Additive manufacturing processes permit engine components to be produced by depositing multiple layers of a molten powdery base material. These new processes include selective laser melting and electron beam melting. The machine used for the purpose is controlled by means of CAD design data.
Additive manufacturing: fast, cost-effective and efficient
Compared with today's conventional production processes, additive manufacturing techniques offer far greater freedom of design and a high savings potential, since tools, such as casting molds, are no longer needed. They help markedly reduce the costs of blanks and substantially cut turnaround times. At MTU, such techniques are still in the development stage.
In the long term, plans are use additive manufacturing processes to produce integral components, such as casing segments with honeycomb liners that are presently made from brazed sheet metal segments, and bionically shaped components that cannot be manufactured using conventional methods.
