3D printing is a manufacturing technology that can physically design a model by fusing or decomposing materials such as resin, plastics, metal, carbon fiber, nitinol, paper, graphite, powder, and many different products. This method is also referred to as additive manufacturing (AM), rapid prototyping, or solid freeform fabrication. It can produce an object of any shape and size as visualize by a computer drawing file. It constructs the object layer by layer by injecting the material with the help of a printhead, a nozzle, or other various printing technologies. It first builds the basic object model along an x‐y plane and then subsequently starts building it along the z‐axis vertically. These instructions are being followed by a CAD file. 3D printers adopt the step‐by‐step instructions and deposit the material layer by layer, which results in a real‐time object model, and this model is being equipped with scaling, mudding, or painting if required.

Due to life‐changing innovations in 3D printing, most industries have started adopting its techniques because of its wonderful results. The healthcare industry has also been greatly affected by 3D printing because its emergence has overcome some challenges that not long ago seemed unsurmountable. Let us discuss some revolutionary changes that 3D printing has enabled in the healthcare sector. According to a survey, almost 6 percent of healthcare professionals have adopted this technology while the rest of them are in the process of adopting it. The most appealing 3D printing laboratory was found in New South Wales, and several skilled workers were hired to provide the services in the lab. They provide patients with such operational products that helps them to fulfill difficult tasks. The surgical tools and devices printed can help patients to improve their anatomy.

3D printing technologies that have been used in healthcare include orthotics prosthetics, implants, and preoperational models. 3D printing design models have specific customers whom they help to perform their activities in a better way. It can reduce patient visits to a hospital and can build such a difficult model that cannot be obtained by any other method. It uses materials such as polypropylene whose mechanical properties make the final product light in weight and easy to hold for patients.
