Color 3D printing device

Abstract

The invention belongs to the technical field of 3D printing equipment, and relates to a color 3D printing device. A main structure comprises a shell body, a sliding rail, a lifting sliding block, a conductive receiving plate, a high voltage static generator, a servo motor, a driving gear, a fixed shaft, a bearing, a color mixing rotary cage, a driven gear and an ejector pin assembly; the servo motor drives the driving gear to rotate, the driving gear is in engaged connection with the driven gear to drive the color mixing rotating cage to rotate, conversion of flexible ropes dipping different colors of raw materials can be achieved, micro motors drive driving rollers to rotate, the driving rollers drive driven rollers to rotate through connection of the flexible ropes, through downward extending of an ejector pin, protrusions are formed on the flexible ropes, melt / solutions on the protrusions are motivated to form jet flows through concentration of the induction charge formed in the high-voltage static field, the jet flow falls, and is cooled or cured or a solvent is volatized, cured and bonded together, and a solid in a certain shape is formed; and the ejector pin is lifted upwards, the protrusions disappear, the jet flow disappears, and 3D printing is achieved.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of 3D printing equipment, and in particular relates to a color 3D printing device, which can realize refined and fast printing of color products. [0003] Background technique: [0004] 3D printing is a rapid prototyping technology, also known as additive manufacturing technology, which uses polymer materials, metals, ceramics and other bondable materials to construct parts by layer-by-layer printing based on three-dimensional digital modeling. Technology has been widely used in construction, medicine, machinery manufacturing and aerospace and other fields. At present, 3D printing technology mainly includes two processes: fused deposition modeling (FDM) and stereolithography (SLA). The stacking and forming of the printed model has the advantages of various materials, high strength and low cost, but the product accuracy is far from meeting the processing requirements of complex structure products; the...

Problems solved by technology

[0005] The current 3D printing technology is limited to a single material, and can only print three-dimensional objects of one color, and cannot present multiple colors on one object at the same time

Printing multi-color products means that the materials of the printer need to be replaced, and the printer must stop working to replace the materials, which brings about the problem of connection accuracy and low efficiency, which cannot meet the needs of 3D printing of high-precision color products
