Iron has been vigorously studied as a potential biodegradable bone scaffold in the past decade due to its appealing mechanical strengths and biodegradability. Nevertheless, its high potential as temporary medical implants could be hampered as its biocorrosion kinetics are still considered too slow in both in vitro and in vivo environments, which are not tailored to tissue healing time. Various approaches have been applied to expedite Fe corrosion, and one of them is making Fe porous structures in topologically ordered design via additive manufacturing (AM) techniques. AM techniques are an advanced approach to producing porous Fe-based scaffolds with high porosity, controllable pore structure and size, and a final intricate design to meet the corrosion and biocompatibility requirements. The present review discusses the current development of porous Fe scaffolds produced by AM techniques and the effects of the designs and AM processing on the corrosion properties and the biocompatibility of the developed AM porous Fe. This review provides great insights into the current performance of AM Fe in terms of corrosion behaviour and the cell-material interactions for potential AM bone scaffolds. © 2024
