Disruptive technology of additive manufacturing

Additive manufacturing could radically change the way in which many products are made and distributed. It fabricates components directly from 3D computer models by selectively depositing, curing, or consolidating materials one layer upon the next. It has state of the art applications. Additive manufacturing is already a valuable tool for surgeons to better understand unique, intricate anatomical relationships that are difficult to visualise using two-dimensional images.

Overview of current additive manufacturing technologies and selected applications

ABSTRACT
Three-dimensional printing or rapid prototyping are processes by which components are fabricated directly from computer models by selectively curing, depositing or consolidating materials in successive layers. These technologies have traditionally been limited to the fabrication of models suitable for product visualization but, over the past decade, have quickly developed into a new paradigm called additive manufacturing. We are now beginning to see additive manufacturing used for the fabrication of a range of functional end use components. In this review, we briefly discuss the evolution of additive manufacturing from its roots in accelerating product development to its proliferation into a variety of fields. In this article, we focus on some of the key technologies that are advancing additive manufacturing and present some state of the art applications.
