Abstract

The invention provides a low-melting metal freezing printing system and method. The system comprises a three-dimensional mobile platform, a cryoprobe, a printing base, a liquid metal tank and a plurality of small material leaking holes formed in the edge of the liquid metal tank. The three-dimensional mobile platform is used for fixing the cryoprobe to enable the cryoprobe to move in the X direction, the Y direction and the Z direction. The liquid metal tank is used for containing a liquid metal material for metal printing. The printing base is arranged at the center of the liquid metal tank and used for bearing metal devices or patterns formed by printing in a 2D printing mode. The cryoprobe is used for utilizing high-pressure nitrogen to freeze the liquid metal material positioned on the printing base in the liquid metal tank to enable the liquid metal material to be formed. The small material leaking holes are used for recycling the redundant liquid metal material in the liquid metal tank. According to the metal freezing printing system, the switching of the 2D printing mode and a 3D printing mode can be achieved, and a manufacturing process is simple. The low-melting metal freezing printing system can work continuously, the production cycle is shortened, and the process cost is reduced.

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.
