Experts build pulsed air rig to test 3-D printed parts for low carbon engines

The rig uses fresh air instead of hot exhaust gas, so the 3-D printed plastic parts won't melt under the usually hot conditions found in normal engine test facilities.
It also means makers can 3-D print only the parts of the engine that need testing, instead of building a whole engine.
