Additive Manufacturing (AM) is one of the pillars of the fourth industrial revolution that is becoming embraced globally. AM comprises of producing objects layer by layer from a three-dimensional computer-aided system. It also is a disruptive technology that offers sustainability through improved productivity and resource-efficient processes. These are key elements of a green economy and competitive manufacturing. A green economy refers to industrial processes with low carbon emission, minimum waste of resources and social practices that do not degrade the environment. In the context of this paper, the green economy is defined as production technologies that are aimed at reducing environmental risks while promoting resource efficiency. This paper provides a review of AM as a viable industrial technology for a green economy. It explores possible AM strategies for metal production to point out that AM technologies can be more sustainable than traditional metal casting technologies.
