Rapid shaping type full-color 3D (Three Dimensional) printer material conveying system and control method thereof

Abstract

The invention provides a rapid shaping type full-color 3D (Three Dimensional) printer material conveying system and a control method thereof and relates to the technical field of 3D printers. The system comprises a feeding system, a molten pool system, a spraying nozzle system and a heating system, wherein the feeding system is connected with an input end of the molten pool system; an output end of the molten pool system is connected with the spraying nozzle system; the heating system is connected with the molten pool system; the feeding system comprises a feeding pipe, a feeding motor, a motor controller and a material amount sensor; the heating system comprises molten pool heating equipment, a temperature sensor, a heating controller and spraying nozzle heating equipment. The method comprises the following steps: firstly, calculating amounts of wire rods with various colors, which are needed by a printing model; then controlling the feeding motor of the feeding system and accuratelycontrolling the amounts of the wire rods with the various colors; finally, gradually mixing molten materials through controlling the temperature of each molten pool of the molten pool system and conveying a mixture into a printing spraying nozzle. The system provided by the invention has the advantages of smooth printing, no blocking of the spraying nozzle, uniform full-color mixing and good full-color printing quality, has the characteristics of durability, simple structure, low cost and the like and is easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a rapid prototyping full-color 3D printer feeding system and a control method thereof. Background technique [0002] my country's 3D printing industry started relatively late, and is now entering a stage of rapid development. Therefore, 3D printing technology has a wide market, good prospects, and extensive applications. According to the tracking, research, analysis and summary of the latest developments in the field of 3D printing technology research and development in the world, and in line with the market, the current market has higher and higher requirements for 3D printing technology, from single-color to double-color, or even multi-color. [0003] 3D printing technology is a rapid prototyping technology field, it is based on digital model files, using metal, plastic [0004] materials, inorganic materials, etc., to construct objects by layer-by-layer printing. It is a...
