The USS Essex, a Wasp-class Landing Helicopter Dock (LHD), recently loaded a new 15,000-pound 3D printer, just prior to departing to participate in the multinational Rim of the Pacific exercise underway at Hawaii and California. The amphibious assault ship will be the first to test the new 3D printer during underway conditions at sea.
Unlike previous 3D printers tested by the Navy that print objects using polymers or metal powders, the Xerox ElemX 3D printer uses aluminum wire to create parts and tools.
Lt. Cmdr. Nicolas Batista, the Aircraft Intermediate Maintenance Department (AIMD) officer aboard Essex stated that the new 3D printer is one of the fastest printers on the market, capable of fabricating and printing aluminum up to 10” by 10”. Many common components may be created on the ship to include heat sinks, housings, fuel adapters, bleed air valves, valve covers and more.
The 18′ foiling catamaran seen recently flying over the waves off the coast of Essex in the UK, was a small boat testing a very big concept. As it flew during the two-hour sea trial, the boat drove an underwater turbine that generated electricity which then used electrolysis to split seawater into hydrogen and oxygen.

The bad news is that there have been three reported shark attacks off New York’s beaches in just over a week. The good news is that the injuries, so far, have been minor. Nevertheless, beaches in New York and along the Jersey Shore are on high alert, flying red flags near beach signs and purple flags in lifeguard areas to alert visitors of the potential danger. Lifeguards are patrolling on paddle boards and jet skis, while overhead, helicopters and drones are helping to watch for sharks.
