The machine uses powdered metal and a laser, essentially welding the dust into shapes detailed by a complicated computerized design. Constructing one 40-micron-thick layer at a time, it can produce any metal object that will fit into a build envelope that's slightly smaller than 10x10x12 inches.

The technology soon will enable manufacturers to produce complex geometries that aren't now possible using traditional production methods - and to make things more quickly, using less material.

CIRAS believes helping companies experiment and test the boundaries of additive manufacturing will position Iowa to make maximum advantage of a coming wave of change. It's all part of an ongoing mission CIRAS has had since 1963 - to advance Iowa communities by making their businesses better.

"Is this technology ready for everyday use? No," summarizes Chris Hill, head of CIRAS' Technology Assistance Program. "But if I as a manufacturer can start getting educated now, then I kind of know what I can do with it. And when the technology gets a little better, then I can take advantage of it while my competitors are still thinking, 'OK, now I need to start learning about this...' "
