Coupling lithographic patterning with photopolymerization can create complex structures by sequential stacking of multiple layers. This process known as stereolithography (SLA) suffers from low scalability and a limit on the feature size of complex microstructures. A multi-focal point method has been approached to extend the fabrication area of two-photon polymerization SLA. This approach increases the fabrication area and reduces printing time but, the imaging optics still use a conventional one-to-one or one-to-array imaging system, thus the system still requires a serial scanning process. This limits the potential of scalable SLA due to the intrinsic lithographic scaling law of imaging systems. There is a need for scalable 3D printing systems that allow for large scale efficient printing without an undesirable loss of quality of the printed object.
