Recent Advancements in Additive Manufacturing (AM) Techniques: A Forward-Looking Review

We witness noteworthy developments in multifunctional materials progress through additive manufacturing techniques, enhanced by the revolution of Industry 4.0 and Internet of Things. Still, in specific circumstances, the performance of used materials is sometimes limited. Among the various existing techniques, the additive manufacturing (AM) process has gained much popularity over the last two decades and is one of the most revolutionary manufacturing techniques. In this comprehensive review, we have addressed the fundamentals of various Additive Manufacturing processes, including binder jetting, fused deposition modelling, Stereolithography, selective laser sintering/melting, direct energy deposition. Furthermore, recent advancements and emerging new technology in AM domain named electrochemical additive manufacturing is highlighted in this review as a major part. These processes’ capabilities, advantages, limitations, and applications are also discussed. In the concluding sections of this work, future trends are offered and discussed. Graphical Abstract
