Directed Energy Deposition (DED) metal additive manufacturing is a versatile process that can be used for a variety of applications, including repair and cladding. In repair applications, DED is used to restore worn or damaged surfaces to their original dimensions and functionality. In cladding applications, DED is used to deposit a layer of dissimilar material onto a substrate to improve its properties, such as wear resistance, corrosion resistance, or thermal conductivity.
DM3D offers industry-leading Directed Energy Deposition (DED) technology for metal cladding and repair applications. Our innovative DED process utilizes a high-powered laser to melt and deposit metal powder and wire, enabling the restoration and enhancement of critical components.

Our Repair and Cladding Services:

• Component Repair: We can repair cracks, defects, and other imperfections in metal components, extending their service life and reducing the need for replacement.
• Dimensional Restoration: We can restore the original dimensions of worn or undersized components, ensuring proper fit and function.
• Surface Cladding: We can clad metal surfaces with wear-resistant, corrosion-resistant, or other specialty alloys to enhance performance and service life

DED – Highest value technology for repair and cladding applications for several reasons:

• High Precision: DED is used to deposit material with very high precision, which is essential for restoring complex geometries or creating thin, uniform clads.
• Material Versatility: DED is used with a wide variety of metal powders, including steels, nickel alloys, titanium alloys, and aluminum alloys. This allows for the selection of a material that is precisely matched to the requirements of the repair or cladding application.
• Minimal Heat Input: DED uses a focused energy beam to melt the metal powder, which minimizes heat input to the substrate. This helps to minimize distortion and warping, which is important for maintaining the dimensional accuracy of the repaired or clad part.
• Strong Bonds: DED produces strong metallurgical bonds between the deposited material and the substrate. This ensures that the repair or clad layer will be durable and long-lasting.

DED Repair Applications

DED can be used for a variety of repair applications, including but not limited to:

• Shaft repair: DED can be used to repair worn or damaged shafts, such as those used in pumps, turbines, and gearboxes.
• Pump and valve repair: DED can be used to repair damaged impellers, housings, and valve bodies.
• Mold and die repair: DED can be used to repair damaged molds and dies, which can save time and money compared to replacing the entire mold or die.
• Aerospace component repair: DED can be used to repair cracks, corrosion damage, and other defects in aerospace components.

DED Cladding Applications

DED can be used for a variety of cladding applications, including but not limited to:

• Wear resistance cladding: DED can be used to deposit  wear-resistant material onto a substrate to improve its wear life. This can be used to extend the service life of components that are subjected to wear and tear, such as bearings, gears, and cutting tools.
• Corrosion resistance cladding: DED can be used to deposit a corrosion-resistant material onto a substrate to protect it from corrosion. This can be used to protect components that are exposed to corrosive environments, such as chemical processing equipment and marine structures.
• Thermal conductivity cladding: DED can be used to deposit a material with high thermal conductivity onto a substrate to improve its heat transfer capabilities. This can be used to improve the performance of heat exchangers, heat sinks, and other thermal management components.
