Center for Innovative Materials Processing through Direct Digital Deposition
Large-Scale Robotic AM System
Manufacturer: Penn State ARL
System Type: Directed Energy Deposition System
Description: Custom-configured and designed, this DED system features the most advanced, state-of-the-art capabilities for high-deposition rate additive manufacturing. A six degree-of-freedom articulated robot and two-axis rotary positioner synchronously locate the processing head and workpiece for deposition. The system can accommodate large structures fitting within a 2m x 3m x 3.5m envelope and can also produce a wide variety of complex geometries given the robotic configuration’s positioning flexibility.
Up to 12 kW of laser power is directed through a water-cooled two-axis beam scanning process head for programmable energy distribution. Wire or powder feedstock can be used for fabrication with deposition rates in excess of 10 kg/hr. The integrated wire-based system includes hot-wire capabilities for wire pre-heating. By combining the most advanced processing capabilities into one integrated platform, this system represents the next generation of large, rapid additive manufacturing.
