Abstract:
One aspect is a method for the production of a three-dimensional structure of successive layers producing a multitude of successive layers wherein, with the exception of a first layer, each of the successive layers is arranged on a preceding layer. Each of the successive layers includes at least two materials wherein one material is a sacrificial material and one material is a structure material. Each of the successive layers defines a successive cross-section through the three-dimensional structure. Producing each of the layers includes depositing the sacrificial material by means of an electrochemical process and depositing the structure material by means of physical gas phase deposition. After a multitude of successive layers has been produced, the three-dimensional structure is uncovered by removing at least a part of the sacrificial material. The sacrificial material is at least one of a group consisting of nickel, silver, palladium, and gold.
