Polymer stamps are the heart of the GeSiM microcontact printers. The footprint of the stamp represents particular patterns for each customer and each application.

The proprietary stamping method doesn’t require sophisticated mechanical setups. When the print head touches down the stamp get’s bulged out by air pressure and connects smoothly and without artefacts to the substrate surface,
