1-Meter 3D Printable Model
The Triomphant-class represents the pinnacle of French naval engineering — a fleet of four nuclear-powered ballistic missile submarines that form the backbone of France’s sea-based strategic deterrent. Commissioned between the late 1990s and early 2010s, these vessels — Le Triomphant, Le Téméraire, Le Vigilant, and Le Terrible — embody decades of design evolution in stealth, endurance, and acoustic refinement. Their quiet hydrodynamic profiles and robust reactor systems enable long, independent patrols beneath the ocean surface, ensuring both national defense and strategic balance.
This 3D modeling project translates that formidable maritime presence into a detailed, buildable digital form. At 1 meter in length, the model captures the Triomphant-class’s refined geometry — its continuous curved hull, distinctive missile deck, and smoothly blended sail structure. The digital design emphasizes proportion, hull accuracy, and printability, resulting in a form that is both visually authentic and structurally reliable when printed. The streamlined shape of the Triomphant-class lends itself naturally to 3D fabrication, and this model takes full advantage of that efficiency, balancing elegance with mechanical integrity.

To make the design accessible to a wide audience, two free versions of the one-piece display model have been released. The Thingiverse edition provides an easy-to-print version for most consumer 3D printers, requiring minimal slicing preparation and no assembly. For users seeking greater definition and finer surface curvature, a free high-poly version is available exclusively on my website, offering superior smoothness and print resolution. Both files share the same overall form, ensuring consistent proportions and compatibility across platforms, while the website version offers improved visual fidelity for high-quality display printing.
For experienced builders and professional hobbyists, a premium multi-part high-poly edition of the Triomphant-class is also available. This version divides the model into multiple precision-engineered sections, optimized for FDM printing at 0.16–0.20 mm layer height with 15–20% infill, minimizing support material and improving finish consistency. The separation of components allows for custom painting, easier handling of large prints, and potential RC conversion for those who wish to explore functional adaptations. Wall thickness averages 4–6 mm, providing structural rigidity and buoyancy potential without compromising scale realism.
The Triomphant-class 1-Meter 3D Printable Model stands as both a technical project and a tribute to modern submarine design — a representation of silent strength, precision engineering, and digital craftsmanship. Whether downloaded freely for display or assembled from the full high-poly kit, the model offers builders a way to engage directly with one of the most sophisticated submarine classes ever built. It reflects not only the legacy of the French deterrent fleet but also the creativity and accessibility that modern 3D modeling brings to naval heritage. You can download the free STL file below. If you enjoy the model, please consider supporting the site by purchasing the full high-detail version.
