Additive manufacturing (AM) is one of the critical techniques of novel medical devices which is capable of processing complicated or customized structures to best match the human’s bones and tissues. AM allows for the fabrication of devices with optimal architectures, complicated morphologies, surface integrity, and regulated porosity and chemical composition. Various AM methods can now consistently fabricate dense products for a range of metallic, nonmetallic, composites, and nanocomposites. Different studies are available that describe the microstructure and various properties of 3D-printed biomedical alloys. However, there are limited research on the wear characteristics, corrosion resistance, and biocompatibility of 3D-printed technology-constructed biomedical alloys. In this article, AM metallic biomaterials such as stainless steel, magnesium, cobalt–chromium, and titanium are reviewed along with their alloys. The helicopter view of essential characteristics of these additively manufactured biomaterials is comprised. The review will have a significant impact on fabricating metallic surgical equipment and its sturdiness in the biomedical field.
