The research team from Cornell University has developed a brand new 3D printing process over nearly a decade, which can significantly enhance the performance of compound superconductors.
This research is led by Professor Ulrich Wiesner from the Department of Materials Science and Engineering at Cornell University, primarily combining 3D printing and heat treatment to achieve a new method for manufacturing superconductors.
The core step of this process is 3D printing. The researchers first prepared a special “ink” composed of copolymers and inorganic nanoparticles, and printed it onto the substrate surface.
Subsequently, the samples underwent high-temperature treatment, transforming the ink into a porous crystalline superconductor, which forms a regular lattice at the atomic scale while maintaining the shape imparted by 3D printing at the macroscopic scale.
This multi-level structure refreshes the effective surface area record of compound superconductors, and a larger surface area means more active sites, which can significantly enhance the material’s performance in electronic transport and other aspects, thereby providing potential support for resource-intensive fields such as quantum computing.
Professor Wiesner stated that this achievement embodies nearly ten years of the team’s efforts.This method has currently only been successfully validated on crystalline nitrides, but theoretically, it can be extended to other metallic compounds, such as titanium nitride, which, despite differing properties, can still achieve similar high surface area characteristics.
The research is still in its early stages, and further validation and optimization are needed before industrial applications can be realized. However, this achievement provides a new perspective for the manufacturing of superconducting materials and demonstrates the enormous potential of 3D printing in the field of advanced materials, which may drive the development of cutting-edge technologies such as quantum hardware.
