Researchers from multiple institutions have developed an optofluidic 3D microfabrication technique enabling the creation of microstructures from various materials, including metals and quantum dots. The method combines two-photon polymerization with light-driven fluid flow, overcoming material limitations in high-resolution 3D printing.

Successful assembly relies on the balance between particle interactions and fluid dynamics, achieving assembly rates of 10⁵ particles per minute. The technique supports a wide range of materials and has demonstrated practical applications in microfluidics and robotics.
