In biomedical engineering, additive manufacturing (AM), also referred to as 3D printing, has become a game-changing technique that makes it possible to create intricate, patient-specific implants and tissue scaffolds with previously unheard-of precision. This review summarizes recent developments in additive manufacturing (AM) technologies, such as fused deposition modeling (FDM), stereolithography (SLA), selective laser melting (SLM), electron beam melting (EBM), and binder jetting, and emphasizes their uses in tissue engineering, orthopedics, and dental prosthetics. The mechanical characteristics, biocompatibility, and osteoconductivity of novel materials, including polymers (PLA, PEEK, PLGA), metals (Ti, Co–Cr alloys), ceramics (hydroxyapatite, bioactive glasses), and composite systems, are examined. Furthermore, new developments like 4D printing, vascularized tissue bio-printing, and artificial intelligence integration for customized implants are analyzed. The significance of safe and efficient clinical translation is emphasized by addressing regulatory issues, ethical ramifications, and risk management systems. The assessment highlights present issues with scalability, standardization, and material performance while emphasizing AM's potential to transform patient-specific medical solutions.
