Lockheed Martin just made the largest 3D printed part they've ever ever built for space. The titanium domes used to take a couple of years to make from scratch, but this was completed in about three months.

Via their announcement:

The 46-inch- (1.16-meter-) diameter dome for satellite fuel tanks completed final rounds of quality testing this month, ending a multi-year development program to create giant, high-pressure tanks that carry fuel on board satellites. 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. The company shaved off 87 percent of the schedule to build the domes, reducing the total delivery timeline from two years to three months.
