Maximum Speed in Three Dimensions

The 3DMD process used by Ponticon was initially developed at the Fraunhofer Institute for Laser Technology ILT and the RWTH Aachen University Chair Digital Additive Production DAP. Based on the further development carried out by Ponticon the advantages of this technology can be used for the first time for additive manufacturing, coating and repair of components of any geometry as well as the development of novel alloy systems.

Because rotationally symmetric bodies can be accelerated to required feed rates with relatively little effort, the application of high-speed DED technology has been limited so far. The pE3D system of Ponticon, designed for maximum stiffness and dynamics, is the first to achieve the feed rates required for the 3DMD process in all three spatial directions. Therefore, components with free-form and plain surfaces may now be additively manufactured, coated and repaired utilizing a diverse material portfolio.

Process principle

3DMD Dynamic Material Deposition

The designation of the process originates from the high speeds at which the nozzle used for powder feed moves relative to the workpiece. Contrary to the conventional method of laser-based Directed Energy Deposition, the metal powder is already molten above the surface of the workpiece. At the same time, a defined proportion of the laser beam creates a homogeneous melting zone on the surface of the workpiece. Hence, the penetration depth of the heat-affected zone is limited to only a few micrometers. The melted powder hits the surface of the workpiece and metallurgically bonds to its base material.
