Characterization of grade 2 commercially pure Trabecular Titanium structures

Laser and electron‐beam powder‐bed additive manufacturing of metallic implants: A review on processes, materials and designs

“…Most research on titanium and its alloys is driven by its potential application as body prostheses due to their biocompatibility. Ti6Al4V are of high interest because of their applications in both aerospace and biomedical industries . This group of metallic materials has been widely used for various orthopaedic implants due to their good biocompatibility, superior corrosion resistance and high mechanical strength .…”

“…Ti6Al4V are of high interest because of their applications in both aerospace and biomedical industries. 64,65 This group of metallic materials has been widely used for various orthopaedic implants due to their good biocompatibility, superior corrosion resistance and high mechanical strength. 38, 66 Moreover, they have high specific strength and elastic moduli closer to bone than CoCr alloys and stainless steel.…”

Influence of the overall stiffness of a load-bearing porous titanium implant on bone ingrowth in critical-size mandibular bone defects in sheep

“…However, increased porosity and pore size implies reduction of the mechanical strength and stiffness that can be critical for the reconstruction of load-bearing bones. Sintering or melting of titanium powders allows 3D-printing of complex structures, including porous structures with precisely controlled microarchitecture (Barbas et al, 2012;Marin et al, 2013;Otawa et al, 2015). The scaffold can thus be designed to replicate the outer shape of the missing bone and its mechanical response can be adapted to the functional loading.…”

Preparation of weak-textured commercially pure titanium by electron beam melting

“…In contrast, the EBM-prepared components exhibited almost completely isotropic tensile properties. Although Arcam AB has already provided CP Ti Grade 2 as a commercial fabrication material for their systems and a few reports on this material have been published (e.g., [21]), this paper presents the first report on the development of weak-textured microstructures and resulting isotropic tensile properties in EBM-fabricated CP-Ti. It should also be noted that, compared with conventional CP-Ti Grade 2, the EBM-prepared CP-Ti represented much higher strength 1 Although the as-EBM-built samples can be categorized as ASTM Grade 1, their oxygen concentration is relative high (0.15%) and is close to the upper limit of the Grade 1 standard (≤ 0.18%).…”
