3D printing is an additive manufacturing technique used for the development of near net-shaped components. Its application in the manufacturing of Bio-implants has been growing due to the complexity of shape associated with these parts. Moreover, this technique has been successfully utilized for the manufacturing of customized implants as per an individual’s need, with improved mechanical properties imitating human bones. Furthermore, the advantages of 3D printed parts over conventionally manufactured parts include generating anatomic models for surgery simulation and control, as well as enhancing the bioactivity as a result of better process control in developing these bio-implants. The use of various 3D printing techniques for the development of different bio-implants utilizing varied materials (exhibiting desired properties) has been researched, recognized and successfully established in biomedical science. The present review article discusses and presents the state-of-the-art of 3D printing techniques associated with various bio-implants, limitations in the use of 3D printing techniques and remedial actions undertaken for overcoming these limitations. The article provides an in-depth analysis of existing problems in 3-D printed parts, both metal-based and polymer-based in an attempt to identify these causes and suggest techniques to bring about effective measures in this regard. The study has been concluded with a discussion on the growing demands of the development of bio-implants in the premises of hospital so as to minimize the chances of infection growth during transportation, and how 3-D printing is a promising method to fulfil such requirements.
