A kind of color 3D printer and the method for preparing three-dimensional product thereof

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. ...
