photoetched parts are generally made of brass and have a very high level of detail.They are created by a photochemical reaction and are often used to add details to plastic models.The biggest downside to photoetch parts is that because they are made similar to a photograph they are flat.In order to make a 3d shape you have to bend the parts.In most cases there are bend lines etched into the parts to make it easier to bend them and there are special tools that are helpful.They usually need to be painted, but some manufacturers offer prepainted photoetch parts. They are commonly used for instrument panels.The panel is made from the photoetch material and the dials for the instruments are printed on clear plastic.The clear plastic is glued to the back of the instrument panel to give a 3d effect.
