In contrast to chemical etching and laser cutting, electroforming is an additive process. Electroformed stencils are "grown" by electro-depositing a plating material, usually nickel, onto a mandrel carrying a negative, photo-resist image of the aperture pattern. The process produces extremely precise, smooth-walled apertures with a natural taper that require no additional finishing processes.
