Problems solved by technology

[0006] The existing UDS technology also has the following disadvantages: For example, only a single non-metallic material or metal material can be sprayed: the product has a simple geometry and a single function, which cannot meet the requirements of wear resistance, high strength, and corrosion resistance for tiny parts in aerospace engineering.

Embodiment 1

[0021] Embodiment 1: with reference to accompanying drawing. Shape the heterogeneous miniature hollow cylinder, and its size is: the length of the hollow cylinder is 20mm, the outer diameter is Φ10mm, and the inner diameter is Φ4mm. Among them, the material in the hollow cylinder section Φ4-6mm is cast copper alloy ZCuAl8Mn13Fe3Ni2, and the hollow cylinder section Φ6-10mm material is composed of cast aluminum alloy ZL301 non-uniformly distributed. According to the material distribution of the hollow cylinder, use Pro-engineer to generate a three-dimensional model of the hollow cylinder; use the software SolidView to divide the cylinder into a series of two-dimensional hollow circles with a length of 0.05 mm along the Z axis to form two-dimensional slice data, and Preserve; Put the cast copper alloy of the forming material into the droplet generating device, put the cast aluminum alloy into another droplet generating device, and seal the vacuum chamber; supply the vacuum chambe...

Abstract

The invention discloses a micro-manufacturing method for rapid prototyping of heterogeneous functional devices, which adopts the following method steps: according to the requirements for manufacturing heterogeneous functional devices, different metals, alloy materials or non-metallic materials are respectively put into In different droplet generating devices, put low-melting point alloy materials or non-metallic materials as supporting materials into another droplet generating device, seal the vacuum chamber, adjust each control system, and complete the forming and deposition of heterogeneous functional devices. Once complete, the deposited parts are placed in a furnace to remove support material and yield heterogeneous functional devices. This method can form complex and small parts of various non-metallic materials or metal materials; the material can be selected according to the function of the device to meet the requirements of wear resistance, high strength and corrosion resistance of the device; it can also be used to manufacture polymers and Parts made of other materials have practical application value in biomedicine and civil use.

Description

technical field [0001] The invention relates to a rapid forming micro-manufacturing method for heterogeneous functional devices. Background technique [0002] Heterogeneous functional devices are composed of a variety of materials, and their microstructure changes unevenly. Some special functional devices can be formed according to the composition of materials, which has great application prospects in the aerospace field. Through the ingenious compounding of metals, ceramics, non-metals, etc., heterogeneous functional devices have great potential application prospects in the fields of nuclear energy, electronics, optics, electromagnetics, and biomedicine. Since the manufacturing method of heterogeneous functional devices is relatively complicated, different manufacturing methods can be selected according to the shape and function of the device, so people are exploring suitable manufacturing methods for heterogeneous functional devices to realize low-cost and high Efficiency...
