A fast color three-dimensional printer

Abstract

The invention provides a rapid color three-dimensional printer including a base, a telescopic bracket, a rotating shaft, a worktable, a supporting seat, N telescopic rods, N print spray heads, N storage tanks, N connection pipes, N suction pumps, N + 2 driving mechanisms and a control module; the support the seat is arranged on the base, the N telescopic rods are movably, horizontally and parallelly arranged on the supporting seat and is located one side close to the worktable, the N print spray heads are respectively arranged on the N telescopic rods, distance between the N print spray heads and the worktable can be adjusted by stretching of the N telescopic rods, the N storage tanks at least comprises one a base material storage tank, and the rest of color material storage tanks, the base material storage tank is used for storing a base material, the color material storage tanks are used for storing color printing materials, the N print spray heads are respectively connected with the N storage tanks through the N connection pipes, and the N suction pumps are arranged on the N connection pipes. The rapid color three-dimensional printer is provided with a plurality of spray heads, is conducive to improving the printing speed, and can avoid surface chromatic aberration.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a fast color three-dimensional printer. Background technique [0002] 3D printing is a rapid prototyping technology based on digital model files, using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold making, industrial design, etc., and is now gradually being used in the direct manufacturing of some products, especially some high-value applications, such as hip joints or teeth, or some aircraft parts, etc. have been used Parts printed with this technology. The technique is also known as cumulative manufacturing, as the item is printed by building up the material layer by layer. [0003] Most of the existing 3D printers only have one print head. When printing workpieces that require multiple consumables, the consumable storage device connec...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing 3D printers only have one print head. When printing workpieces that require multiple consumables, the consumable storage device connected to the print head must be changed. This way of working not only prolongs the working time, but also easily causes multiple Mixing of consumables, affecting workpiece quality

For example, when using this type of printer to print a color model, the residual printing material in the print head and the input printing material are likely to form color difference and reduce the surface quality of the color model.
