On-site Replacement Part Manufacturing Proven at Sea

These printed metal tanker components would make an interesting article anyway (they have nice pics also), but the fact that they were printed on the tanker while at sea and used to make repairs to the tanker itself makes for a nice twist.

It is apparently also a world first, so that is noteworthy.

The ship in question was the Suezmax tanker Polar Endeavour, as you can see in the image below.
