The present study evaluates the corrosion behavior of poly[xylitol‐(1,12‐dodecanedioate)](PXDD)‐HA coated porous iron (PXDD140/HA‐Fe) and its cell‐material interaction aimed for temporary bone scaffold applications. The physicochemical analyses show that the addition of 20 wt.% HA into the PXDD polymers leads to a higher crystallinity and lower surface roughness. The corrosion assessments of the PXDD140/HA‐Fe evaluated by electrochemical methods and surface chemistry analysis indicate that HA decelerates Fe corrosion due to a lower hydrolysis rate following lower PXDD content and being more crystalline. The cell viability and cell death mode evaluations of the PXDD140/HA‐Fe exhibit favorable biocompatibility as compared to bare Fe and PXDD‐Fe scaffolds owing to HA's bioactive properties. Thus, the PXDD140/HA‐Fe scaffolds possess the potential to be used as a biodegradable bone implant.

“…The combination of multiple strategies might be a very promising route to design novel Fe-based materials for resorbable implants. Recently, there has been a significant surge in interest surrounding Fe-based biocomposite, prepared by incorporating a secondary compound into Fe matrix, such as CaCl 2 , CaSO 4 , MnO [ [106] , [107] , [108] ]. These compounds, serving as source of Cl − ion releasing (CaCl 2 ) and micro-acidification (CaSO 4 ), or catalyst to promote oxygen reduction reaction (MnO 2 ), could increase the corrosion rate of Fe.…”

This paper conceptualises an understanding of advanced manufacturing methods to develop 3D-printed metallic orthopaedic implants, including a brief discussion on post-process machining. The significance of Metallic Additive Manufacturing (MAM) and its practicality for industrial applications is discussed through a juxtaposition with conventional casting and machining approach. Different alloys and suitable MAM techniques are thoroughly reviewed to determine optimum operating conditions. Although MAM can produce near-net shape parts, post-processing is an unavoidable requirement to improve surface quality and dimensional accuracy. A comparative study is presented, highlighting the importance of machining for post-processing in terms of cost savings and performance. Different materials are evaluated aiming to overcome problems associated with existing orthopaedic implants. The consequence of bone-implant mechanical mismatch leading to stress shielding and inadequate corrosion properties obstructing biodegradability are explored in detail. The effect of additive manufacturing parameters on mechanical, corrosion, and surface properties including biocompatibility is analysed. Evidence of MAM’s advantages over conventional manufacturing approaches, such as the use of functionally graded lattices and patient-specific customised designs, is also presented. Finally, for future studies, a two-way approach is conceptualised with material selection and manufacturing process control in progressions of implant development using MAM. Graphical Abstract
