ZTM14N: Low elastic modulus
Titanium alloys are widely used for aeronautics and biomedical fields because of their superior corrosion resistance and mechanical properties. For instant, Ti64 was first used in aircraft engines during WW2. Until 1960s, Ti64 was introduced to the medical world. Today, Ti64 is widely used to manufacture medical implants using additive manufacturing, but studies have shown that vanadium and aluminum found in Ti64 represent a toxic threat to the human body and that the rigidity (High elastic modulus 110 GPa, see picture above) mismatch between the bone (25 GPa) and Ti64 is very concerning, leading to the early loosing of the implants. The most promising materials to overcome these drawbacks are the Titanium ternary alloys (See picture above)
ZTM14N belongs to ZTi-Med® powder family. It is a Titanium ternary alloy, it is a biocompatible material designed to maintain a good strength-ductility ratio. It has a very low elastic modulus (Young modulus) of 43 GPa which makes it very close to the elastic modulus of the human bone (~30 GPa). ZTM14N does not contain any toxic elements such as vanadium and aluminum found in Ti64. Because of its unique properties, ZTM14N offers a large range of applications such as medical and luxury. The powder design in addition to additive manufacturing melting process were optimized to ensure good melting conditions on all commercially available AM machines. The exceptionnel elasticity of ZTM14N makes it one of the uniques innovations in the AM industry (See video ahead). To validate the PBF process, ZTM14N powder was used to manufacture medical implants such as clavicle and maxilla implants.
