Colored three-dimensional (3D) printing equipment adopting ink-jet dyeing fused deposition molding method

Abstract

The invention discloses colored three-dimensional (3D) printing equipment adopting an ink-jet dyeing fused deposition molding method. The colored 3D printing equipment comprises a white thread printing raw material feeding mechanism consisting of an emptying wire tray 1, a stepping motor feeder 2 and a feeding guide pipe 3, a color ink supply module 4, a mixing heater 5, a static / dynamic pipeline mixer 6, a replaceable printing nozzle 7, a three-dimensional motion molding platform 8 with a heating function, and an equipment control system. The 3D printing equipment is characterized in that a three-primary-color principle is adopted, three colors, namely red, green and blue, are mixed according to a proper ratio so as to obtain almost all colors in natural world, ink in three colors of the red, green and blue is mixed according to different ratios to form different colored ink, and then a white thermoplastic material is heated and fused and is mixed with the colored ink for dyeing to serve as a colored printing raw material; a 3D printed colored product is obtained by using a fused deposition molding (FDM) method. The 3D printing equipment has the beneficial effects that a colored 3D printing equipment technology is provided, the defect that only single color or double colors can be printed by a FDM-method 3D printer at present is overcome, and the 3D printing application is enriched due to multi-color printing.

Description

technical field [0001] The invention belongs to the field of 3D printing, and relates to a principle of using the principle of three primary colors, that is, the principle that almost all colors in nature can be obtained by mixing the three colors of red, green and blue in an appropriate proportion. After different proportions are mixed to form inks of different colors, the white thermoplastic material is heated and melted and mixed with colored inks to be dyed as color printing raw materials, and color products are printed in 3D using the fusion deposition molding method (FDM method). [0002] Background technique [0003] 3D printing production technology is a kind of rapid near-net shape additive manufacturing technology. Its principle is that the software decomposes the three-dimensional parts and components designed by the computer into several layers of plane slices, and prints them out through 3D printers to produce the required materials of different materials.
