Problems solved by technology

[0006] To sum up, the existing 3D printers have defects in the feeding and discharging of the nozzles. The X-axis, Y-axis, and Z-axis drive printing directions are too single, and the printing speed is relatively slow.

Embodiment Construction

[0026] Such as figure 1 As shown, the 3D printer disclosed in the present invention includes a multi-nozzle assembly 1, a double-arm type nozzle driving device 2, a lifting plate 3, a frame 4, an injection molding liquid mixing device 5, an injection molding robot arm device 6, and a printing base 7 . The multi-nozzle assembly 1 is composed of four individual print nozzles, and the inner diameters of the nozzles of each print head are different. The four print heads are divided into two rows and fixed on the mounting plate 14 of the multi-nozzle assembly 1 in two rows, as shown in FIG. figure 2 The mounting plate of the multi-spray head assembly 1 shown is connected to the double-arm type print head driving device 2, and the joints at the connection can realize the rotation of three rotational degrees of freedom, and the rotation is controlled by a stepping motor. The double mechanical arm spray head driving device 2 is installed under the lifting plate 3, and the joint can ...

Abstract

The invention discloses a novel three-dimensional printer which combines a quick forming principle with conventional shooting technique. The printer can be used for printing the spherical shell of an object first and then injecting material into the shell. The specific technical process comprises the following steps: a track is adopted for a nozzle mechanism to convey printing material, and a screw rod is used for pressurizing to extrude melted material. The nozzle is formed by four nozzles with different inner diameters so as to print different composite materials. Double manipulators are used for controlling a nozzle group to move along a printing track. An injection molding device is adopted for carrying out high pressure mixing and vacuum blending on injection molding materials. An injection molding manipulator is adopted to extract injection molding solution from the injection molding device, and then the injection molding solution is injected into the printed shell of the printer so as to obtain the complete entity of a printed piece and achieve efficient forming of the printed piece.

Description

technical field [0001] The invention relates to a rapid prototyping device, in particular to a three-dimensional printer. Background technique [0002] 3D printing technology utilizes the establishment of digital file models on the computer, uses molding materials, and constructs three-dimensional entities through layer-by-layer printing. [0003] In the 3D printer of the fused deposition modeling process, the molding material is generally a filamentous solid material that can be melted after being heated to a certain temperature. , is sprayed onto the substrate in the form of fluid, and the thickness of the sprayed layer of the printing material is uniform by controlling the feed rate. The traditional wire feeding mechanism only presses the filamentous material into the heating chamber through the pulley, which is easy to cause clogging and other disadvantages. [0004] In addition, at this stage, the nozzle movement of the 3D printer uses the X-axis, Y-axis, and Z-axis t...
