Recently, with the deep integration of materials science, artificial intelligence, and additive manufacturing technology, the application of 3D printing in the medical field has ushered in an upgrade toward scale, refinement, and intelligence. From personalized implant prosthetics, regenerative organ printing, and precise surgical planning to medical education and training and novel drug delivery, 3D printing, leveraging its core advantages of customization, high efficiency, and high adaptability, continues to resolve the pain points of standardization and homogeneity in traditional medicine. It has formed a full-chain solution covering clinical diagnosis and treatment, rehabilitation care, medical research and development, and talent cultivation, becoming the core driving force behind the digital and precision transformation of the healthcare industry.

Under the traditional medical model, fields such as orthopedic repair, chest wall reconstruction, dental correction, and organ transplantation have long faced persistent challenges. Standardized medical devices struggle to adapt to the individual physiological differences of different patients, frequently leading to issues such as poor fit, suboptimal recovery outcomes, and frequent postoperative complications. Complex surgeries lack intuitive references for preoperative planning, and training for novice doctors is costly and high-risk. Organ transplantation suffers from donor shortages and difficult matching, causing countless patients to miss the optimal treatment window. 3D printing technology, relying on its capabilities in 3D scanning, intelligent modeling, and precision forming, perfectly aligns with the personalized diagnosis and treatment needs of the "one patient, one plan" approach in medicine, offering new pathways to address various medical pain points.

In the field of precision clinical diagnosis and treatment, customized 3D-printed implantable devices have achieved routine implementation, with continuous improvements in technological maturity and clinical safety. The 3D-printed polyether ether ketone (PEEK) chest and rib prosthesis developed by domestic research teams, as the world's first additively manufactured chest and rib reconstruction product, precisely matches the anatomical structure of the patient's defect site and perfectly adapts to the biomechanical characteristics of human movement, filling the technical gap in personalized chest wall defect repair in China. It has been awarded first prize for provincial scientific and technological progress, bringing safe and efficient treatment options to patients with chest and rib defects caused by tumors, trauma, and congenital malformations. In the dental field, integrated 3D printing digital solutions have been fully implemented, enabling rapid one-stop customization of dental models, aligners, and implant guides, significantly shortening dental treatment cycles and markedly improving oral medical precision and clinical efficiency. Meanwhile, high-precision 3D-printed bone and joint models help doctors accurately simulate surgical procedures before surgery, predict surgical risks, and optimize surgical paths, greatly enhancing the success rate of complex orthopedic and maxillofacial surgeries.

In the fields of regenerative medicine and innovative treatment, 3D bioprinting technology has achieved breakthrough progress, reshaping the treatment landscape for difficult diseases. Frontier results released at the 2025 Congress of the European Society for Organ Transplantation show that research teams used alginate and decellularized human pancreatic tissue to prepare customized bioink, successfully printing high-density, high-viability functional human islet tissue. The printed islets are structurally stable, capable of long-term glucose-responsive insulin release, and outperform traditionally prepared products in functional performance, opening a new avenue for cell therapy in diabetes and effectively alleviating the shortage of organ transplant donors. In addition, the application of novel deformable gel materials allows 3D-printed stem cell tissues to grow precisely in a flexible environment simulating the human uterine cavity, laying an important technical foundation for the development of artificial organs and organoids. Implantable sensors developed through near-infrared 3D printing in vivo manufacturing technology can achieve non-invasive in-body forming through external light exposure, accurately capturing human muscle movement signals and providing new technical support for rehabilitation monitoring and chronic disease diagnosis and treatment.

In the fields of medical education and device innovation, 3D printing technology has established a low-cost, high-fidelity medical training and R&D system. Currently, high-precision 3D-printed anatomical models are widely used in specialized surgical training. Eye anatomical models launched by European companies highly replicate the multi-layered tissue structures of the human eye, including skin, muscle, and fat, and can be precisely used for hands-on eyelid surgery training, thoroughly solving the problems of low fidelity, high wear rate, and poor practical effectiveness of traditional training models. At the same time, new medical devices such as 3D-printed microneedle patches are iteratively being implemented, enabling precise delivery of skin medications and vaccines without the need for syringes, overturning traditional drug administration methods and providing lightweight, painless new solutions for dermatology, chronic disease medication, and vaccination.

As the technology system continues to improve, multiple regions in China have established specialized 3D printing medical innovation platforms. Hospitals in cities such as Quzhou have launched AI + 3D printing medical concept verification centers, building a full-process technology system of "3D modeling - intelligent adaptation - precision manufacturing - clinical verification," focusing on core clinical needs in orthopedics and rehabilitation, driving medical services toward a comprehensive leap in precision, individualization, and standardization, and supporting the upgrading of regional medical service capabilities.

Industry experts indicate that current 3D printing medical applications are extending from single-device manufacturing to multiple dimensions including regenerative medicine, intelligent diagnosis and treatment, and innovative medical R&D. In the future, with the iteration of bioinks, upgrades in intelligent algorithms, and declining costs of large-scale production, 3D printing will achieve greater breakthroughs in areas such as mass production of artificial organs, precision treatment of difficult diseases, standardization of primary healthcare, and domestic production of high-end medical devices. At the same time, the industry will continue to improve technical standards, clinical certification, and regulatory systems, promoting the standardized and large-scale implementation of the technology.

There is no doubt that 3D printing technology is deeply reshaping the medical and health industry ecosystem, breaking down traditional medical technology barriers and resource bottlenecks, and injecting core momentum into the development of precision medicine, smart healthcare, and inclusive healthcare. In the future, it will continue to safeguard national health and usher in a new era of personalized medicine.
