Photo etching tooling is digital, unlike costly conventional methods such as stamping. Moreover, tooling is generated within hours; whereas, hard tooling can take weeks.  A repeating pattern of a part's dimensions is created through CAD software. Then, a photoplotter machine produces two pieces of mylar film with the digital image. One piece is placed on top of the metal sheet and the other on the bottom. 

This low-cost process allows the engineer to generate a repeating pattern onto the tooling film to maximize the number of parts per sheet.  Digital tooling is easy to modify for prototype development and therefore significantly reduces project time. Part revisions are a snap which makes it ideal for prototypes or short runs. There is no wear on the tooling and it can be stored for the life of the part.
