Abstract

The invention provides an inert gas circulation and purification device for a three-dimensional metal printer. The inert gas circulation and purification device comprises a gas filter, a heat exchanger, a gas circulation pump and a vacuum molding bin. The vacuum molding bin is connected with the gas filter through a waste gas outlet pipeline. The gas filter is further connected with the heat exchanger. The heat exchanger is connected with a gas inlet of the gas circulation pump through a gas delivery pipeline. A gas outlet of the gas circulation pump is connected with the vacuum molding bin. By means of the circulation and purification device, the vacuum molding bin of the three-dimensional metal printer can be protected to work safely and stably, inert gas in the vacuum molding bin can be used effectively and circularly, cost is saved, and the structure is simple.

Description

technical field [0001] The invention belongs to the technical field of metal three-dimensional printing equipment, and in particular relates to an inert gas circulation purification device for metal three-dimensional printing equipment. Background technique [0002] A three-dimensional printer, also called a three-dimensional printer (3DPrinter, 3DP for short), is a process of rapid prototyping, which uses layer-by-layer accumulation to produce a three-dimensional model layer by layer, and its operation process is similar to that of a traditional printer. Metal 3D printers need to use inert gas to protect the molten metal. The current metal 3D printers use inert gas for one-time use and discharge it directly after use, which consumes a lot. Contents of the invention [0003] In order to solve the problem that the inert gas of the existing metal 3D printer cannot be recycled, the present invention proposes an inert gas circulation purification device for the metal 3D printi...
