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

Embodiment 1

[0045] Such as Figure 1~3 As shown, the glass melting extrusion 3D printing device of this embodiment includes: a programmable heating and cooling molding chamber 130; a feeding mechanism 120, which sends the glass material to the printing nozzle assembly 110 and provides molten glass extrusion force; the printing nozzle assembly 110 , the glass printing material is melted and extruded in the printing nozzle assembly 110; the printing platform 140 located in the molding chamber 130; the XY axis positioning system 150 (translation), 151 and the Z axis positioning system 152 (lifting ), and is thermally isolated from the molding chamber 130 by the movable heat insulating board 160; The combination.

[0046] The print nozzle assembly 110 includes a high temperature resistant cooling module 111 arranged outside the molding chamber 130 and a nozzle 112 with a heating system arranged inside the molding chamber 130. The high temperature resistant cooling module 111 passes through t...

Embodiment 2

[0062] Such as Figure 6 As shown, in this embodiment, except for the feeding mechanism, the rest of the structure is the same as that of Embodiment 1. The feeding mechanism 120 adopts a screw-type feeding device, and the glass powder 190 enters through the barrel 191 and the feed channel 192 through the extrusion of the compressed air 195. Screw 194. The rotation speed of the screw 194 is controlled by the motor 193 , so as to adjust the rate at which the glass powder 190 enters the print nozzle assembly 110 , thereby improving the accuracy of the printed product.

[0063] When printing, the glass material passes through the feeding mechanism 120 and enters the nozzle 112 along the feeding direction 200, where it melts into a molten state and is extruded from the nozzle 112 under the drive of the positioning system and deposited on the printing platform 140 layer by layer. The forming chamber 130 Maintain a temperature of at least 650°C inside to ensure the interlayer bondin...

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...
