Over the last decades inkjet printing has substantially improved, for example by adapting microfabrication technology in the production of the most recent inkjet printheads. However, the further enhancement of the inkjet printhead architecture is becoming physically limited and therefore increasingly expensive. The goal of making inkjet printheads higher resolved and use them as additive manufacturing tools in printed electronics and related fields has therefore been restricted. To make inkjet printing compatible with high-resolution 3D printing not incremental innovation in needed but actual distruption, a complete change of paradigm. Electrohydrodynamic printing, the basis of Scrona's NanoDrip printing, creates the force required to eject droplets directly inside the ink, at the nozzle exit where the force is actually needed. All problems related to creating a force inside the printhead itself and transmitting it to the nozzle exit inside a viscous medium are thereby eliminated. This leads to nothing less than the potential of increasing both the printing resolution and ink viscosity more than a hundredfold.

Patrick Galliker is CEO and co-founder of the ETH spin-off company Scrona. Patrick studied Nanosciences at University of Basel and subsequently got his PhD at the laboratory of Prof. Dimos Poulikakos at ETH Zürich. In parallel to his PhD studies Patrick enrolled for a Master in Advanced Studies in Management, Technology and Economics at ETH Zürich as well. For his company Scrona Patrick has already raised more than 10 Million Swiss Francs in funding and multiple recognitions, including a Guinness World Record for the smaller inkjet printed color image.
