The US army has begun the first flight tests on aircraft parts printed with HRL Laboratories’ additive aluminum feedstock. This is the first Army-designed 3D-printed part that has ever been flown.
HRL Laboratories is commercializing its additively manufactured (3D-printed) high-strength aluminum, which has obtained the first ever registration of an additive alloy from the Aluminum Association. HRL will be granted registration number 7A77.50 for the aluminum powder used to additively manufacture the alloy, and number 7A77.60L for the printed alloy.
HRL has made a breakthrough in metallurgy with the announcement that researchers have developed a technique for successfully 3D printing high-strength aluminum alloys—including types Al7075 and Al6061.
