Saab has collaborated with Divergent Applied sciences to develop what the businesses describe because the world’s first software-defined plane fuselage utilizing additive manufacturing. The 5-meter-long construction contains 26 distinctive printed elements and was produced with out conventional tooling or fixturing. As an alternative, the undertaking utilized Divergent’s manufacturing platform that mixes industrial laser powder fusion 3D printing with robotic meeting.
The fuselage represents a part of Saab’s broader initiative known as “Software program-Outlined {Hardware} Manufacturing,” led by the corporate’s inside innovation unit, The Rainforest. “We’re asking ourselves the query – In Gripen E clients get a platform the place they’ll code mission-critical functions within the morning and fly them within the afternoon. How can we give them the identical degree of software program flexibility, however for precise {hardware}?” stated Axel Bååthe, Head of The Rainforest.
In line with Saab, the additive manufacturing method permits load-bearing constructions to observe optimum load paths reasonably than conventional straight traces and proper angles. The corporate states this methodology can scale back the variety of elements in a fuselage by an element of 100 in comparison with standard riveted assemblies. The know-how additionally permits integration of techniques like wiring and thermal administration immediately inside the printed construction.
The fuselage has accomplished structural proof-loading checks and is scheduled for flight testing in 2026. This undertaking builds on Saab’s use of model-based engineering strategies in growing its Gripen E fighter plane, which the corporate says pioneered digital twin know-how in aerospace design and manufacturing. Saab’s objective is to attain what it calls “CAD in The Morning, Fly in The Afternoon” manufacturing functionality.
