Saab Unveils AI-Designed 3D-Printed Aircraft Fuselage

Industry Insights from Next Move Strategy Consulting

In a landmark development for aerospace manufacturing, Saab has introduced a fully 3D-printed aircraft fuselage an achievement the company describes as a world-first in combining additive manufacturing, AI-driven optimisation and digital engineering at full structural scale. The five-metre demonstrator, produced using Divergent Technologies’ additive production system, is expected to undertake its first flight in 2026.

Far beyond a novel fabrication technique, Saab views the project as a foundational shift in how aircraft are designed, built and iterated. If the approach succeeds in flight testing, it could set the stage for an industrial model where structural upgrades advance with the rapidity traditionally reserved for software updates.

A Strategic Breakthrough in Design and Manufacturing Philosophy

Saab’s pursuit of rapid adaptability has long shaped its development approach, rooted in the belief that battlefield advantage hinges on the ability to observe, orient, decide and act faster. This philosophy influenced the Gripen programme’s modular structure and today’s widespread use of digital engineering.

The new 3D-printed fuselage builds upon that heritage, integrating additive manufacturing, model-based engineering and AI-powered design into a single physical structure. Saab’s shift to digital 3D definitions during the Gripen E transition eliminated reliance on paper drawings and enabled more complex geometries, providing the groundwork for its next manufacturing leap.

Gripen E’s avionics architecture further advanced this direction by separating flight-critical and mission-critical software, reducing upgrade cycles and enabling rapid software updates. Saab notes that Gripen E became “the first in-production fighter to fly with an AI agent on board in standard avionics computers,” sparking the question of whether hardware could evolve with similar speed.

Inside Saab’s Transition to Software-Defined Hardware Manufacturing

Engineers within Saab’s Rainforest innovation unit sought to merge digital flexibility with physical production, pursuing what they now call “Software-Defined Hardware Manufacturing.” The aim was to apply the same level of adaptability found in mission software to real-world structures.

Axel Baathe, head of Rainforest, described the challenge: customers using Gripen E can develop mission-critical applications in the morning and fly them in the afternoon. The question became how to deliver similar agility for hardware. Traditional factories depend on tooling, moulds and jigs constraints that add cost and time to every structural redesign.

“Software-defined manufacturing changes this,” Baathe explained, arguing that the ability to iterate without tooling enables manufacturing to keep pace with advanced design methods.

Saab and Divergent Deliver an AI-Optimized, Fully 3D-Printed Fuselage

Collaboration with Divergent Technologies brought this vision to life through the Divergent Adaptive Production System, which combines AI-driven design algorithms, laser powder-bed additive manufacturing and fixtureless robotic assembly.

The resulting fuselage was produced using 26 printed metal parts without any unique tooling and represents one of the largest additively manufactured aerospace structures intended for powered flight.

Saab highlights that traditional rules of airframe design were reimagined. Instead of ribs, spars and right-angle stringers, the structure features organic load paths generated entirely through optimisation algorithms. As Baathe noted, “It is impossible to, as a human, draw these parts,” reinforcing the necessity of AI-generated geometry.

The printed fuselage dramatically reduces part count by a factor of at least 100 and eliminates the need for thousands of rivets. The design also enables functional integration, with elements such as wiring channels, thermal management and hydraulic routing incorporated directly into the printed structure.

The fuselage has already passed structural proof loading, with flight testing scheduled for 2026 on an autonomous airborne platform currently under development.

A Reconfigurable Digital Factory for Next-Generation Aerospace

Beyond the aircraft’s structure, Saab envisions a transformation of the aerospace factory itself. Baathe describes a future where production facilities adapt automatically to any digital twin created by engineers.

“We envision that Saab’s future production factory is our most important product,” he said, outlining a model where expensive tooling is no longer a limiting factor. Saab describes the concept as “CAD in the Morning, Fly in the Afternoon,” reflecting a dramatic reduction in the cost and time associated with design changes.

This marks a departure from factory models built around decades-long production cycles. While Saab acknowledges the transition will take time, the company sees its new fuselage as proof of what could eventually become standard practice.

Implications for Future Fighters and Unmanned Platforms

Although Saab has not linked the 3D-printed fuselage to any upcoming manned fighter, the potential applications are clear. Software-defined hardware could enable rapid iterations, mission-specific airframe variants and tailor-made unmanned aircraft created for unique operational needs.

Saab emphasises that the approach “reduces the cost of change,” potentially lowering barriers to structural updates and enabling more responsive aircraft development across future programmes.

A 2026 Test Flight That Could Reshape Certification Standards

The upcoming flight test has significance well beyond Saab’s internal roadmap. While additive manufacturing has been used for brackets and secondary components, certifying primary load-bearing structures remains limited due to inspection and testing challenges.

A successful flight of a fully printed fuselage may influence regulatory frameworks, accelerating wider adoption of additive manufacturing in primary aerospace structures.

For Saab, the test will also measure how quickly physical changes can be implemented once designs are finalised a process now governed less by tooling lead times and more by algorithmic speed and robotic production.

Next Move Strategy Consulting’s View

From the perspective of Next Move Strategy Consulting, the Additive Manufacturing (AM) Market is entering a pivotal phase defined by rapid technological convergence, expanding industrial adoption and shifting production philosophies. With advancements in AI-driven optimisation, digital engineering and large-scale 3D printing exemplified by cutting-edge aerospace demonstrations the AM landscape is transitioning from prototyping toward full-scale structural manufacturing. This shift is accelerating interest across defence, aerospace, automotive, medical and industrial sectors, where organisations seek faster iteration cycles, reduced tooling dependency and highly integrated component architectures. As regulatory frameworks evolve to accommodate printed primary structures, AM is poised to become a central enabler of agile, software-defined manufacturing ecosystems. Overall, the market is expected to benefit from rising investment in digital factories, lightweighting strategies and demand for cost-efficient, customizable production models.

Redefining Industrial Strategy Through Additive Manufacturing

Saab positions the new fuselage as an early demonstration of how digital tools, AI and additive production can converge to reshape defence manufacturing. As modern conflicts and autonomous systems demand rapid iteration, the ability to update hardware as quickly as software becomes a strategic imperative.

“The joint team has done an excellent job working to prepare for first flight,” Saab announced, underscoring the milestone’s significance.

If the 2026 test succeeds, Saab and Divergent will have advanced one of the most consequential shifts in aerospace manufacturing moving aircraft production away from fixed shapes and long-term tooling, toward software-defined structures that evolve with operational needs.
