3D Printed Titanium Alloy in Bone Repair

Abstract

Today, with more and more cases of bone injury around the world, people are now in need of efficient bone care. The 3D printing technique has found wide application in the field of bone restoration. Metallic materials are widely used in clinic, and Ti alloy is a good medical material for its outstanding properties. The advantages and disadvantages of 3 main 3D-printing techniques for metals are discussed, including selective laser melting (SLM), electronic beam melting (EBM) and binder jetting (BJG). Therefore, 3 kinds of powder technology suitable for Ti alloy are presented, including plasma rotating electrode process (PREP), gas atomization (GA) and plasma atomization (PA). In addition, the presentation and optimal application of 3D printed Ti alloys in the treatment of bone diseases are also discussed. Through a review of the latest advances in relevant areas, this article will offer valuable data and instruction to apply 3D printing to bone treatment.
