Abstract: A three-dimensional dental device is fabricated in a layer-by-layer approach using a support material. The support material is deposited in a liquid form on a surface, hardened by cooling or ultraviolet (UV) curing, and selectively ablated to create an area within which the desired structure of the dental device will be formed. Active dental material is deposited into this area, and the layer-by-layer process repeated until the three-dimensional dental device has been completed. Thereafter, any remaining support material is removed by water or other solvent.
