Abstract
A method for manufacturing components having thin walls of complex design by depositing a layer of metal or ceramic material on a shaped substratum. The resulting coated shaped bodies are then arranged inside an external envelope such that the shaped bodes represent the cavities to be incorporated in the component under manufacture whereas the coatings represent the walls surrounding the cavities. The envelope is then hermetically sealed, evacuated and upon evacuation, subjected to a hot compression operation. Thereafter, the envelope and the shaped bodies are at least partially removed by chemical or mechanical processes. Several layers of various materials and various chemical and physical properties can be deposited on the shaped bodies to form the walls.
