Photochemical machining, also known as photochemical etching or chemical milling, is a subtractive manufacturing process that uses photoresists and etchants to remove unwanted material to produce a highly precise metal component. Ideally, this process is used when working with thin materials that have complex geometry and dense design features, without inducing thermal stress and distortion into the component that typically takes place when using traditional manufacturing methods.
