Plasma sources for the modification of two- and three-dimensional surfaces and microplasma sources

At the Fraunhofer IST, new plasma sources are being developed for integration into existing process chains. In contrast to industrially available systems, the focus here is often on special geometries of the components (2D or 3D substrates, internal coating) or on location-selective treatments. The latter are often summarized under the term plasma printing. The integration of µ-plasma sources in additive-manufacturing processes or on robot-guided systems is, however, also a topic of research at the IST.

Adapted plasma sources for (almost) any dimension

The integration of customer-specific plasma sources into existing process chains enables cost-effective processes for the control of interfacial chemistry. Microplasmas allow plasmas to be realized in small cavities (down to a few 10 µm). Plasma sources in additive manufacturing serve the adhesion control of multi-material systems or for biological systems. Composite layers with high mechanical stability can also be realized through adapted plasma processes and sources, as can applications for cleaning and disinfection.
