ABSTRACT:
A rapid prototyping system forms three-dimensional objects by depositing layers of material on a substrate. A planer stator containing a grid of stator elements is positioned above and generally parallel to the substrate. An extrusion head is magnetically suspended below the stator and is separated from the stator by an air bearing. An electromagnetic drive receives control signals from moving the extrusion head relative to the grid of stator elements. An umbilical provides mechanical damping to the head to reduce resonance of the head during movements.
