Laser Deposition Technology (LDT)

Laser Deposition Technology (LDT) is a process in which metal powder is injected into the focused beam of a high-power laser under tightly controlled atmospheric conditions. The resulting deposits may then be used to build or repair metal parts for a variety of different applications.
Laser Deposition Technology (LDT) is a blanket name that encompasses many "like" processes-direct metal deposition (DMD), laser metal deposition, laser additive manufacturing (LAM), and others-that use a focused laser beam as the heat source for depositing powdered metals.
The key benefits of this process over traditional repair techniques are: 1) metallurgical bond versus a mechanical bond, 2) relatively low heat input, 3) minimal stress and distortion created by deposits, and 4) rapid cooling rates.
Sample applications include shaft repair, aerospace parts, bearing housings, compressor seals, and custom free form manufactured parts.
Laser repairs can be made with, but are not limited to, the following alloys: nickel, cobalt, Iconel®, titanium, stainless steel (420, 316, 304), and hardfacing alloys.
