processing path model of the target grating. Through the mode of automatically preparing the target grating according to the generated processing path model, the preparation defects of poor regularity, poor roughness, low depth-to-width ratio and the like of the edge of the grating in the preparation process can be avoided, and the preparation process duration and the preparation input cost can be reduced based on an automatic process; the preparation precision of the three-dimensional grating is guaranteed, and meanwhile, rapid preparation and forming of t
