It’s been five or so years since 3D printing was at peak hype. Since then, the technology has edged its way into a new class of materials and started to break into more applications. Today, 3D printers are being seriously considered as a means to produce stainless steel 5G smartphones, high-strength alloy gas-turbine blades, and other complex metal parts.

The technology for 3D printing (or additive manufacturing) of metals is finally hitting its stride. Two industries—aerospace and medical appliances—have already adopted it. Lawrence Gasman, president of Charlottesville, Va.–based industry analyst SmarTech Publishing, says, “There are no big aerospace companies that don’t use 3D printing for major parts in their aircraft. Obviously, there are some things that will never be 3D-printed, but it’s quite remarkable how much actually is.”

Asad Madni and the Life-Saving Sensor

In 1992, Asad M. Madni sat at the helm of BEI Sensors and Controls, overseeing a product line that included a variety of sensor and inertial-navigation devices, but its customers were less varied—mainly, the aerospace and defense electronics industries.

And he had a problem.

The Cold War had ended, crashing the U.S. defense industry. And business wasn’t going to come back anytime soon. BEI needed to identify and capture new customers—and quickly.
