“…The biocompatible Ti-29Nb-13Ta-4.6Zr (TNTZ) alloy has been reported with a Young's modulus value as low as 60 GPa, compared to that of Ti6Al4V of 110 GPa [158]. However, the TNTZ alloy is also reported to have poorer strength and fatigue properties compared to Ti-6Al-4V [159]. In order to improve the mechanical properties, TNTZ has been alloyed with additions of Fe, Si, and/or O [159].…”

Biomaterials are in high demand due to the increasing geriatric population and a high prevalence of cardiovascular and orthopedic disorders. The combination of additive manufacturing (AM) and biomaterials is promising, especially towards patient-specific applications. With AM, unique and complex structures can be manufactured. Furthermore, the direct link to computer-aided design and digital scans allows for a direct replicable product. However, the appropriate selection of biomaterials and corresponding AM methods can be challenging but is a key factor for success. This article provides a concise material selection guide for the AM biomedical field. After providing a general description of biomaterial classes—biotolerant, bioinert, bioactive, and biodegradable—we give an overview of common ceramic, polymeric, and metallic biomaterials that can be produced by AM and review their biomedical and mechanical properties. As the field of load-bearing metallic implants experiences rapid growth, we dedicate a large portion of this review to this field and portray interesting future research directions. This article provides a general overview of the field, but it also provides possibilities for deepening the knowledge in specific aspects as it comprises comprehensive tables including materials, applications, AM techniques, and references.

“…Chemical composition and porosity are major parameters which affect stiffness and hardness. Different attempts to tune mechanical properties by minority alloying additions to the highly concentrated TNZT alloys have been reported, e.g., Fe [12][13][14], Si [12,13], O [12], Ag [14], Sn [14], etc. Variations of the base elements have also been studied, e.g., the Ti/Ta ratio [15,16].…”

TiNbZrTa alloys are promising for multidisciplinary applications, such as refractory and biomedical purposes, due to their high thermal stability and non-toxicity. Hardness and elastic modulus are among the key features for their adequate industrial applications. The influence of porosity and Ti/Ta ratio were investigated on TiNbZrTa alloys produced by three different processing routes, i.e., (i) blend element and posterior press and sintering (BE + P&S); (ii) mechanical alloying with press and sintering (MA + P&S); and (iii) arc melting and casting. Porosity decreased in the following order: casting < MA + P&S < BE + P&S. The total porosity of alloys increased with increasing Ta contents, i.e., by lowering the Ti/Ta ratio. However, the Ti/Ta ratio did not considerably affect the bonding energy or the elastic modulus. Hardness was increased significantly in dense alloys compared to porous ones. However, porosity and Ti/Ta ratio did not show a clear trend in hardness among the porous alloys.
