Embodiment 1

[0032] Such as figure 1 and figure 2 As shown, in this embodiment, the resin tank 114 is a circular structure, two oxygen tanks 5 are fixed on the side wall 104 of the resin tank 114, and the light-transmitting and oxygen-permeable film / layer 11 is only attached to the bottom of the resin tank 114, The driving device is located at the bottom of the light-transmitting and oxygen-permeable film / layer 11, and drives and connects the light-transmitting and oxygen-permeable film / layer 11 to rotate in the horizontal plane, thereby causing different parts of the light-transmitting and oxygen-permeable film / layer 11 to contact the oxygen tank 5, when When the oxygen concentration on the surface of the light-transmitting and oxygen-permeable film / layer 11 is low, oxygen diffuses from the oxygen tank 5 to the surface of the light-transmitting and oxygen-permeable film / layer 11, so that the blind area on the surface of the light-transmitting and oxygen-permeable film / layer 11 exists sta...

Embodiment 2

[0037] Such as image 3 As shown, in this embodiment, the resin tank 214 has a square structure; the driving device drives the connecting light-transmitting and oxygen-permeable film / layer 11 to reciprocate in the horizontal direction, and the rest of the technical features are the same as those in Embodiment 1.

[0038] In this embodiment, the driving mode of the driving device may be adhering friction driving or directly driving through a connecting rod.

Embodiment 3

[0040] Such as Figure 4 As shown, in this embodiment, the resin tank 314 has a circular structure, and the light-transmitting and oxygen-permeable film / layer 11 is fixedly connected to the side wall 304 of the resin tank 314 . An oxygen tank 5 is arranged inside the resin tank 314, and the oxygen tank 5 and the resin tank 314 are fixed separately, and the driving device drives the side wall 304 connected to the resin tank 314 to rotate in the horizontal plane, driving the light-transmitting and oxygen-permeable film / layer 11 in the horizontal plane Internal rotation causes different parts of the light-transmitting and oxygen-permeable film / layer 11 to be in contact with the oxygen tank 5. When the oxygen concentration on the surface of the light-transmitting and oxygen-permeable film / layer 11 is low, oxygen diffuses from the oxygen tank 5 to the light-transmitting and oxygen-permeable On the surface of the film / layer 11, the stable existence of blind areas on the surface of t...

Abstract

The invention discloses a light-curing-continuously-improving oxygen-permeation forming device, and belongs to the technical field of light-curing 3D printing devices. The device comprises a resin groove for containing photosensitive resin, a light-transmitting oxygen-permeation film / layer located at the bottom of the resin groove, a printing platform arranged on the resin groove and a projection device arranged below the resin groove, wherein oxygen grooves are formed inside the resin groove and are of hollow structures, the insides of the oxygen grooves are filled with oxygen, the upper ends and the side faces of the oxygen grooves are sealed, the bottom ends of the oxygen grooves are opened, and the oxygen grooves are in contact with the light-transmitting oxygen-permeation film / layer; the light-curing-continuously-improving oxygen-permeation forming device also comprises a driving device for driving the light-transmitting oxygen-permeation film / layer to move at the lower portions of the oxygen grooves. Compared with the prior art, continuous oxygen supplying to the surface of the light-transmitting oxygen-permeation film / layer is achieved, the problems that dead zone resin is cured, and a printed piece and the light-transmitting oxygen-permeation film / layer can not be continuously cured and formed are solved, and the light-curing-continuously-improving oxygen-permeation forming device has the advantages that the service life of the light-transmitting oxygen-permeation film / layer is prolonged, and the success rate of a CLIP light-curing printed piece is increased.

Description

technical field [0001] The invention relates to the technical field of light-curing 3D printing devices, in particular to a continuous lifting light-curing oxygen-permeable molding device. Background technique [0002] 3D printing is a kind of rapid prototyping technology. Rapid prototyping technology does not require special tools and molds. It has great flexibility, and the manufacturing process steps are simple. The manufacturing speed of products in single-piece production is fast, which can shorten product development time and reduce Development costs. [0003] Continuous liquid surface production (CLIP) technology is a recently developed rapid prototyping technology. Its principle is: there is an ultraviolet light projection device at the bottom, and the ultraviolet light gives way to the photosensitive resin in the raw material tank to cure, while oxygen inhibits the curing, and the raw material The bottom of the tank is provided with a light-transmitting and oxygen-...
