Five plus seven is? (answer as number)



Demands for longer life and higher efficiency results in higher wear and tear of components requiring better methods for repairing and re-manufacturing. The need for high performance components for sustainable operations, coupled with the ever increasing cost of materials, has intensified the search for re-manufacturing technologies that offer better quality and a near net shape finish. Some of the challenges for successful re-manufacturing are:

  • Part distortion

  • Large Heat Affected Zone (HAZ)
  • Integrity of repair


Direct Metal Deposition (DMD) is an advanced additive manufacturing technology that offers an excellent solution to the challenges above. DM3R uses the DMD process to repair and rebuild worn/damaged components that are hard to weld. This additive metal technology can also reconfigure parts to accommodate design changes which saves and reduces lead time.



  • Add metal on a 3D surface with a 5-axis motion system
  • DMDCAM software for precision & quick toolpathing

  • DM3R ranges from a few microns to several millimeters depth
  • Metallurgically bonded DM3R yields longer life to repaired part
  • Small heat affected zone (HAZ) (8-10 x shorter than PTA/TIG)
  • Part sizes can vary from a few centimeters to a few meters
  • Wide variety of material capability including steels, stainless steel, Stellite, Inconel, Titanium alloys, etc.
  • Deposit superior material so DM3R parts are often better than new parts


  • Turbine components, such as vanes, blades, knife edges, seals, etc.

  • Automotive components, such as engine heads, engine blocks, transmission parts, etc.
  • Wear components for agricultural, construction and heavy equipment industries

  • Oil and gas industry components

  • High value tools
