Science Explained | Introduction to Spatiotemporal Focusing Technology
Two-photon polymerization (TPP) has become a key technology in the field of 3D nanofabrication, thanks to its high resolution—down to the sub-100-nanometer scale. However, traditional TPP printing systems typically rely on point-by-point serial scanning, which severely limits throughput and poses significant challenges for industrial adoption. In contrast, Femtosecond Projection Printing (FP)—a method based on spatiotemporal […]
