Abstract: A method and apparatus for making a three-dimensional object including a large number of layers bonded together each having the contour of a thin slice of the object, are characterized in that each layer of the object is formed over its preceding layer by: applying a layer of a supporting material to the preceding layer; sculpture machining the supporting material layer according to the negative underface contour of the respective layer of the object to be formed; applying a layer of the object material in flowable form over the supporting material layer such that the underface of the object material layer takes the shape of the positive contour of the respective layer of the object to be formed; hardening the object material layer; and sculpture machining the upper face of the object material layer according to the positive upperface contour of the respective layer of the object to be formed.
