Photo etching, chemical etching, chemical milling.
Use photo etching to create deep marks in a huge range of metals. Artwork can be etched from one or both sides and can also include full cut outs and voids in the finished sheets.
The process relies on photo tooling to transfer your artwork via an outputted film to your chosen metal that is coated with a photosensitive resist layer. When the film has been lined up an exposure unit then exposes the image so that any areas not covered by the film remain soft. These soft areas are then washed away leaving areas of the metal exposed. The sheet is then passed through an etching solution that eats away the exposed areas. After the etching solution has done its job the sheet is stripped of the remaining photoresist leaving your finished item/s.
Photoetching can achieve some very high detailed components. it is also possible to leave items ‘tabbed’ into thin sheets for removal at a later date. Another popular choice is to infill the etched areas with colour to produce a contrast effect with the surrounding material.
