Direct metal deposition (DMD) Heat is generated using a focused heat source of various kinds, sufficient to melt the surface of the substrate and form a small melt pool. Material is added to the melt pool using a focused powder stream or a wire feed system to form a raised portion of material. To create the desired geometry, the substrate is ...
Metal deposition describes any additive manufacturing method where a metal is layered onto some other material such as metals, ceramics, and even plastics. How the metal is deposited onto the substrate can vary greatly. Today, we will take a look at a few different types of metal deposition – and, of course, why we think cold spray ...
The most promising technology of product manufacturing is direct laser deposition analogue direct metal deposition (DMD), when the product is formed from a powder, which is supplied by compressed gas-powder jet directly into the laser action zone [ 8, 9, 10, 11 ].
An additive manufacturing (AM) machine using laser metal deposition (LMD) melts metal powder in a continuous stream to build up a part. The process looks similar to welding, but that impression is misleading. The similarity suggests a somewhat primitive process, one not capable of fine detail or intricate geometries.
Metal additive manufacturing is taking more and more space in the industry. From aeronautics to medical applications, these 3D printing technologies are offering brand new opportunities. Here, we will talk about Direct Metal Deposition, an additive manufacturing technology using a laser to melt the metallic powder.
Even finding consensus on a name for the laser direct metal deposition (laser cladding, direct metal deposition, direct laser deposition, directed light fabrication, laser powder fusion, laser engineered net shaping, etc) process has to-date proved impossible.
The laser metal deposition (LMD) process is a direct energy deposition process. Laser metal deposition is an additive manufacturing process where a laser beam is used to form a melt pool on the surface of a metal object. Metal powder is then injected using a gas stream. A thin layer of the base material is melted by the laser heat source in a ...

The process of direct laser deposition or laser cladding allows, through the fusion of a filler material, usually in the form of metal powder, on the surface of a material and, by the action of a laser beam, the generation of a coating with similar or improved properties than those of the base substrate. The advantages of this method include ...
Laser direct metal deposition: theory and applications in manufacturing and maintenance A.J. Pinkerton, in Advances in Laser Materials Processing, 2010 16.6 Conclusions Laser direct metal deposition is an extremely flexible technique with application in multiple areas from large scale component repair to medical implant manufacture.
Laser metal deposition or LMD refers to the process of forming a pool of melted metal on a metallic substrate with the help of a laser. A gas stream is used for injecting metal powder into the substrate. This absorbed metal powder forms a metal deposit on the substrate of the metal.
