Hummink - HPCaP (High Precision Capillary Printing) : A Technology for Next-Generation Manufacturing

High Precision Capillary Printing (HPCaP) technology redefines printing at the micron scale by leveraging capillary forces and resonance, eliminating the need for external energy sources such as UV, lasers, or pressure. Inspired by Atomic Force Microscopy (AFM), HPCaP employs a glass micropipette attached to a macro-resonator oscillating at controlled frequencies. This mechanism enables precise material deposition with resolutions from 50 μm down to 100 nanometers, adapting seamlessly to substrate topography in real time. Unlike conventional inkjet printing; HPCaP relies solely on capillarity, allowing the deposition of a wide range of materials as well as high viscosity materials, including polymers, conductive inks, and biomaterials. Its ability to print high-aspect-ratio structures and fine interconnects makes it ideal for semiconductor packaging, display repair, biosensors, and even watchmaking. With its sub-micron accuracy, adaptability, and compatibility with numerous inks, HPCaP stands as a versatile and sustainable solution for next-generation manufacturing challenges.
