2020 IEEE 33rd International Conference on Micro Electro Mechanical Systems (MEMS), 2020
In this talk, I will give an introduction into laser based 3D printing on the micro- and nanoscale, describe the state-of-the-art, and compare it to other 3D Additive Manufacturing approaches. I will emphasize two challenges, namely scalable/faster 3D printing and multi-material 3D printing, including “4D” architectures.

Rapid 3D nanoprinting utilizing spatiotemporal focusing
Laser 3D Manufacturing VIII, 2021Multiphoton polymerization has become a standard for 3D nanofabrication for its superior resolution and processing steps. However, it is often considered limited in its throughput capabilities, resulting in a desire for a more scalable process. An improvement to the speed of 3D nanoprinting via multiphoton polymerization can be achieved through a ...

3D Laser Nanoprinting: Recent Progress
Proceedings of the 2022 Conference on Lasers and Electro-Optics Pacific Rim, 2022Two-photon 3D printing has become a mature technology. Here, we review our efforts on using two-step absorption instead of two-photon absorption. The approach works with low-power continuous-wave laser diodes. We present one- and two-color results.
