Mixed color printing method of 3D printer

Abstract

The invention relates to a mixed color printing method of a 3D printer. The mixed color printing method comprises the steps that S1, the required preset amount of red, yellow and cyan consumable particles is calculated in advance according to the color of an object to be printed; S2, a preset amount of red, yellow and cyan consumable particles are conveyed into a conveying mechanism; S3, the conveying mechanism runs to pull the consumable particles of the three colors to enter injection molding pipes through feeding pipes; S4, a heating element runs to melt the consumable particles, and meanwhile a stirring mechanism is operated to stir the consumable particles, so that the three kinds of consumable particles are uniformly molten to be in a molten state; and S5, the injection molding mechanism runs again to provide injection molding pressure for the consumables in the molten state, and the consumables in the molten state are discharged outwards through an injection molding nozzle; meanwhile, a platform is moved according to a preset program, and matched with the injection molding nozzle, and therefore 3D printing of the object is completed; in the printing process, air generated by operation of a cooling fan is guided by a flow deflector to blow towards the platform in a vortex mode; and thus cooling air is provided for the printed object.

[0002] 3D printing is usually realized by using digital technology material printers. It is often used to manufacture models in mold manufacturing, industrial design and other fields, and is gradually used in the direct manufacturing of some products. There are already parts printed using this technology. , the technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields, however, existing Ordinary 3D printers basically cannot achieve multi-color printing of objects. Existing 3D printers generally choose consumables that match the color of the object to be printed as raw materials for 3D printing. This method requires the replacement of consumables according to the color of different printed objects. It is more troublesome. In addition, when encountering rare colors, the consumables need to be specially customized. Therefore, the present invention proposes a color-mixed printing method for 3D printers. , so as to form a molten consumable that matches the color of the object to be printed. It uses the principle that the three primary colors of the pigment can form all colors, and selects an appropriate number of red, yellow, and blue consumable particles in advance according to the color of the object to be printed. The molten state consumables that match the color of the object to be printed. In addition, the present invention can not only print an overall single-color object, but also an overall multi-color object. It only needs to calculate the amount of each color in advance.
