Laser construction structural color 3D printing method, device and equipment and storage medium

Abstract

The invention relates to the technical field of metal 3D printing, and discloses a laser construction structural color 3D printing method, device and equipment and a storage medium, the laser construction structural color 3D printing method is applied to the metal 3D printing equipment, and the metal 3D printing equipment comprises a printing laser used for sintering metal powder and a femtosecond laser used for machining a grating structure; the laser structural color 3D printing method comprises the steps that a printing model is subjected to layering treatment, so that the printing model is divided into a plurality of printing layers according to the preset layer thickness; responding to the printing signal to control a printing laser to print a plurality of printing layers in sequence layer by layer; selecting a currently printed printing layer as a target printing layer; and in response to completion of printing of the target printing layer, the femtosecond laser is controlled to carry out femtosecond laser on the target printing layer so as to form a preset grating structure on the surface of the target printing layer, so that the printed piece can display the required color, and pollution to the environment can be reduced.
