specific Embodiment approach 1

[0043] Specific implementation mode one: combine Figure 1 to Figure 4 Describe this embodiment. The aluminum alloy ultrasonic-assisted 3D printing device in this embodiment includes an industrial control cabinet 1, an ultrasonic-assisted printing module, a storage and delivery module, and a three-dimensional mobile module. The industrial control cabinet is the computer control system of the entire device, and the ultrasonic-assisted printing module, The metal storage tanks 31 of the material storage and conveying module are all fixed on the three-dimensional mobile module to realize three-dimensional printing.

[0044] The ultrasonic auxiliary printing module includes an ultrasonic transducer 21, a cooling water outlet 22, a cooling water inlet 23, a horn 24, an ultrasonic tool head 25, a nozzle 26, a substrate 43, a first temperature sensor 27, and a third temperature sensor 47 , an aluminum alloy part 51, a first heating module 61, a third heating module 63 and a heat insul...

specific Embodiment approach 2

[0047] Specific implementation mode two: combination image 3 with Figure 4 Describe this embodiment, the nozzle 26 on the ultrasonic tool head 25 of this embodiment, the diameter range of the liquid metal outflow pipe at the printing nozzle is 20 μm-1000 μm, the outflow pipe in the printing nozzle and the plane 262 transition with the first rounded corner 261 , the radius of the first rounded chamfer 261 is 50-600 μm. With the movement of the platform, the rounded chamfer 262 can make the transition of the extrusion process smoother. At the same time, due to the limited distance of ultrasonic action, the printing distance is generally 100-300 μm. Under such a narrow gap, the liquid metal tends to flow down the plane 262, and the squeezed liquid metal is in close contact with the plane 262. The plane 262 transmits ultrasonic waves into the liquid metal to produce a cavitation effect, and quickly breaks the aluminum surface at low temperature. The oxide film achieves micro-fu...

[0048] Specific implementation mode three: combination Figure 1 to Figure 4 Describe this embodiment. This embodiment provides an ultrasonic-assisted 3D printing method for aluminum-based composite materials. The method selects a temperature 20-100°C higher than the melting point of the metal material to be printed as the printing temperature, and the preheating temperature of the substrate It is 50-200°C lower than the melting point of metal materials, and the printing speed is 5-20cm / min.

Abstract

An aluminum alloy ultrasonic-assisted 3D printing device and a printing method thereof, which relate to a 3D printing device and a printing method. The present invention aims to solve the problem that the existing ultrasound-assisted liquid bimetallic direct 3D printing device and method not only cannot play the role of ultrasound in promoting the wetting and bonding of liquid metal, but also is not conducive to obtaining metal materials with consistent properties. In the present invention, pure aluminum or aluminum alloy metal in the form of powder or block is placed in the storage tank as a raw material, and after heating and melting, a certain air pressure is applied, and the gas extrusion force makes the liquid metal flow to the nozzle, and after flowing out of the nozzle, Under the action of ultrasound, the oxide film on the surface of liquid aluminum and the previous layer of aluminum or the aluminum substrate can be broken to achieve micro-fusion connection. Method: Select a temperature 20-100°C higher than the melting point of the metal material to be printed as the printing temperature, the preheating temperature of the substrate is 50-200°C lower than the melting point of the metal material, and the printing speed is 5-20cm / min. The invention is used for aluminum alloy printing.

Description

technical field [0001] The invention relates to an ultrasonic 3D printing device and method, in particular to an aluminum alloy ultrasonic-assisted 3D printing device and a printing method thereof, belonging to the technical field of 3D printing. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. In recent years, this technology has developed rapidly, and it is mainly divided into stereolithography technology, fused lamination technology, 3D inkjet printing technology, selective laser sintering technology and layered solid manufacturing technology. [0003] Although 3D printing technology is developing rapidly at present, the 3D printing of aluminum alloys is still subject to great restrictions. Aluminum alloys have properties such as easy oxidation, high reflection an...
