Metal Additive Manufacturing / 3D printing: An introduction

Metal Additive Manufacturing, or 3D printing, offers the possibility to produce complex parts without the design constraints of traditional manufacturing routes

Introduction to metal Additive Manufacturing and 3D Printing

Metal Additive Manufacturing, also known as metal 3D printing, offers unrivalled design freedom with the ability to manufacture parts from a wide range of materials. This is a prototype of an optimised bracket for an Airbus A380, with conventional bracket behind (Courtesy EADS)

Components that would not have even been possible just a few years ago can now be made to high standards using a wide range of metal powders. No longer solely a prototyping technology, Additive Manufacturing is now being used for the production of series components for the most demanding applications.

Additive Manufacturing, also referred to as 3D Printing, is a technology that produces three-dimensional parts layer by layer from a material, be it polymer or metal based. The method relies on a digital data file being transmitted to a machine that then builds the component.
