Rethinking Additive Manufacturing: From Simulation to Robot-Assisted Implementation

April 15th, 2026 | by

Im Projekt FunkDAF arbeiten wir am IGMR gemeinsam mit dem Institut für Maschinenelemente und Systementwicklung (MSE) – RWTH Aachen und dem Visual Computing Institute daran, den gesamten Produktentwicklungsprozess in der additiven Fertigung ganzheitlich abzubilden – von der Bauteilgenerierung bis hin zur finalen Fertigung und Validierung.

Additive Fertigung neu gedacht: Von der Simulation zur robotergestützten Umsetzung

At the MSE, load-bearing components are created using generative design and optimized for stress through FEM analyses. Building on this stress data, the VCI develops print path-oriented strategies that are specifically aligned with the principal stress directions. This reduces anisotropic effects in additively manufactured components, improves material utilization, and significantly increases component strength.

At the IGMR, we put these innovative print paths into practice: Using a robot-assisted setup—consisting of a moving print bed and a fixed extruder—the paths are first adjusted and then converted into precise robot trajectories. The manufactured components are finally subjected to mechanical testing to validate the underlying hypotheses.

Manipulator-specific path planning for multidirectional additive manufacturing

January 20th, 2021 | by

In a joint research project between the IGMR and the ISF of RWTH Aachen University, research is being conducted on the Multidirectional Additive Manufacturing of metallic components.

With the aid of Multidirectional Additive Manufacturing (MDAM), it is possible to build complex components layer by layer and without the need for support structures. By moving the base plate by means of an industrial robot while the welding gun remains fixed, the component to be printed can always be oriented in such a way that support structures can be avoided. The major challenge lies in the consideration of specialized welding processes with external wire feeding and the use of sensors for process monitoring. This results in a dependency of the orientation of the welding gun compared to the currently printed path.
As part of his master’s thesis, Jan Wiartalla developed a path planning algorithm that calculates an executable and, if possible, continuous path within specified, flat part slices that completely fills the cross-sectional area. This is done robot-specific, so that the algorithm always takes the robot currently in use as well as its limitations into account. A standardized interface allows for the robot model to be easily exchanged and the algorithm can thus quickly be adapted to different test environments. The video illustrates the algorithm’s procedure in a simplified way.

Multidirectional Additive Manufacturing

June 26th, 2020 | by

In the new DFG project, components are manufactured with robots using wire arc additive manufacturing. Multidirectionality is to be exploited in the process.
