ADDITIVE manufacturing (AM), more popularly known as 3D printing, describes a group of technologies used to produce objects through the addition of material rather than its removal. AM first became commercially viable in the mid-1980s. Its first widespread applications were in the production of prototypes, models, and visualization tools. More recently, however, advances in printer and materials technology have allowed AM to expand to other applications such as tooling and end-user part production. AM is used in many industries, including aerospace and defense, automotive, consumer products, industrial products, medical devices, and architecture. The overall market size for the AM industry was estimated at $2 billion in 2012, and it is growing at a compound annual growth rate (CAGR) of 14.2 percent.
