From-top-to-bottom liquid metal 3D printing forming equipment

Abstract

The invention discloses from-top-to-bottom liquid metal 3D printing forming equipment. The 3D printing forming equipment comprises a melting pot, a pulley block, a high-temperature-resistant bar, a high-temperature liquid level probe, a regulating valve, a liquid metal guide pipe, cooling gas nozzles, a sprayer, a forming platform and a manipulator. According to the equipment, a fixed sprayer andmoving forming platform strategy is adopted in the principle, the forming platform is operated through the manipulator, layer-by-layer stacking forming is carried out according to the hierarchical data of a product three-dimensional model, and a liquid metal material is synchronously solidified by the cooling gas nozzles. As for flow control, the flow of the liquid metal is controlled by utilizingthe size that the high-temperature-resistant bar extends into the melting pot and a homemade regulating valve, and a complicated metal component can be efficiently produced. The equipment has no limitation on metal smelting points, and the principle is simple and feasible. The equipment not only has the advantage of low cost but also can improve the mechanical properties of the metal product produced by printing.
