Embodiment 2

[0064] Using the equipment of embodiment 1, the printing method of composite additive is:

[0065] S1. The printed file is transmitted to the control system, and the control system completes the slicing design of the metal layer and the non-metal layer. The number of slices of the two materials is the same, and the thickness of the single layer is 0.01mm-1mm;

[0066] S2. The control system controls the lifting device to move the printing platform above the light-curing material tank, and the surface of the printing platform is not submerged by the light-curing material;

[0067] S3. The control system controls the multi-axis moving device to make the liquid metal inkjet device move according to the slicing design of the metal layer, and the control system controls the liquid metal inkjet device to spray metal droplets on the printing platform to form a metal layer structure;

[0068] S4. The control system controls the lifting device to move the printing platform down by one layer, so...

Embodiment 3

[0073] The equipment used in this embodiment is basically the same as that in Embodiment 1. For the sake of brevity of description, in the description of this embodiment, the same technical features as in Embodiment 1 will not be described, and only the differences between this embodiment and Embodiment 1 will be explained. Office:

[0074] Such as figure 2 As shown, the liquid metal inkjet device 1 used in this embodiment is a striker-type liquid metal inkjet valve, which includes a heating cavity, an insulated push rod, a micro nozzle, a feedback control system, an ink recovery system and other components. The transmitter 2 is a focused ultraviolet laser transmitter (using a laser diode in the ultraviolet band and a lens). This embodiment is the printing of a special-shaped structure circuit, that is, the size and structure of the printed structure layer and the layer are inconsistent.

Abstract

The invention provides manufacturing equipment of metal and nonmetal composite additive. The manufacturing equipment comprises a liquid-state metal inkjet device, a light emitter, a multi-shaft moving device, a printing platform, a lifting device, a photocuring material groove, a frame and a control system; a positive projection of the printing platform in the lifting direction is positioned in the photocuring material groove; and the liquid-state metal inkjet device and the light emitter are positioned above the printing platform. The invention further provides a manufacturing method of the metal and nonmetal composite additive. The method can effectively solve the problem of incapability of printing metal and nonmetal composite structures in traditional 3D printing, and can be used for quick customized processing of multi-layer, special-shaped or complex-structured electronic circuits. The printed composite structures are stable and high in precision; the method is easy to manufacture complicated via hole and blind hole structures in precise electronic circuits; and photocuring materials are adopted to achieve higher printing speed compared with plastic FDM.

Description

Technical field [0001] The invention belongs to the field of additive manufacturing, and in particular relates to a manufacturing device of metal and non-metal composite additive and its application. Background technique [0002] 3D printing is essentially a rapid additive manufacturing technology. The existing 3D printing materials mainly include two types of metal and non-metal (non-metal is mainly plastic). The 3D printing of these two types of materials has their own applications and their respective irreplaceability. . Existing metal 3D printing mainly uses aluminum alloy, magnesium aluminum alloy, titanium alloy and other materials. These materials generally have high melting points. If they are printed together with plastic materials, the plastic materials will melt directly, making it difficult to perform composite printing with plastic materials. Liquid metal is a general term for a type of low melting point metal or metal alloy and its derivatives. It has the character...
