“…and their use in ortopaedics and dentistry are studied. [5][6][7][8][9][10] The mechanical properties of zirconia ceramics alone coated with calcium deficient hydroxyapatite (HA) was also investigated in a more recent research. 11 The effect of oxide additions on the crystal structure vis-a-vis atom coordinates of HA is not fully understood, and they form regular composite mixtures.…”

In this study, the nanostructural vacancy behavior of bovine derived hydroxyapatite (BHA) doped with powder zirconmullite (ZM) contents of 5, 7.5, 10 and 12.5 wt.% were presented at sintering temperatures of 1000, 1100, 1200 and 1300°C. ZM‐doped BHA (ZM‐BHA) was characterized by X‐ray diffraction and positron annihilation lifetime spectroscopy (PALS). Density and hardness behavior were measured with respect to increasing sintering temperature. PALS results indicate that the longest lifetime component τ3 of ortho‐positronium (o‐Ps) localized at open spaces is attributed to the vacancy site and almost constant with the ZM contents and the sintering temperatures to have a mean value of 0.680 ns (corresponding to the radius of 0.997 nm). This average value is ascribed to the OH group defects along the main crystalline line. On the other hand, the o‐Ps intensity attributed to the number of vacancy sites increases almost linearly with ZM additives and sintering temperatures. The intensity is also related to the density and hardness of ZM‐BHA in terms of ZM contents.

Additive manufacturing (AM) is a potential engineering technique that could be used in various applications owing to its greatest advantages like flexibility in design, least expensive, versatile material synthesis and low material wastage. From various studies, it was understood that the mechanical performance of fiber-reinforced polymer composite materials (FRPCs) manufactured by AM was influenced by the process parameters to a certain extent. Additionally, numerous studies stated that the strength characteristics of the additively manufactured samples from continuous fibers, like carbon and glass, were high when compared with the samples reinforced with short fibers. Various earlier reviews enunciated that the increase in fiber volume fraction increased the strength and stiffness of the AM components many a times, while the mechanical characteristics of the samples also faced a significant increment due to the addition of fibers. Current work focuses on the influence of process parameters like process of 3D printing, materials used, layer thickness and so on upon the properties of additively manufactured FRPCs. Primary focus of the current study is to determine the effect of factors like thickness of the layer, content of the fiber in volume and the build orientation upon the properties of FRPC components manufactured by AM. This study also outlines the influence of some other parameters like loads applied, environment and analysis models on the properties of AM components along with their merits and demerits.
