A functional 25-horsepower outboard motor is one of the boldest examples of what 3D printing enthusiasts can accomplish. This project goes far beyond novelty or display. It is designed to handle the ...

Every component on a nuclear sub is important, and a Virginia-class submarine called the Oklahoma is getting a 3D-printed drain assembly.

Six engineering students at The University of Warwick have built a 3D printed submarine using a Stratasys Fortus 3D Printer. The submarine is set to r ...

A 3D-printed submarine? Not likely, but maybe something close The Navy is bumping up its use of additive manufacturing to make critical, delay-prone submarine parts, said Christopher Miller ...

The Navy’s nuclear-powered warships increasingly will be made of 3D printed parts, which are cutting costs and reducing production time on billion-dollar ships that are years in the making. H… ...

Only 3D printing can get the Navy’s submarine plan back on track, admiral says U.S. cannot build and support the subs it needs “without going to additive manufacturing.” ...

The part printed is a deck-drain, and it was manufactured on land out of copper-nickel. The part still needs some machining to refine it before it is installed, but the printing of a replacement ...
