The first test artifact for two-photon polymerization 2PP using direct laser writing was made employing NanoFactory system

March 2, 2023

Exciting news for two-photon polymerization (2PP) and manufacturing: considerable advancement has been reported for next-generation quality assurance tools. Sven Fritzsche and colleagues from the Bundesanstalt für Materialforschung und -prüfung have introduced the first-ever test artifact for 2PP.

Similar to test artifacts already common in other additive manufacturing techniques, the proposed structural features can provide a general design guide for specific combinations of photoresist, laser power, and scanning speed. This unique manufacturing technology holds great promise for a burgeoning field!

The study was carried out with a Nanofactory workstation from FEMTIKA, equipped with a state-of-the-art C-Fiber 780 femtosecond fiber laser from Menlo Systems.

Femtosecond-laser direct writing 3D micro/nano-lithography using VIS-light oscillator

February 8, 2023

Team of Lithuanian scientists together with Mangirdas Malinauskas published an article on femtosecond laser two-photon polymerization 2PP lithography. The research was conducted using Laser Nanofactory by Femtika.

The experimental work is of high importance for fundamental understanding of laser enabled nanoscale 3D additive manufacturing and widens technology’s field of applications, such as micro-optics, nano-photonics, and biomedicine.
