Laser and powder-based Directed Energy Deposition

DED based on laser and powder (DED-LB/p) enables the processing of a wide variety of materials. The powder composition can be further varied to achieve, for example, graded material properties.

Fraunhofer IAPT has both robotic and CNC-based handling systems equipped with different powder nozzles to ensure application-specific alignment of the processes.

Laser and wire-based Directed Energy Deposition

DED based on laser and wire (DED-LB/w) is characterized by a very high degree of material utilization and low energy input.

 

The system design at the Fraunhofer IAPT with coaxial wire feed enables direction-independent material application and is therefore particularly geared towards additive manufacturing

Arc-based Directed Energy Deposition

DED-Arc is a process based on the combination of arc welding technology and robot-based or CNC-based handling. A variety of welding modes allows the process to be flexibly aligned. Thanks to the comparatively simple system design, DED-Arc can be a cost-effective alternative to other Additive Manufacturing processes.

Depending on the process type, Directed Energy Deposition (DED) differs in terms of the type of feedstock and energy source used. The material, either in powder or wire form, is fed into the process zone and melted by a laser or arc.

By layering multiple weld tracks, a 3D component is created. The process head is maneuvered using robotic systems or CNC machines.
