Laser additive manufacturing technology is growing more prevalent around the world for industrial uses, leading researchers to investigate further in relation to polymerization, with findings outlined in the recently published ‘ High-speed two-photon polymerization 3D printing with a microchip laser at its fundamental wavelength.’

 .

As sub-micrometer resolution offers ‘unmatched’ potential via laser technology today, the researchers state that spatial resolution down to 100 nm is possible with two-photon polymerization (2PP) technology.

 .

In this study, they discovered that using a Q-switched microchip laser improved both quality and performance remarkably: “Thanks to the laser performance and high 2PP reactivity of the prepared photoresist directly at the fundamental wavelength of our microchip laser, 2PP 3D printing speeds of up to 20 mm/s are demonstrated and objects with feature sizes down to 250 nm are produced,” states the research team. “These 2PP 3D printing characteristics are on par with femtosecond lasers.” The […]
