Process Overview

Directed Energy Deposition is the process of a jetting powdered material into a melt pool.  This melt pool is created by an energy source, typically a laser, which is attached to a machine tool arm.  In this way, the machine tool can build a part up layer-by-layer, or simply build upon an existing part to create new structures or repair damaged ones.  Material is added to the locally molten part in a continual process, like how FDM uses a print head to deposit thermoplastic. This process family is typically used for extremely large prints.  Not typically known for its accuracy so much as its speed and ability to build upon existing structures, DED systems are sometimes coupled with CNC machine tools in the same manufacturing cell to create higher tolerance parts.

Advantages

  • Strong, End Use Parts - State of the art technology prints durable metal parts
  • Metal Repair - DED printers can print metal onto existing parts in need of repair
  • Build Volume - Some DED printers can build parts several feet in each direction 
  • Intricate Geometry - 5-axis DED models can produce complicated geometries without support

Limitations

  • Surface Finish - Surface finish exceeding 1000 µin Ra requires post-processing to achieve the required smoothness for many applications 
  • Relaxed Tolerance - DED machines can typically achieve a finest tolerance of 0.01” (0.25 mm), making small features difficult
