Abstract (original English)

3D printing and bioprinting have become a key component in precision medicine. They have been used toward the fabrication of medical devices with patient-specific shapes, production of engineered tissues for in vivo regeneration, and preparation of in vitro tissue models used for screening therapeutics. In particular, vat polymerization-based 3D (bio)printing as a unique strategy enables more sophisticated architectures to be rapidly built. This progress report aims to emphasize the recent advances made in vat polymerization-based 3D printing and bioprinting, including new biomaterial ink formulations and novel vat polymerization system designs. While some of these approaches have not been utilized toward the combination with biomaterial inks, it is anticipated their rapid translation into biomedical applications.
