The 3D micro-mold which is fabricated by the femtosecond laser cutting and micro electric resistance slip welding is formed through the lamination of multilayer 2D microstructures. By using this technology, the 3D micro-mold with a high depth-width ratio can be manufactured. In order to improve the laminated precision and joining strength of each layer of 2D microstructure, this research applied layer-by-layer...
