Abstract
We propose a method to fabricate three-dimensional (3D) metallic movable microparts by the combination of two-photon microfabrication and electroless plating. In this method, polymeric movable microparts with anchors made by two-photon microfabrication are metalized by electroless plating, and then the anchors are removed by laser ablation using a femtosecond pulsed laser. As a result, a metalized freely movable micropart whose motion is restricted to a shaft can be produced. We succeeded in fabricating sophisticated 3D metallic microrotors by adjusting the experimental conditions of both electroless copper plating and laser ablation.
