Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0031] see figure 1 As shown, the present invention provides an optical-mechanical closed 3D printing device, comprising:

[0032] —The upper projection light machine module (1) includes a projection light machine based on a DMD chip, a Micro LED-based light machine, a projection light machine based on an LCOS chip, or an SLA projection light machine. The projection method is a top-down projection method. The components of the projection light machine module (1) do not include the lithography lens, and the upper projection light machine module (1) contains a Z-axis movement mechanism, which can adjust the work of the upper projection light machine module (1) to the light machine sealing film (3) Make sure that the image ...

Abstract

The invention discloses a light machine closed type 3D printing device. The light machine closed type 3D printing device comprises an upper projection light machine module, a housing, a light machinesealing film, a film clamping piece, a 3D printing platform, a printing platform lifting mechanism and a liquid tank, wherein the upper projection light machine module is fixed to any position of thehousing; the light machine sealing film is fixed to a protruding opening of the housing through the film clamping piece, and the surface of the light machine sealing film is flat through tightening; the liquid tank is positioned below the housing; the 3D printing platform is positioned in the liquid tank; the printing platform lifting mechanism is connected with the 3D printing platform; and the liquid tank is filled with photosensitive resin. A light machine closed type structure can prevent a lens from being polluted by dust, and meanwhile the light machine sealing film can be rapidly replaced and used at low cost under the situation that the light machine sealing film is polluted. The closed type housing is provided with a hole, and various kinds of gas are introduced in different workstates to achieve specific functions.

Description

technical field [0001] The invention relates to an optical-mechanical enclosed 3D printing device. Background technique [0002] 3D printing technology has also become "additive manufacturing". Due to its remarkable advantages such as the ability to realize the manufacture of complex structures, simplify the production process, and shorten the manufacturing cycle, it has a wide range of applications in the fields of medical treatment, scientific research, aerospace, and auto parts production. . SLA and 3D printing technology based on DMD chips are two commonly used 3D printing technologies. These two technologies can realize 3D printing of high-precision and complex structural parts in liquid photosensitive polymers, and the utilization rate of materials is high. The 3D printing technology based on LCOS chip and the 3D printing technology based on Micro LED technology are different from the traditional SLA and 3D printing technology based on DMD chip, which will achieve hig...
