Femtosecond projection two-photon printing technology for biomanufacturing

This talk present a femtosecond projection two-photon polymerization platform that suppresses localized thermal damage via a low-exothermic Type II photoinitiating system, enabling sub-micrometer-resolution hydrogel fabrication with 3–4 orders of magnitude higher throughput than point-scanning methods. Integrated with extrusion printing, this approach bridges micro-precision and macro-scale tissue engineering for multiscale biomedical applications.
