Researchers at the Karlsruhe Institute of Technology, using the method of highest accuracy injection-molded, can now produce a large series of smallest parts e.g. medical products, components in watches, small engines and more.

The LIGA process can be used to produce micro structures from ceramics, various metals, or plastics.
