Powder metal repair process

In the DMLD process, a laser beam is used to form 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. Both the laser and nozzle from which the powder is delivered are manipulated using a CNC robot or gantry system.

The process is also known as laser cladding, laser deposition, laser engineering net shape (LENS) and laser additive manufacture (LAM).
