Prof. CHEN Shih-Chi and his team from MAE Department, collaborated with the Lawrence Livermore National Laboratory to develop the “Femtosecond Projection Two-photon Lithography (FP-TPL)” printing technology. By controlling the laser spectrum via temporal focusing, the laser 3D printing process is performed in a parallel layer-by-layer fashion instead of point-by-point writing. This new technique substantially increases the printing speed by 1,000 – 10,000 times, and reduces the cost by 98%. The achievement has recently been published in Science, affirming its technological breakthrough that leads nanoscale 3D printing into a new era.
