Two-photon lithography technology

3D printing is a relatively slow miracle; so engineers at the Chinese University of Hong Kong and the Lawrence Livermore National Laboratory have devised a super charger called “Femtosecond Projection Two-photon Lithography.”  “By controlling the laser spectrum via temporal focusing, the laser 3-D 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 percent.”  The developers envision using this in manufacturing micro robots, drug delivery and medical devices, but, so far, not in bioprinting.  MORE
