Glass-melting extrusion 3D (three-dimensional) printing device

Abstract

The invention discloses a glass-melting extrusion 3D (three-dimensional) printing device, comprising a feeding mechanism, a printing nozzle component and a printing platform, and further comprising a forming room, a mobile thermal insulation plate, a translational mechanism and a lifting mechanism, wherein the printing nozzle component comprises a guiding pipe, a nozzle and a heating module; the guiding pipe is butt-jointed with the feeding mechanism; the nozzle is connected with the guiding pipe; the internal temperature of the forming room is controllable, and an opening port is formed in the top face of the forming room; the mobile thermal insulation plate is used for sealing the opening port, and the nozzle penetrates through the mobile thermal insulation plate and extends into the forming room; the translational mechanism is provided with the feeding mechanism, the printing nozzle component and the mobile thermal insulation plate; a lifting end of the lifting mechanism extends into the forming room through the bottom part of the forming room, and the printing platform is arranged on the lifting mechanism. The printing device disclosed by the invention has the advantages that a separate forming room is taken as a forming space, so that the situation that the service lives of electronic devices and moving components are not shortened due to high temperature influence in the forming room can be guaranteed; meanwhile the mobile thermal insulation plate is arranged for sealing the forming room, so that the heat of the forming room is further insulated and the flexible movement of the printing nozzle component is guaranteed at the same time.

Description

technical field [0001] The invention relates to 3D printing technology, in particular to a glass melting extrusion 3D printing device. Background technique [0002] 3D printing technology, that is, additive manufacturing technology, is to produce a three-dimensional model layer by layer in a layer-by-layer manner. Under the command of computer programs and other auxiliary facilities, it can automatically and quickly materialize the design structure into a model with a certain structure and structure. Functional prototype objects can quickly evaluate and modify product design and structure, so as to shorten the product development cycle and reduce production costs. 3D printing is both an innovation and a continuation of the traditional manufacturing industry. Due to its small footprint, energy saving and environmental protection, it not only has a lot of room for development in the manufacturing industry, but is also used in many industries such as education, architecture, an...

Problems solved by technology

[0005] However, there are still problems with this printing method. The melting and outflow of the molten pool is limited by the size of the molten pool. The molten pool method has high requirements for the insulation of the box and the pipeline, so the cost also increases accordingly; and most of the printed samples are opaque. and poor dimensional accuracy; there is also the problem that the high-temperature printing environment of glass has a greater impact on the electronic devices and moving parts of the 3D printer, resulting in a reduction in the service life of the equipment
