Advancements in polymer nanocomposite manufacturing: revolutionizing medical breakthroughs via additive manufacturing

3D printing technology has revolutionized product development in numerous industries. Due to 3D printing, innovative ways of directly giving drugs to patients, anatomical models for surgical planning and training, and tailored prosthetics and other medical equipment are all within the realm of possibility in the medical industry. 3D printing in healthcare has sparked a paradigm shift in creating medical implants and prosthetics. As a result of their exceptional mechanical, thermal, electrical, and optical qualities, polymers and composites made of them have gained widespread use in the medical industry. In this review article, we look at the most recent and cutting-edge benefits of 3D printing technology to create medical products out of polymers and composites. This article summarizes recent findings in patient-specific medical device and prosthesis design and manufacture and anatomical model development for surgical training and planning. Various 3D printing techniques, i.e., stereolithography, fused deposition modeling, and selective laser sintering methods, were examined, along with the pros and cons. Finally, we discuss the importance of 3D printing, which could significantly alter how medical devices are designed and produced, enhancing healthcare services and improving patient outcomes.
