Near net shape

Near-net-shape is an industrial manufacturing technique. As the name implies, the initial production of the item is very close to the final, or net, shape.^[1] This reduces the need for surface finishing. By minimizing the use of finishing methods like machining or grinding, near-net-shape production eliminates more than two-thirds of the production costs in some industries.
