[0002] The existing printing platform is fixedly connected to the equipment, and a hole for installing the printing cylinder is set on the printing platform. The printing cylinder is fixedly connected to the printing platform, and the printing cylinder and the printing platform are fixed during the printing process. A powder spreading mechanism and a laser printing mechanism are connected to the printing substrate. The printing cylinder adopts an integral structure, and the printing substrate is connected in the printing cylinder. During printing, the printing substrate is lifted and lowered to control the printing space formed between the printing substrate and the top of the cylinder body, and the printing powder is spread on the substrate through the powder spreading mechanism.
