Medical Imaging Technology, 3D Printing and Medical Applications

Background: 3-dimensional (3D) printing denotes the various techniques, which are used to manufacture 3D anatomical from the patient data that is acquired. These models are rapidly gaining popularity in the medical community. Medical imaging modalities such as Computed Tomography (CT), Magnetic resonance imaging (MRI) and even ultrasonography have been used to assist in the manufacturing of 3D models. Currently, 3D printing has various medical applications, which includes pre-surgical planning, intra-operative planning, simulation models, manufacture of prosthesis and surgical tools. Methods: The PubMed database was searched for articles on 3D printing and applications of 3D printing. Relevant articles with basic physics, applications, advantages, and limitations were included in the study. The studies considered were dated from 2012 to 2022. Conclusion: 3D printing is rapidly gaining popularity in the medical field due to its numerous applications. 3D printed equipment has various advantages, such as better fit due to customized implants, better patient comfort along with lesser manufacturing cost. Simulation models, Preoperative and intra-operative models help in guiding the surgeons during the surgery as well as deciding appropriate approaches for a better surgical outcome and success.
