Centimeter-scale superfine three-dimensional printing with femtosecond laser two-photon polymerization

11 Dec 2017 Chu Wei Tan Yuanxin Wang Peng Xu Jian Li Wenbo Qi Jia Cheng Ya

Nowadays three-dimensional (3D) printing has been widely used for producing geometrically complex 3D structures from a broad range of materials such as ceramics, metals, polymers, semiconductors, etc. Although it has been demonstrated that a fabrication resolution as high as ~100 nm can be achieved in 3D printing based on two photon polymerization (TPP), the end product size of TPP is typically on millimeter scale limited by the short working distance of high-numerical-aperture focal lens...
