Problems solved by technology

3DP technology can realize color printing and can use a variety of raw materials, but the products produced by it generally have rough surfaces and relatively poor precision
The printing accuracy of SLS printers is poor, and protective gas is required when printing certain materials, and it generally needs a certain period of cooling after printing is completed
[0008] For 3D printers, it is not easy to print color 3D products due to the specific process

Embodiment 1

[0088] The color 3D printer involved in this embodiment is as figure 1 As shown, one nozzle, one LED ultraviolet light source and one mobile support frame are installed on the X-Y working platform, one nozzle is connected to the pre-mixer, and the connected pre-mixer is equipped with three colors of red, yellow and blue. The three UV resin supply units of the UV resin material are connected, the support table and a fixed support frame are installed on the base, and a printing thickness calibration unit is used for thickness calibration. The temperature of the UV resin storage tank was controlled at 30°C. The LED ultraviolet light source is equipped with a quartz surface concentrating sheet. The area where the light is concentrated on the printing layer is 3cm×4cm. The angle formed between the LED ultraviolet light source and the nozzle is 30°, and the concentrating position is 8cm away from the spraying position of the nozzle.

Abstract

The invention discloses a color 3D (Three-dimensional) printer which comprises an X-Y working platform, a spray head, an LED (Light-emitting Diode) ultraviolet (UV) light source, a movable support frame, a support table, a base and a fixed support frame, wherein the spray head, the LED UV light source and the movable support frame are mounted on the X-Y working platform; the support table and the fixed support frame are mounted on the base; at least one spray head is connected with a premixer; and the connected premixer is at least connected with three UV resin feed units. With the adoption of the color 3D printer, one-way multilayer color printing, and area color printing can be achieved, and the printing efficiency is multiplied compared with the traditional 3D printer.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a color 3D printer and a method for preparing a three-dimensional product. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital files, using powder or curable materials, and manufacturing products by layer-by-layer printing. It is in sharp contrast to the subtractive manufacturing technology used in traditional manufacturing. In contrast, 3D printing is an additive manufacturing technology that forms the final product by superimposing layers of materials. [0003] The more mainstream 3D printing technologies include: fused deposition modeling (Fused deposition modeling, FDM), stereolithography (Stereolithography, SLA), selective laser sintering (Selective lasers intering, SLS), three-dimensional printing technology (3Dprinting, 3DP), etc. . [0004] SLA printer is one of the earliest commercial printers. ...
