Lockheed Martin unveils largest-ever 3D-printed satellite fuel domes that can hold over 74 GALLONS

Lockheed Martin has smashed the record for the world's biggest 3-D printed part built for space. The aerospace giant built a 3-D printed titanium vessel to be used for satellite fuel tanks that measures 46 inches, or just about four feet, in diameter. Before the titanium domes, Lockheed Martin's largest 3-D printed part was a toaster-size electronics enclosure for the Advanced Extremely High Frequency satellite program. Lockheed Martin has smashed the record for the world's biggest 3-D printed part built for space. The vessel is comprised of three parts in all: two 3-D printed domes that function as caps, as well as a titanium cylinder that serves as the body of the tank.
