Laser engineered net shaping (LENS) is an additive manufacturing technique for rapidly fabricating, enhancing and repairing metal components directly from CAD data. The processes use a high power solid state laser focused onto a metal substrate to create a ~1 mm diameter melt pool.
LENS is a technique that uses a powerful laser to shape and repair metal parts directly from computer-aided design (CAD) files. The process involves focusing a high-powered laser beam onto a metal substrate to create a small molten pool of metal.
