3D Printed Boat Boosts Naval Innovation in the Netherlands

In a previous analysis of 2025 3D printing trends, we mentioned how the defense sector is showing increasing interest in additive manufacturing, to the point of integrating it as a key technology in its operations. A new application for the Navy in the Netherlands is reaffirming this trend. It’s called the SeaRush project, a functional prototype of a 3D-printed unmanned boat, which marks a new advance in the development of unmanned surface vessels (USVs).

The initiative was driven by the Maritime Research Institute Netherlands (MARIN), in collaboration with the MIND Innovation Center. The development of the prototype responds to the need for USVs that can be designed and deployed quickly, while keeping costs under control and allowing for continuous iterative improvements. In a context of growing international tensions and personnel constraints in navies, according to MARIN, SeaRush seeks to demonstrate that it is possible to move from concept to a fully operational system in a very short time frame.

The prototype was made possible thanks to close collaboration throughout the entire production chain. IMPACD Boats was responsible for transforming the conceptual design into a model suitable for 3D printing, while CEAD contributed its expertise in large-format additive manufacturing for the maritime sector. The hull was printed in less than a week at the Dutch Boat Factory in Delft, and the equipment was then completed as a fully operational USV in Woudsend. The propulsion system integrates a Honda outboard motor, connected to a control system developed in collaboration with the Italian company UltraFlex, which allows for remote operation.
