launched aggressive investments in the technology, with one effort involving $245 million over a period of six years. Meanwhile, Singapore is pouring $400 million into advanced manufacturing, which includes AM. Taiwan and South Korea recently announced multi-million dollar investments in AM technologies, joining governments in Australia, Europe, South Africa, and the US that are investing in the technology. The investment community has taken a real shine to AM, although stocks from publicly traded AM companies have experienced volatility in 2014. Even so, investors are determined to better understand the products, companies, and trends surrounding this dynamic and intriguing industry.


Rock-Solid Growth in 2013 Despite some uncertainty, the long-term outlook for the AM industry remains very strong. Total revenues from all AM products and services worldwide grew 34.9% in 2013 to $3.07 billion, according to research for Wohlers Report 2014. The AM industry’s compound annual growth rate for the


past 25 years is an impressive 27%. The CAGR over the past three years (2011–2013) is 32.3%. Regardless of the volatile stocks, misleading articles, and often overhyped capabilities of the technology, AM is an industry that is emerging from its awkward adolescence with solid growth and a strong founda- tion for further maturation.


The Sky’s the Limit A big part of that maturation rests with the aerospace


industry. Boeing has installed environmental control system ducting made by AM for its commercial and military aircraft for many years. In fact, tens of thousands of AM parts are fl ying on 16 different production aircraft—both commercial and military. The real bellwether event was GE Aviation’s 2013


This chart provides revenues (in millions of dollars) for AM products and services worldwide. As you can see, the past four years are up signifi cantly from previous years, and the market has nearly tripled over this period of time.


announcement that it would be using AM to print a very seri- ous metal part for jet engines. The company has committed to using AM to manufacture more than 30,000 fuel nozzles annually for its new LEAP engine starting in 2015. The new design consolidates 18 parts into one, and is 25% lighter and fi ve times more durable than the previous fuel nozzle.
