3D printing method

Abstract

The invention belongs to the field of printing, and particularly relates to a 3D printing method. The 3D printing method comprises the following steps that a charcoal stick is prepared; the charcoal stick is positioned in a 3D printer to be processed to form a printing material; a dispersing agent is added to the printing material; the printing material is re-positioned into the 3D printer, and a3D model is unloaded from a website; the 3D printing material is loaded, a printing platform is debugged, printing parameters are set, and the 3D printer starts to work, wherein the 3D printer comprises a printing box, a smashing unit, a feed unit, a stirring unit and a conveying unit, and the printing box is a rectangular box body; the charcoal stick is smashed in the smashing unit, forms charcoal stick debris, and enters the printing box; a pasting agent is added in the printing box; carbon dioxide gas is introduced into the printing box through a gas inlet; the stirring unit fully stirs thepasting agent and the charcoal stick debris; and the pasting agent and the charcoal stick debris form the printing material after full mixing, and are conveyed out of the printing box under action ofthe conveying unit to print white paper.

Description

technical field [0001] The invention belongs to the field of printing, specifically a 3D printing method. Background technique [0002] 3D printing technology is to convert the three-dimensional model designed by CAD in the computer into multiple two-dimensional planes, use powdered metal or plastic and other bondable materials, and scan and fill layer by layer through filling equipment to form the final model parts. [0003] Ordinary 3D printing generally uses laser beams, hot-melt nozzles, etc. to accumulate and bond powdery, liquid or filamentary metals, ceramics, plastics, cell tissues and other materials layer by layer, and finally superimpose and shape them to produce physical products. However, among them, the method of using laser beams has cumbersome printing steps and high requirements on the printing environment, while the method of hot-melt nozzles consumes a lot of energy, and the safety of the printing process is low. A new 3D printing method is proposed It's ...

However, among them, the method of using laser beams has cumbersome printing steps and high requirements on the printing environment, while the method of hot-melt nozzles consumes a lot of energy, and the safety of the printing process is low. A new 3D printing method is proposed is a question people are thinking about
