Let capillarity works its magic!

Our patented method revolutionizes micronic and sub-micronic printing by employing a direct approach. Derived from AFM (Atomic Force Microscope) technology, it swaps scanning probes for micro capillaries. These “micropens,” filled up with with liquid, are attached to a macro-resonator resembling a musical tuning fork. Oscillating at a controlled frequency akin to hummingbird wings, the micropens are positioned above the substrate on a nanopositioning stage. Drawing upon capillarity, the substrate’s contact triggers the extraction of a liquid droplet, forming a meniscus detected by a resonator frequency shift.

Our unique closed-loop electronics stabilize the meniscus, controlling table movement in controlling table movement in X, y direction and pipette movement in Z direction to craft your required pattern. Like an AFM, the oscillating tip adapts to substrate topography, using the micropen’s diameter tip for desired resolution. Deposition occurs through continuous capillary action, requiring no external energy. These precise resolutions are unparalleled at such scales – the remarkable power of capillary forces!

Our in-house developed AI tools play a pivotal role in augmenting our technology. By implementing intelligent trajectory plotting, advanced image recognition, and meticulous ink monitoring, we achieve unmatched efficiency and accuracy. Notably, our systems are meticulously calibrated to use just the desired amount of ink, ensuring optimal resource utilization. As we progress, our dedication to continuous innovation keeps us at the industry’s forefront, consistently introducing new features to meet evolving demands.
