By means of the additive manufacturing platform equipment, exploration and product performance testing work of an additive manufacturing forming machining technology in the polar region environment can be achieved.

Description

technical field [0001] The invention relates to the field of metal additive manufacturing under a high temperature difference state, in particular to an additive manufacturing platform equipment under a cryogenic state simulating polar conditions. Background technique [0002] Additive manufacturing, also known as "3D printing technology", refers to the use of computer software to establish a three-dimensional model of parts, and process discrete materials (powder, liquid, wire, etc.) A low-loss stacking processing technology. Usually, in order to ensure the quality of molded products, the macro-environment of additive manufacturing is usually in a space above 25°C, and as far as possible in a closed or low-circulation wind area, laser coaxial powder feeding, arc fuse and other additive materials are used. manufacturing work.
