Lockheed is 3D printing titanum fuel tank for Lockheed Martin’s largest satellites. Using this manufacturing method, tank delivery time went down from two years to three months (nine times faster) and they are no longer wasting 80% of the materials.
The titanium tank consists of three parts welded together: two 3-D printed domes that serve as caps, plus a variable-length, traditionally-manufactured titanium cylinder that forms the body.
Satellite fuel tanks must be both strong and lightweight to withstand the rigors of launch and decade-long missions in the vacuum of space. That makes titanium an ideal material, but procuring 4-foot-diameter, 4-inch-thick titanium forgings can take a year or more, making them the most challenging and expensive parts of the tank. Traditional manufacturing techniques also meant that more than 80 percent of the material went to waste. Now, 3-D printing eliminates all that lost material for the domes, and the titanium used for printing is readily available with no wait time.
