High-speed two-photon polymerization 3D printing with a microchip laser at its fundamental wavelength.

摘要: High-resolution, high-speed 3D printing by two-photon polymerization (2PP) with a Nd:YVO4 Q-switched microchip laser at its fundamental wavelength of 1064 nm is demonstrated. Polymerization scan speeds up to 20 mm/s and feature sizes 250 are achieved using high repetition rate semiconductor saturable absorber mirror (SESAM) photoresist new photo-initiator bearing 6-dialkylaminobenzufuran as electron donor indene-1,3-dione moiety acceptor. The obtained results demonstrate the potential lasers for applications in 2PP printing.
