“…Theoretically, BMD stainless steels can be assimilated to MIM, in terms of mechanical and corrosion resistance properties, even though the BMD have been limitedly investigated in scientific literature, to the best of the present authors' knowledge. The MIM stainless steels can reach densities of 95-97%, and mechanical properties are close to wrought materials; nevertheless, residual porosities, oxides inclusions, and carbon content can heavily affect both mechanical and corrosion resistance properties [11,12].…”

Additive manufacturing is a promising and emerging technology that can transform the global manufacturing and logistics by cutting costs and times of production. Localized corrosion resistance properties of 0°, 45°, and 90° build-up orientations of 17-4 PH as-sintered samples, manufactured by means of Bound Metal Deposition (BMD), have been investigated by electrochemical and morphological investigations. The cyclic potentiodynamic polarization curves and the open circuit potential monitoring, together with potential drop analysis, revealed that the BMD localized corrosion resistance properties were lowered if compared to a wrought 17-4 PH: a characteristic anodic behavior and many drops in potential were recorded for BMD, whilst the wrought specimens presented a typical passive behavior with pitting corrosion. Morphological investigations by scanning electron microscopy and energy-dispersive X-ray analysis revealed the presence of porosities and defects, especially for the 90° build-up orientation, and inclusions of SiO2. The 45° build-up orientation showed the best corrosion resistance properties among all the BMD specimens, even though defects and porosities were observed, suggesting that their morphology and geometry influenced the overall corrosion behavior.

For the last three decades, enormous manufacturing processes have been widely employed in the field of transportation (aviation, automobile and marine) as well as various industrial sectors. Among the invented techniques, conventional manufacturing plays a versatile and cost effective role, but additive manufacturing (AM) possesses a more significant advantage of handling complicated parts or complex geometrical structures. The conventional processes were used from ancient times until the development of other advanced techniques. In recent development of technology, AM technology has shown a tremendous change in the manufacturing field. The process of development in AM began with polymers, then to composites and advanced to nanocomposites, continuously. AM provides a waste-free production management system with enhanced processes. Therefore, this detailed and compendious review describes the different stainless steels fabricated through conventional and AM techniques. It is evident that AM proves better than other several conventional techniques, by three dimensional (3D) printing of quality and complex stainless steels components that are impossible to manufacture through other methods. Notwithstanding, there still need of much efforts to improve AM technique by reducing the manufacturing cost, supporting mass production and printing large stainless steel components.With an increase in invention of various efficient state-of-the-art engineering software, robots in manufacturing, artificial intelligence and smart manufacturing, the aforementioned drawbacks of AM technique/3D printing of various stainless steel structures will be soon eradicated.
