Abstract

The invention provides a low-melting-point metal freezing printing system and method. The system includes: a three-dimensional mobile platform, a freezing probe, a printing substrate, a liquid metal pool, and a plurality of leakage holes arranged on the edge of the liquid metal pool; The platform is used to fix the cryoprobe so that the cryoprobe can move along the X, Y and Z directions; the liquid metal pool is used to hold the liquid metal material for metal printing; the printing base is set in the center of the liquid metal pool , used to carry the printed metal device or pattern in 2D printing mode; the freezing probe is used to freeze the liquid metal material located on the printing substrate in the liquid metal pool by using high-pressure nitrogen to make it shape; the material leakage is small The holes are used to recycle excess liquid metal material in the liquid metal pool. The metal printing system proposed by the present invention can switch between 2D and 3D printing modes, has a simple manufacturing process, can work continuously, shortens the production cycle, and reduces process costs.

Description

technical field [0001] The invention relates to the technical field of metal printing, in particular to a low-melting-point metal freezing printing system and method. Background technique [0002] Metal 2D printing mainly involves the field of printed circuit board (English name: Printed Circuit Board, English abbreviation: PCB), which is a structural component formed by insulating materials supplemented by conductor wiring. The application of PCB board covers almost all fields that use electronic equipment, such as computers, automobiles, medical treatment, aerospace and so on. [0003] At present, the production method of PCB board generally includes processes such as cutting, drilling, electroless copper plating, full board plating, outer layer circuit, pattern plating, outer layer etching, solder mask, forming, etc., so that this method has a process in the manufacturing technology. Complicated and long production cycle defects. [0004] 3D metal printing is a kind of ...
