Abstract: Manufacturing structures mimicking the complex geometries of natural bone are in high demand in biomedical research. Additive manufacturing (AM) is an emerging technique for fabricating implant materials for biomedical applications because of its potential to achieve complex structures that are easily modulable and adaptable to human anatomy. This research paper reviews the need of switching from conventional manufacturing methods to AM and discusses some studies made on additively manufactured implants based on magnesium alloys. Although AM techniques are touted to be the more versatile manufacturing method, this paper critically communicates the shortcomings of it, in terms of process parameters, shortcomings of working with magnesium, microstructural and metallurgical defects.
