Two‐Photon Polymerization: Emerging Applications and Innovations in Clinical and Regenerative Medicine

Two‐photon polymerization (2PP) has enabled three‐dimensional printing at micro‐ and nanometer level resolution, allowing for the fabrication of patient‐specific implants and finely structured cell scaffolds. This comprehensive review highlights recent advancements in integrating 2PP across various medical specialties, emphasizing its potential role in clinical and translational settings including ophthalmology, orthopedics, neurology, dermatology, and otolaryngology. Despite technological achievements, significant challenges hinder its widespread use, which are also discussed. This includes scaling of manufacturing processes, ensuring long‐term biocompatibility of fabricated structures, and a lack of 2PP research in other medical fields. Advancements in biomaterials, photoinitiators, and integrated fabrication approaches within 2PP could significantly impact clinical practice and further improve patient outcomes.
