A method for chemically milling sheet metal to form three-dimensional objects comprising masking the sheet metal by selectively applying a resist material to opposite sides of the sheet metal to form a design, applying an etchant to the masked metal which erodes the metal according to the design, and simultaneously forming connecting tabs and score lines. The tabs and score lines allow certain design portions to be bent to different planes to form the three-dimensional object.
