Additive manufacturing of metallic biomaterials and its biocompatibility
Published in Elsevier Ltd
The techniques for making orthopaedic implants and devices have advanced significantly in recent years. The use of additive manufacturing technology enables the creation of intricate structures with biomimetic characteristics. Three-dimensional (3D) printed titanium orthopaedic implants were already used to repair severe pelvic bone abnormalities, and the production of thousands of non-individualized implants. The various adjustable variables in the 3D printing process and how they could interact with the potential variety of designs that might be produced must be understood in order to predict the efficacy and safety of AM made implants. A reasonably well-known technology known as powder bed 3D printing has revolutionised the process of creating personalised, multipurpose metallic implants for each patient's unique demands. Precise mechanical characteristics with porous implants, good pore topologies, and patient-oriented design functionalities can be created via AM. Although 3D printed Ti and its alloy Ti-6Al-4V have been studied and used in clinical applications from several years, further study is still needed to build porous AM titanium implants that would operate superbly over the long term. Although early clinical outcomes for 3D printed cups have been promising, additional extensive study is still needed, because regulatory approval systems have not fully kept up with technological innovation. For various applications, a variety of 3D printing methods, including selective laser melting, selective laser sintering, and electron beam melting, are discussed in this paper. The production of excellent porous metal implants has a lot of potential for additive manufacturing using powder bed fusion. © 2023 Elsevier Ltd. All rights reserved.
