“…The most typical applications are implants (Ti64, Co-Cr-Mo [50] ,

ceramic [51] ) and prostheses (Co–Cr alloys, CP Ti, and Ti–6Al–4V [52] ). Selective laser sintering (SLS) [53] , [54] , [55] , [56] , [57] , electron beam fusion (EBM) [58] , [59] and selective laser melting (SLM) [60] , [61] belong to this category. Regarding the innovations based on this category, some areas need further development, such as 3DP of porous metallic structures used as implants in the body.…”

This review focuses on the advancements in additive manufacturing techniques that are utilized for fabricating bioceramic scaffolds and their characterizations leading to bone tissue regeneration. Bioscaffolds are made by mimicking the human bone structure, material composition, and properties. Calcium phosphate apatite materials are the most commonly used scaffold materials as they closely resemble live bone in their inorganic composition. The functionally graded scaffolds are fabricated by utilizing the right choice of the 3D printing method and material combinations to achieve the requirement of the bioscaffold. To tailor the physical, mechanical, and biological properties of the scaffold, certain materials are reinforced, doped, or coated to incorporate the functionality. The biomechanical loading conditions that involve flexion, torsion, and tension exerted on the implanted scaffold are discussed. The finite element analysis (FEA) technique is used to investigate the mechanical property of the scaffold before fabrication. This helps in reducing the actual number of samples used for testing. The FEA simulated results and the experimental result are compared. This review also highlights some of the challenges associated while processing the scaffold such as shrinkage, mechanical instability, cytotoxicity, and printability. In the end, the new materials that are evolved for tissue engineering applications are compiled and discussed.

“…Transition metals currently make up a large proportion of suitable dopants due to the medical benefits they provide. Elements like iron (Fe), copper (Cu), magnesium (Mg), and zinc (Zn) that already play vital roles within the human body are the focus of these studies [21,[26][27][28][29][30]. Similar interest has also been directed toward the rare earth elements.…”

“…Fe ions have been revealed to enhance the bone metabolism process which is why they were considered as potential doping candidates into bioactive glasses. Fe-doped bioactive glasses have characteristically lower crystallization temperatures than their non-doped counterparts and also have greater storage modulus values [27]. This is turn correlates to larger elastic modulus values for Fe-doped bioactive glasses, making them more suitable for implantation applications into the human body [25].…”

Increasing popularities of bioactive-glasses and their potential medical applications have led to countless studies into improving their material characteristics and overall performance. Some scientists hope to create new bioactive-glass compositions, while others seek to merely modify existing ones such as the novel 45S5 bioactive-glass composition; created by Dr. Larry Hench. These modifications aim to address potential complications that may arise at a site following implantation such as bacterial infections. In other cases, the incorporation of a selected element or compound may aim to improve the implant functioning by increasing cell proliferation. Although possibilities are plentiful, researchers avoid compromising the typical bioactive glass characteristics when doping with elements such as silver, or gold to achieve additional properties. This chapter elaborates on the incorporation of popular elements by doping bioactive-glass compositions to introduce desired properties based on the implant application.
