Electrochemical fabrication methods including use of surface treatments to reduce overplating and/or planarization during formation of multi-layer three-dimensional structures

This invention describes a way to build complex 3D objects by stacking many thin layers. Each layer involves creating a pattern with a conductive metal, then treating its surface to prevent other materials from sticking where they shouldn't, or to make them easier to clean off. The initial claims specifically detail using electroplating with a mask to form the patterned metal layers.
