US Marines 3D-Printed Parts and Drones Aboard USS Essex at RIMPAC 2026

A 3D Printer on a Warship

The USS Essex (LHD-2) hosted something unusual during RIMPAC 2026: a working additive manufacturing setup that ran throughout the exercise. Marines deployed ruggedized 3D printing systems from Snowbird Technologies, a Florida-based manufacturer of field-ready production equipment, and used them to produce 316L stainless steel components and a dozen FPV drones directly on the ship's deck.

This was not a technology demonstration for show. The setup was part of a distributed manufacturing experiment led by the Naval Postgraduate School's Consortium for Advanced Manufacturing Research and Education, or CAMRE. The idea is straightforward: if the Navy can make its own spare parts at sea, it stops waiting for logistics pipelines that may not survive a contested environment.

What They Actually Printed

The numbers are worth taking seriously. Over 1,000 individual components came off the printer during the exercise, alongside 12 complete FPV drones. The parts were 316L stainless steel, chosen because it holds up to the marine environment and can replace many of the fittings, brackets, and brackets that routinely break aboard ship. FPV drones are a different use case entirely: they are time-sensitive, mission-critical, and impossible to resupply mid-deployment. Having a drone that can be printed and assembled within hours rather than waiting on a requisition changes the equation for surface warfare.

The Snowbird Technologies systems used Meltio metal wire feedstock, which reduces the safety burden compared to powder-based systems on a ship. That detail matters a great deal. Metal powder in an enclosed space with moving machinery is a fire and inhalation hazard. Wire is manageable. Haas Automation platforms and Phillips Additive integration were part of the build chain, suggesting this was industrial-grade output, not a desktop proof of concept.

Why CAMRE Is Driving This

CAMRE's role is the through line that makes this story more than a one-off stunt. The consortium connects the Naval Postgraduate School with industry and other research organizations to solve distributed manufacturing problems that individual programs cannot tackle alone. The RIMPAC trial was a controlled stress test: could field equipment produce parts fast enough to matter under operational conditions?

The answer, based on what was reported, is yes. Marines produced functional components and assembled them into systems during the exercise window. That is a meaningful data point for the Navy's additive manufacturing roadmap.

What This Means for the Industry

Military adoption of on-demand manufacturing has been talked about for years. What changed at RIMPAC 2026 is that the Navy demonstrated it at scale on an operational vessel rather than a land-based test cell. Snowbird Technologies is not a household name, but the company builds the kind of ruggedized systems designed for field conditions, not lab conditions. That distinction is the entire point.

For the broader 3D printing industry, every successful shipboard trial de-risks the business case for metal AM in the field. When the Pentagon buys something, the supply chain responds. Watch for follow-on contracts for ruggedized metal wire-fed systems from multiple vendors in the next fiscal year.
