Directed Energy Deposition 3D Printing Service

3Diligent's directed energy deposition 3D printing service is capable of delivering repairs on parts or ground-up fabrication of geometries—especially parts larger than one cubic foot. If you think DED printing might be optimal for your project, submit an RFQ in our secure portal or email us to discuss your project needs.

Directed Energy Deposition 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, similar to the way an FDM uses a print head to deposit thermoplastic. This process family is typically used for extremely large prints. Not known for its accuracy so much as its speed and ability to build upon existing structures, Directed Energy Deposition 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. Directed Energy Deposition 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. Directed Energy Deposition machines can typically achieve a finest tolerance of 0.01” (0.25 mm), making small features difficult.
