The 2nd Nature article in the field of 3D printing technology in 2024 was published on March 13th. Building on a continuous liquid interface production technique developed at the university in 2015, researchers at Stanford University have developed a 3D printing technique for more efficient production of microscale particles, making up to 1 million micron-sized particles per day with high precision and customizability.

Nano- to micron-scale particles have a wide range of applications in biomedical devices, drug and vaccine delivery, microfluidics, and energy storage systems. However, conventional fabrication methods require balancing multiple factors such as fabrication speed and scalability with particle shape and uniformity and particle properties.
Researchers at Stanford University have developed a scalable, high-resolution r2r CLIP 3D printing process that uses single-digit micrometer resolution optics with continuous film to enable rapid, variable fabrication and harvesting of particles with a variety of materials and complex geometries. With this technology, researchers can achieve micron-level precision 3D printing while maintaining high production speeds and flexibility in material selection, opening up new possibilities for particle manufacturing.

This scalable particle production technology has been demonstrated toManufacturing potential in a wide range of fields from ceramics to hydrogel manifoldsThe research was published under the title "Roll-to-roll, high-resolution 3D printing of shape-specific particles," and subsequently has potential applications in microtooling, electronics and drug delivery. The study was published under the title "Roll-to-roll, high-resolution 3D printing of shape-specific particles".
