Over the past year, we have seen a number of major milestones in the field of microscale 3D printing. Now there has been yet another, as researchers at Stanford University in California have developed a new microscale 3D printing process for the production of particles in a variety of shapes. What is most notable about the new process is its exceptional speed, allowing for up to one million highly detailed and customizable particles to be produced efficiently every day.
According to a press release from Stanford, these 3D-printed microscopic particles are suitable for use in manufacturing, medicine and research. For example, they could be used specifically in microelectronics, microfluidics and as abrasives for complex manufacturing processes as well as for drug and vaccine delivery. The research was funded in part by the Bill & Melinda Gates Foundation and the National Science Foundation Graduate Research Fellowship Program.

Until now, the production of such microscale particles has been exceptionally difficult. A very specific combination of light supply, resin properties and stage movement is required to produce the particles in a scalable manner. However, this new photopolymerization process provides a solution.
