Review—Metal Additive Manufacturing of Titanium Alloys for Control of Hard Tissue Compatibility

Abstract

Metal additive manufacturing is a powerful tool for providing the desired functional performance of hard tissue biomaterials through a three-dimensional structural design. It is essential to use the interactions between living organisms and materials for functional hard tissue reconstruction. In particular, anisotropic high-performance materials that imitate bone tissue properties are required for regaining bone functionality based on collagen/apatite microstructure. This review article describes the current development of controlling hard tissue compatibility by additive manufacturing of titanium alloys, including our recent findings on the bone medical devices for guiding the anisotropic bone microstructure.

Multimetal Research in Powder Bed Fusion: A Review

“…The materials must be compatible in terms of melting points, adhesion, and reactivity, among other factors. If the materials are not compatible, it can lead to delamination, cracks, or weak bonding between the layers, thus resulting in failed prints ( Figure 7 ) [ 61 ]. The selection of materials must be based on several factors, including the intended application, the properties required for the object, and the compatibility with the printing process.…”
