Laser rapid manufacturing
From Wikipedia, the free encyclopedia
Laser Rapid Manufacturing (LRM) is one of the advanced additive manufacturing processes that is capable of fabricating engineering components directly from a solid model.
In this technique, a solid model of the component to be fabricated is made either by 3D imaging system or by designer using computer-aided design (CAD) software or by math data as an output of numerical analysis. Thus obtained model is sliced into thin layers along the vertical axis. The thin layers are converted into corresponding numerical controlled (NC) code and are sent to LRM station in suitable format (e.g. G&M code). LRM station employs a laser beam as a heat source to melt a thin layer on the surface of the substrate/deposited material and fed material to deposit a new layer as per shape and dimensions defined in NC code. A number of such layers deposited one over another and it results in three-dimensional (3D) components directly from the solid model.
