Abstract 3D printing (3DP) technologies have transformed the processing of advanced ceramics for small‐scale and custom designs during past three decades. Simple complex parts are designed manufactured using 3DP structural, piezoelectric, biomedical applications. Manufacturing simple or geometries one‐of‐a‐kind components without part‐specific tooling saves significant time creates new applications ceramic materials. Although development innovations in far behind compared with metals...
Commercially pure titanium (CpTi), a bioinert metal, is used as an implant material at low load-bearing sites and porous coating on Ti6Al4V high sites. There unmet need for metallic biomaterials to improve osseointegration inherent antimicrobial resistance. In this study, we have added 1 wt % SiO2 3 Cu the CpTi matrix processed via metal additive manufacturing (AM). Si4+ ions promote angiogenesis osteogenesis. CpTi-SiO2 composition exhibited 4.5 times higher bone formation bone–implant...
Bacterial colonization of orthopedic implants is one the leading causes failure and clinical complexities for load-bearing metallic implants. Topical or systemic administration antibiotics may not offer most efficient defense against colonization, especially in case secondary infection, to surgical removal some cases even limbs. In this study, laser powder bed fusion was implemented fabricate Ti3Al2V alloy by a 1:1 weight mixture CpTi Ti6Al4V powders. Ti-Tantalum (Ta)-Copper (Cu) alloys were...
This study measured the tensile, compression, and fatigue behavior of additively manufactured Ti3Al2V as a function build orientation. alloy was prepared by mixing commercially pure titanium (CpTi) Ti6Al4V in 1:1 wt. ratio. Laser powder bed fusion (L-PBF) based additive manufacturing (AM) technique used to fabricate samples. Tensile tests resulted an ultimate strength 989 ± 8 MPa for Ti3Al2V. 90° orientation samples showed compressive yield 1178 33 MPa, that 968 24 MPa. Varying account...
Alloy design coupled with metal additive manufacturing (AM) opens many opportunities for materials innovation. Investigating the effect of printing parameters alloy is essential to achieve good part quality. Among different factors, laser absorptivity, heat diffusivity, and in situ intermetallic phase formations are critical. In this study, first step employed was a reduction Al V contents Ti6Al4 Ti3Al2 alloy, further 10 wt.% tantalum (Ta) 3 copper (Cu) were added V. A synergistic Ta Cu...
The bio-inertness of titanium, which is the ultimate choice metallic material for implant applications, causes delayed bone–tissue integration at site and prevents expedited healing patient. This can result in a severe issue patients with immunocompromised bone health as titanium does not offer inherent antimicrobial properties, thus, infections are another concern. Current strategies addressing issues above include using cemented implants coating on Ti6Al4V bulk orthopedic...
