Titanium mesh plate incremental forming method and preparation method of cerebral skull prosthesis

The invention discloses a titanium mesh plate incremental forming method and a preparation method of a cerebral skull prosthesis. The method comprises the following steps: performing CT scanning to obtain skull image data of a patient, performing three-dimensional reconstruction to generate a skull model, obtaining a two-dimensional restoration by utilizing finite element analysis software, casting a titanium mesh with low-temperature alloy to manufacture a sandwich-shaped structural model, performing numerical simulation analysis on the model obtained after casting in a forming and rebounding process, modifying a processing track and designing a supporting model, and performing three-dimensional reconstruction on the skull model. And after the springback value meets the requirement, restoration machining forming is conducted in an incremental forming system, the low-temperature alloy material and a restoration base body are separated after forming, and the cerebral skull restoration and the like are obtained
