Abstract
A system and method for producing a three-dimensional object (10, 70) from coordinates generated on a computer machine (12) is disclosed wherein the object has improved dimensional accuracy. Control signals (20b) are generated for controlling a servo (20) that controls a reaction or interaction of material (20a) at the coordinate points to form the object while a second servo (22) serves to build up a three-dimensional support system (42) in response to support control signals (22b). Support control signals (22b) are generated at the same time the coordinate points of the design are generated to specify strategic points of the object at which a support environment need be placed in order to insure the dimensional accuracy of the object avoiding warpage or other dimensional distortion. As a support environment, a series of webs (50, 52, 54) or columns (76), or encapsulation (44, 92) may be provided for providing a support environment for the object.
