Osseointegration Effects of 3D-Printed Porous Titanium-Tantalum Scaffolds with Different Tantalum Contents.

ABSTRACT: Titanium (Ti) is known for its excellent corrosion resistance and its biomechanical properties. However, its bioinert nature and high elasticity result in suboptimal osseointegration. In contrast, tantalum (Ta) demonstrates superior osteogenesis and osseointegration but has a high elastic modulus and density, making it costly to process. In the present study, we produced the implantable composite TiTa that combines the advantages of Ti and Ta, which is fabricated by blending Ti powder with 25, 50, and 75% Ta. We designed porous scaffolds with different TiTa ratios while maintaining consistent porosity, pore shape, pore size, and distribution via computer-assisted design (CAD) and fabrication through laser powder bed fusion (LPBF). The results show that the elastic modulus and yield stress
