Laser Metal Deposition

Laser metal deposition (LMD) is an additive manufacturing process in which a laser beam forms a melt pool on a metallic substrate, into which powder is fed.

The powder melts to form a deposit that is fusion-bonded to the substrate. The required geometry is built up in this way, layer by layer. Both the laser and nozzle from which the powder is delivered are manipulated using a gantry system or robotic arm.

TWI has been developing LMD technology for the last ten years. For full details of our capabilities in this area, and to find out more about the process and the benefits it can bring to your business, visit the LMD page on our dedicated additive manufacturing website:

Examples of our work with Laser Metal Deposition

  • Repair of mould tool surfaces
  • Repair of high-value parts such as aeroengine components and military vehicles
  • Tipping of turbine blades with protective coatings
  • Surfacing of oil and gas drilling components
