Additive manufacturing has profoundly changed the design, testing and production process for parts used in the aerospace sector. This industry benefits not only from reduced production times, but also from improved characteristics of the parts manufactured. In this context, SAB Aerospace has developed the first demonstration model of one of its rocket nozzles, using Prima Additive’s DED (directed energy deposition) technology.
In keeping with Prima Additive’s philosophy, “Crafting the Future of Space One Layer at a Time,” this nozzle design represents a breakthrough for the conduct of space missions. Indeed, the rocket nozzle is an essential part of the engine. It is mainly used to channel the hot gases generated during fuel combustion. The integration of DED technology brings an improvement to nozzle manufacturing. This process, which used to be complex and often time-consuming, is now more efficient thanks to this method. But why choose this technology?

SAB Aerospace Relies on Inconel® and 3D Printing for Rocket Nozzles
SAB Aerospace has adopted DED technology to simplify the manufacturing of large metal parts. Unlike processes such as SLS or FDM, which require a closed chamber and are limited by its dimensions, DED enables large parts to be produced without being restricted by the size of the machine.
