Problems solved by technology

[0003] 1. The beam needs to be imaged multiple times before it can be irradiated on the liquid photosensitive resin. The beam after multiple imaging will be optically deformed, resulting in an error between the shape of the formed solidified layer and the shape of the corresponding slice.
[0004] 2. Due to the need to distribute the optical path of the light beam, the shape is larger, which ultimately makes the shape of the light-curing 3D printer larger

Embodiment Construction

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as Figure 1-4 As shown, one embodiment of the present invention provides a light-curing 3D printer, including a tank 1 containing a liquid photosensitive resin 2, a carrier plate 3, a driving mechanism 5, a beam generating assembly, and a liquid crystal screen 4; the tank 1 It needs to be fixed, and it is better to keep it horizontal to prevent the liquid photosensitive resin 2 from flowing out; the carrier plate 3 is used to accept the cured photosensitive resin 7 (the cured photosensitive resin 7 is actually the printed part of the target printing part); the driving mechanism 5 is connected to the carrier plate 3 through a connecting rod 6, and the carrier plate 3 is driven to move through the connecting rod 6; the...

Abstract

The invention discloses a light-cured 3D printer. The light-cured 3D printer comprises a carrier plate, a driving mechanism, a containing tank, a light beam generation assembly for providing parallel light beams and a liquid crystal screen for forming a light transmittance zone with a slice shape. Parallel light beams produced through the light beam generation assembly perpendicularly go through the light transmittance zone and irradiate liquid photosensitive resin. The parallel light beams produced through the light beam generation assembly go through the light transmittance zone of the liquid crystal screen and irradiate the liquid photosensitive resin so that the resin is cured, and the parallel light beams going through the liquid crystal screen are not refracted and reflected and thus the shape of each layer of the cured photosensitive resin is the same to that of the corresponding slice and a printing precision is high. When the parallel light beams are formed, the theoretical shortest distance from a spot light source to the liquid photosensitive resin is one focal length of a lens or is equal to thickness of a light guide plate and thus the light-cured 3D printer has a small volume and is convenient for carrying and use.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a photocuring 3D printer. Background technique [0002] 3D printing technology, also known as additive manufacturing, refers to the process of layering and discretizing the three-dimensional model through a program, and then using powdered metal, resin or plastic and other bondable materials to construct entities by layer-by-layer accumulation. 3D printing technology is different from traditional subtractive machining technology, which is usually realized by cutting or drilling. 3D printing technology can manufacture complex objects and can better save production raw materials. In the past, it was often used to manufacture models in the fields of mold manufacturing and industrial design. Today, it is driven by the requirements of personalized and specific service manufacturing. , is gradually being used for direct manufacturing of some products, especially some high-value ap...
