The birth of multi photon 3D laser printing technology: printing millions of particles within 1 second

Multi photon 3D laser printing technology, as a disruptive micro manufacturing technology, is facing two major challenges: speed and material compatibility. However, the latest research has made breakthrough progress, successfully increasing printing speed tenfold while maintaining excellent detail accuracy.

In this remarkable study, scientists abandoned the traditional single beam printing method and instead adopted an innovative strategy of multiple focused beams working in parallel. This transformation greatly improves the production efficiency of voxels, making it possible to complete millions of micro fine component printing in just a few minutes.

From complex medical devices to micro customized drug delivery drones, these futuristic application scenarios are gradually becoming a reality.
To achieve this leap, researchers have carefully designed customized optical components to ensure optimal focusing and power transmission of multiple laser beams. The birth of this high-precision system not only significantly improves printing speed, but also expands the range of materials that can be processed, opening up broad prospects for various application fields.

This innovative research was published in the journal Light: Advanced Manufacturing and demonstrated its strong capabilities through two eye-catching demonstrations. Firstly, researchers have successfully printed millions of custom designed particles, laying a solid foundation for personalized healthcare and revolutionary drug delivery solutions. Secondly, they have created a massive and complex metamaterial containing over 1.7 trillion voxels, setting a new record in the field of microprinting.

It is worth mentioning that the popularization and widespread application of this technology also demonstrate enormous potential. Researchers have used commercial laser printers to manufacture key optical components, which further reduces costs and improves the affordability and accessibility of technology.

Looking ahead to the future, multi photon 3D laser printing technology will lead the field of micro manufacturing into a new stage of development. From complex micro machines to personalized medical implants, and then to breakthrough new materials, this technology will create a future world full of infinite possibilities for humanity. With the continuous breakthroughs in speed and accuracy limits, researchers are laying a solid foundation for future miniaturization printing technology.
