Laser Metal Deposition, or LMD for short, has many benefits: it reduces waste, it is suitable for large components, it allows customization at a high level, and it can be used to manufacture as well as repair. This particular video was taken at 10,000 frames per second and the imaged area is 640×480 pixels.
TWI Ltd describes LMD as “an Additive Manufacturing (AM) process that uses a laser beam as an energy source, focused upon a substrate through a nozzle to create a melt pool. Material is then added to the melt pool as a powder or wire. The melted particles fuse and solidify while the nozzle is manipulated around the substrate to form a desired layer of the component. The nozzle’s path is determined by a CAD model, which is sliced into layers using specialist software. Layer by layer, a 3D part is created” (https://www.twi-global.com/what-we-do/research-and-technology/technologies/additive-manufacturing).
With our CAVILUX laser illumination technology including special bypass filters, you are able to see the LMD process without the bright laser light and have a clear view to the illuminated area allowing you to see all the details in it, from each individual powder particle from the nozzle to the 3D shape taking place.
