I have recently seen an industrial process that people weld (similar to brazing) many small pieces of copper wire on the curvature surface (copper) such as vase, to develop an artwork (art piece). I thought that it can be produced much faster and more accurately with the photolithography process we use in PCB, Wafer Fab, LCD, etc. with plating or etching. However, our applications are targeted mainly for planar surface! Do any of you out there know some photolithography process or equipment which is to transfer arkwork on to a curvature surface? Any idea or information you can help me? Thank you in advance! Richard J.
