Roll-to-roll, high-resolution 3D printing of shape-specific particles
Particles on the scale of hundreds of micrometres to nanometres are ubiquitous key components in many advanced applications including biomedical devices1,2, drug-delivery systems3,4,5,15, microelectronics12 and energy storage systems16,17, and exhibit inherent material applicability in microfluidics6,7, granular systems8,9 and abrasives14. Approaches to particle fabrication inherently have trade-offs among speed, scalability, geometric control, uniformity and material properties. … Read more
