For some people, the expression spot size of a laser beam means its smallest diameter at the focal plane when focused by a lens, whereas for other people they mean the laser beam's diameter when it exits the laser, or at any other place where they need to measure it. It is important to make a distinction between the two cases because the approach to measurement is different. When a laser. Laser Beam Melting is one possible Additive Manufacturing process which allows the production of metal components with very good mechanical properties suitable for industrial applications.

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. For weldinf purposes, laser beam is coherent, monochromatic light in the infrared or ultraviolet frequency portion of the electromagnetic radiation spectrum. Therefore, the beam is invisible Laser beam melting is a generative manufacturing process which serves for the tool-free production of metallic components with special geometric features. With local melting of the metal powder by a laser beam and the subsequent solidification of the material, the component can be built up in layers Applying additive manufacturing technologies in the tooling sector is reaching a new level with Laser Beam Melting, since this technology allows layer-by-layer manufacturing of completely dense tool and die inserts in standard high-alloyed tool steel.
