Abstract
Additive-based electroforming manufacturing methods for producing turbomachine components and other metallic articles are provided, as are metallic articles manufactured utilizing such manufacturing methods. In various embodiments, the method includes providing a sacrificial tooling structure having a component-defining surface region. A metallic body layer or shell is deposited over the component-defining surface region utilizing an electroforming process. The tooling structure is removed, while the metallic body layer is left substantially intact. After tooling structure removal, the metallic body layer is further processed to complete fabrication of the metallic component.
