Abstract

This paper proposes a 3D-printed micro-positioner actuated by piezoelectric elements. The lever-based amplifying mechanism and flexure hinge mechanisms are fabricated by a commercial 3D printer. Large step response, step-train response and sinusoidal response are presented to show the performance of the proposed system. Experimental results demonstrate 100 micrometer stroke with 1 micrometer resolution. Moreover, this micro-positioner is capable of tracking sinusoidal motion. Using 3D-printing technique, micro-positioners can be further optimized iteratively and cost-effectively.
