Abstract
A positioning mechanism for precisely moving a 3D printing stage in two dimensions is disclosed. The positioning mechanism consists of a first drive assembly, a second drive assembly, a moveable platform, and a stationary frame. The first and second drive assemblies each consist of a gear rack, pinion wire, and actuator. The first and second drive assemblies are configured to move the stage in orthogonal directions in a substantially horizontal plane. Both the first and second pinion wires are in direct contact with the stage as well as the frame, thereby providing an effective parallel linkage between stage and frame.
