Title: Hyunjung Anna Kim: Advancing On-Demand Nanoscale 3D Printing.
Introduction
Hyunjung Anna Kim is an inventor based in Champaign, Illinois. Her work includes a patent for an on-demand, scalable nanoscale 3D printing system. Kim is associated with the U.S. Government as represented by the Secretary of the Army.
Latest Patents
Kim is named on 1 patent, titled “On-Demand Scalable Nano-Scale 3D Printing System.” The invention describes a system that uses a hydrodynamic flow-focusing nozzle to guide printing ink toward a substrate. A central channel carries the ink, while two side channels deliver sheath fluid that pinches and focuses the ink flow. A pulse generator applies an electric potential between the nozzle and substrate, enabling on-demand deposition and control of the ink’s ejection frequency. Separate syringe pumps adjust the ink and sheath-fluid flow rates.
Career Highlights
The patented system combines fluid-flow control and electrical pulsing to support precise, on-demand material deposition at the nanoscale. Its design provides adjustable control over both the printing ink and the sheath fluid.
Collaborations
Kim’s listed collaborators include Kyoo D. Jo and Sungmin Hong. The patent is associated with the U.S. Government as represented by the Secretary of the Army.
Conclusion
Hyunjung Anna Kim’s patent presents a controlled approach to nanoscale 3D printing, combining focused fluid delivery with electrical control to deposit printing ink on demand.
