Multi-Scale 3D Printed Capillary Gripper

Ahstract- This paper presents a capillary gripper able to pick and place sub-millimetric 1005 SMD components. It is manufactured by combining stereolithography for millimetric parts and two-photon lithography for smaller details. It is found that the similarity of resists used for both printers allows a good adherence between components. This combination allows innovative technical solutions for the capillary gripper design, such as a series of pillars of different lengths providing a novel release mechanism.
