Navy Eyes Recycled Plastic for 3D Printed Boats
28 May
Summary
- Naval boats can now be 3D printed from recycled plastic and basalt.
- The material Eclipse X9 boasts incredible strength, even at trench depths.
- Distributed manufacturing hubs could revolutionize naval logistics.
A novel approach to naval manufacturing is emerging as Voltage Vessels, a Hawaii-based company, tests 3D printed boats for defense evaluation. Utilizing a Dutch CEAD additive manufacturing system, they fabricate a 6-meter Rigid Hull Inflatable Boat (RHIB) from a unique composite.
This composite, dubbed Eclipse X9, combines recycled PETG thermoplastic with basalt fiber. The material has undergone rigorous testing validated by the University of Maine, revealing impressive tensile strength approaching 108 MPa and retaining over 90% of its structural integrity after 24 months in saltwater.
The Pentagon is exploring this technology to enhance distributed maritime operations, particularly in the Indo-Pacific. Localized 3D printing could drastically cut replacement timelines for damaged vessels, a critical advantage in contested environments and far from traditional shipyards.
