DLR advances space propulsion with AdditiveLab’s simulation software
September 24, 2024
AdditiveLab BVBA, based in Leuven, Belgium, has announced that the German Aerospace Centre (Deutsches Zentrum für Luft- und Raumfahrt – or DLR) has become a customer of its advanced simulation software AdditiveLabRESEARCH. DLR is utilising AdditiveLab’s solutions to further develop next-generation space propulsion systems through Additive Manufacturing.
DLR is the Federal Republic of Germany’s research centre for aeronautics and space. Its extensive research activities cover a wide range of areas, including spaceflight, energy, transport, security, and digitalisation. DLR’s Institute of Materials Research, based in Cologne, focuses on the development of new materials, from alloy design to demonstration at component scale.

One of the core motivations behind DLR’s adoption of AdditiveLab software is reported to be for the development of complex components such as internal cooling channels in rocket engines, critical for spaceflight applications. This advancement is said to represent a key step forward in space propulsion technology.
Simulation for enhanced material knowledge and reduced development cycles
By leveraging AdditiveLab’s simulation capabilities, DLR can better understand the laser-material interactions that occur during the manufacturing process. This includes precise control and tailoring of microstructures in various materials, such as titanium, aluminium, nickel-based alloys, copper, and even high-entropy alloys.
The insight gained from these simulations allows DLR to refine the material properties of these components to meet the unique demands of spaceflight.
Another benefit of utilising AdditiveLab software is the ability to predict pre-deformation and identify critical thermal hotspots before the actual build-up process begins. This predictive capability is expected to enable DLR to significantly shorten development cycles and reduce the number of physical prototypes required, improving both time efficiency and cost-effectiveness in their projects.
