Scientists at KERI’s Intelligent 3D Printing Research have developed pioneering technology for printing high-resolution 3D microstructures using MXene , a two-dimensional material that has earned the nickname “dream material” for its exceptional conductive properties and potential in electromagnetic shielding and energy storage applications.
What is MXene?
It is a two-dimensional (2D) material that belongs to a class of compounds composed of alternating layers of metal and carbon or nitrogen. MXene, discovered in 2011 in the United States , is known for its high electrical conductivity, making it ideal for applications in advanced batteries and electromagnetic interference protection systems.
However, until now, this material has been virtually unattainable for 3D printing, due to the challenges inherent in ink viscosity and the need for additives that compromise its properties.
The key is in the meniscus method
The KERI team, led by Dr. Seol Seung-kwon, has overcome these challenges using an innovative technique called the meniscus method, which enables the formation of a perfectly controlled ink droplet under constant pressure.
This approach has allowed researchers to develop a MXene-based nanoink capable of creating structures with a resolution of up to 1.3 µm , or 270 times more precise than previous 3D printing technologies.
Our work not only addresses the technical challenges of printing with MXene, but also opens the door to a new era in high-precision 3D microcomponent manufacturing.
Dr. Seol Seung-kwon stated.
Impact on various industries
With micrometer resolution, this 3D printing technology promises to transform key sectors such as high-efficiency batteries, energy storage, and electromagnetic shielding. By enabling the creation of smaller, denser structures, the miniaturization of electronic devices could achieve new levels of efficiency, maximizing energy density and improving sensor sensitivity.
Electromagnetic shielding will also benefit from the amplification of internal reflections and the absorption effects of MXene nanoparticles .
KERI plans to explore strategic alliances for the commercialization of its technologies, positioning itself as a market leader in ultra-small and flexible electronic devices that are not limited by their physical form. Furthermore, this breakthrough opens up new possibilities in the field of nanotechnology and 2D materials, especially in applications requiring high-resolution, highly conductive structures.
