“…Furthermore, additively manufactured titanium alloys have been considered in the field of biomedical engineering [ 97 , 98 ], however, the selective laser melting process introduces high surface roughness due to partially melted particles which limits their use as hip implants [ 99 ]. Ghosh et al [ 99 ] have therefore, modified the surface of the fabricated titanium implants with 2-methacryloyoxyethyl phosphorylcholine polymer. It was crucial to achieve a homogenous graft of the polymer on the implant surface, to minimise the friction and wear impact.…”

Additive manufacturing (AM) is a rapidly expanding material production technique that brings new opportunities in various fields as it enables fast and low-cost prototyping as well as easy customisation. However, it is still hindered by raw material selection, processing defects and final product assessment/adjustment in pre-, in- and post-processing stages. Spectroscopic techniques offer suitable inspection, diagnosis and product trouble-shooting at each stage of AM processing. This review outlines the limitations in AM processes and the prospective role of spectroscopy in addressing these challenges. An overview on the principles and applications of AM techniques is presented, followed by the principles of spectroscopic techniques involved in AM and their applications in assessing additively manufactured parts.

“…202 Ghosh et al also modified the commonly used a titanium alloy (Ti6Al4V) with an MPC polymer with a uniform surface, less roughness, and low cell attachment to fulfill the requirement of hip arthroplasty. 203 Implantable glucose sensors are very useful for monitoring the blood glucose level of diabetics; however, they still lack in vivo long-term reliability owing to the inflammation and fibrosis around the sensors, which both decrease their sensitivity (blocking glucose transportation) and shorten their lifetime. To address this problem, Wang et al developed a hydrogel coating incorporated with pH-sensitive molecularly imprinted polymer (MIP) nanospheres.…”

“…In this regard, SLM has been widely used to fabricate the implant with a complex structure that patients need directly. Extensive studies have been reported, showing that the titanium-based implants produced by SLM exhibit excellent mechanical properties, compared with their traditionally manufactured counterparts [ 15 ], resulting from the rapid solidification-induced refined microstructure [ 16 , 17 ]. F.B et al confirmed that, due to the high cooling rate, the presence of harder microstructural constituents in Ti6Al4V, produced by SLM, leads to a higher wear resistance than hot pressing and casting specimen [ 18 ].…”

Metallic elemental powder mixture and pre-alloyed metallic powder are both frequently used powder feedstock in the additive manufacturing process. However, little research has been conducted to compare the corrosion behavior of selective laser melting (SLM) alloys, fabricated by pre-alloyed metallic powder and mixed metallic powder. Hence, it is important to investigate the corrosion behavior of SLMed alloys, as well as the corresponding cast ingot, with the aim to better understand the feasibility of designing new materials. In this work, the SLM-produced Ti6Al4V3Cu alloys were manufactured using a metallic elemental powder mixture and pre-alloyed metallic powder, respectively. The corrosion behavior of the different Ti6Al4V3Cu alloys was investigated in following electrochemical tests and ion release measurements. The results showed that the Ti6Al4V3Cu alloy prepared by pre-alloyed metallic powder showed better corrosion resistance than that produced from mixed metallic powder. Moreover, the SLM-produced Ti6Al4V3Cu alloys performed significantly better in corrosion resistance than the cast Ti6Al4V3Cu. The results are expected to achieve a better understanding of the feasibility of designing new materials using mixed powders, contributing to reducing development costs and cycles.
