Laser Additive Manufacturing

Rapid prototyping is used in applications where design prototypes or a low volume of complex parts are required to be fabricated quickly. The process enables manufacturing of complex parts out of either an epoxy polymer or powder without the need of complex tooling. The process is differentiated between Stereolithography (SLA) and Selective Laser Sintering (SLM). In both the SLA and SLM processes, a 3-D CAD model is sliced into many layers like a stack of cards then transferred to the SLA or SLM tool. The laser beam is steered by a galvanometric scanner head and builds up the part layer by layer. After each layer is processed, a layer of polymer or powder is deposited on top of the part and the next laser processing step begins.
