Abstract
An FDM printer that provides five degree-of-freedom printing capabilities. In one embodiment, the FDM printer includes three transitional drive devices that allow a printer print head to be translationally moved in the X, Y and Z axes planes and a pair of rotationally drive devices that allow a workpiece platform to be rotated in the Y-axis plane and the combined X-axis and Z-axis planes. In this manner, the relative position between the print head and the workpiece platform allows the printer to print complex workpieces in a single continuous print, such as workpieces including large closed, hollow geometries, and without the need for providing support structures for overhangs and the like.
