Embodiment 1

[0052] In order to enrich the surface effects of SLA-based 3D printing products, an embodiment of the present invention provides a method for implementing SLA-based 3D printing. The specific processing flow of the method is as follows: figure 1 As shown, the following processing steps are included:

[0053] Step S110, making a planar or three-dimensional base material.

[0054] In-mold decoration technology has been widely used in the field of injection molding. In-mold decoration technology can be used to replace the traditional process of spraying paint, printing, electroplating and other processes after the parts are formed. In addition, it can also achieve realistic pattern decoration effects that cannot be achieved by traditional processes. The degree of exquisite appearance is beyond the reach of traditional surface decoration processes. within reach.

[0055] The film or leather with surface effect is used as the base material, and the base material can be a film used...

Embodiment 2

[0080] This embodiment provides a device for realizing 3D printing based on photocuring rapid prototyping, and its specific structure is as follows Figure 8 As shown, it includes: a sealing solution tank 81 , a planar substrate 82 , a curing light source 83 , a mold core 84 and a movement control mechanism 85 . Liquid photosensitive resin is housed in the sealing solution tank 81, the base material 82 and the curing light source 83 are arranged in the sealing solution tank 81, and the movement control mechanism 85 is connected with the mold core 84 to control the movement of the mold core 84 .

[0081] Specifically, the mold core 84 is used to be made of photosensitive resin or plastic or metal material, and is arranged in the sealing solution tank filled with liquid photosensitive resin. Hydraulically attach the planar substrate on the outer surface of the mold core; or, fill the sealing solution tank with gas, and generate air pressure from top to bottom on the substrate, ...

Abstract

The invention provides a stereo lithography apparatus (SLA)-based 3D printing implementation method and device. The method mainly comprises the following steps of arranging a base in a sealed solution tank with liquid photosensitive resin, and carrying out curing ray casting on the outer surface of the base so that the photosensitive resin at the inner surface of the base is cured by the curing rays and a 3D printed product is obtained, wherein the base is attached to the outer surface of the 3D printed product. Through arrangement of a base with a three-dimensional shape or a mold core attached with the base with a flat shape into the sealed solution tank, the SLA-based 3D printed product is attached with the base with surface effects so that the surface of the SLA-based 3D printed product has various effects such as leather qualitative sense and effects, fashionable element patterns and effects, and the like, and diversity of surface effects of the 3D printed molded parts is improved.

Description

technical field [0001] The present invention relates to the technical field of 3D printing, in particular to a method and device for realizing 3D printing based on SLA (stereo lithography apparatus, light curing rapid prototyping). Background technique [0002] With the emergence of 3D printing technology, many product shapes that were previously impossible can be manufactured by 3D printers. 3D printing technology is no longer limited to the male and female mold requirements of the traditional injection molding process, and can manufacture various products that cannot be molded by the injection molding process. For example, using 3D printing to form products with decorative substrates does not require setting the mold opening angle. The use of 3D printers to make parts with decorative pattern effects can not only reduce the constraints required by traditional injection molding processes and the problems caused by molding. And it also saves the time required to make molds....
