Abstract

The invention provides a metal three-dimensional printing vacuum molding cavity structure. The metal three-dimensional printing vacuum molding cavity structure comprises a working table, a sealing cabin, a cylinder body sealing part, a waste powder cylinder and an optical scanner; the sealing cabin is arranged on the working table and is in sealed connection with the working table; the cylinder body sealing part and the waste powder cylinder are both arranged below the working table and are both in sealed communication with the working table; the optical scanner is arranged on the top of the sealing cabin and is in sealed communication with the sealing cabin; an air inlet and an air outlet are formed in the two sides of the sealing cabin respectively; a raw material powder cylinder and a molding cylinder are arranged in the cylinder body sealing part; a first lifting device is arranged in the raw material powder cylinder, and a second lifting device is arranged in the molding cylinder; and the first lifting device and the second lifting device are both in sliding sealed connection with the cylinder body sealing part. The cylinder body sealing part, the waste powder cylinder, the optical scanner, the sealing cabin and the working table are in sealed connection, the area of the working table is vacuumized, and then is inflated with inert gas, and therefore it is ensured that a stable gas protection environment is provided in the whole printing process.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional printers, and in particular relates to a metal three-dimensional printing vacuum forming cavity structure. 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. SLM technology is based on Selective Laser Sintering (SLS) technology, based on the most basic idea of ​​rapid prototyping, that is, the "incremental" manufacturing method of layer-by-layer cladding, and directly forms parts with specific geometric shapes according to the 3D CAD model. The metal powder is completely melted during the forming process, resulting in a metallurgical bond. It is the latest development in rapid prototyping technology. The basic princi...
