NASA tests limits of 3-D printing with powerful rocket engine check

The largest 3-D printed rocket engine component NASA ever has tested blazed to life Thursday, Aug. 22 during an engine firing that generated a record 20,000 pounds of thrust. This test is a milestone for one of many important advances the agency is making to reduce the cost of space hardware. Innovations like additive manufacturing, or 3-D printing, foster new and more cost-effective capabilities in the U.S. space industry.
