The invention provides a 3D printing forming casting method for a large-scale complex thin-wall high-temperature metal component. The method comprises the data acquisition process, the process designand forming and simulation optimization pouring process, the SLS wax model 3D printing process, the casting system evanescent mode foam forming process, the process gating system assembling and shellmaking process, the roasting and demolding process, the vacuum casting process, the pressurization solidification process, the metal component cleaning process, and grinding and polishing process. According to the casting method, the advantages of the 3D printing process, the investment casting process, the evanescent mode casting process are combined, so that a reliable technical scheme is provided for rapid preparation of the large-scale complex thin-wall high-temperature metal component; the problems that the air permeability is poor, the feeding distance is insufficient are solved by adopting the vacuum pressurizing pouring process; and the production period of the large-scale complex thin-wall high-temperature metal component is shortened from 1-3 months to less than 10 working days,and rapid production of the large-scale complex thin-wall high-temperature metal component is realized.
