Scientists at Purdue University have recently made a significant breakthrough in femtosecond laser 3D printing technology. They developed a novel two-photon polymerization technique that ingeniously combines two lasers for 3D printing. By doing so, they managed to print intricate, high-resolution 3D structures while reducing femtosecond laser power by 50%. This innovation not only promises to significantly reduce the cost of high-resolution 3D printing but also expands the potential applications of this technology across various fields.

Specifically, the research team combined a relatively low-cost visible light laser with an infrared pulsed femtosecond laser, greatly reducing the required femtosecond laser power. To optimize the balance between the two lasers, they developed a new mathematical model to better understand the photochemical processes and precisely calculate the synergistic effects of two-photon and single-photon excitation. Experimental results showed that for 2D structures, this method reduced the required femtosecond laser power by 80%, and for 3D structures, by about 50%.
Overall, this new technique not only reduces the cost of femtosecond laser 3D printing but also maintains its high-resolution capabilities. This groundbreaking development is expected to spur new applications in fields such as biomedicine, micro-robotics, and micro-optical devices. Moreover, since the new technique can be easily integrated into existing femtosecond laser 3D printing systems, it is likely to accelerate its adoption and expansion across industries.
