AFRL entwickelt erste 3D-gedruckte Schubkammer für Raketentriebwerke – Das US Air Force Research Laboratory (AFRL) hat seine erste additiv gefertigte Schubkammer für Raketentriebwerke hergestellt.

From the article

>Additive manufacturing is similar to industrial 3D printing, which uses different materials to mold product segments.

>For AFRL’s project, experts applied laser powder-directed energy disposition (DED) to build the chamber, an approach leveraging metal powder injection as base material and a high-power laser to construct the part in a temperature-controlled environment.

>“It provides the largest build box volume for thruster hardware to date, capable of printing seven-foot-tall parts,” AFRL Combustion Devices Chief Dr. **Javier Urzay** [explained](https://www.afrl.af.mil/News/Article-Display/Article/3749659/afrl-researchers-pave-the-way-to-lighter-faster-additively-manufactured-rocket/).

>“DED enables an order of magnitude less investment in powder and less material waste. Engineers can also realize alloy blending and transitions in real time for multi-alloy builds to exploit the strength, weight and performance gains of next-generation superalloys.”
