Zusammenfassung:	A method of manufacturing a three-dimensional object facilitates the removal of support material from the object. The object and support are moved to a position opposite a microwave radiator and the microwave radiator is operated change the phase of a supporting material from solid to liquid. A controller either monitors the expiration of a predetermined time period or a temperature of the object to determine when the microwave radiator operation is terminated. Because the dielectric consumption factor of the supporting material is higher than that of the object, the microwave radiation does not damage the object. 种制造三维物体的方法，其便于从物体去除支承材料。该方法包括使物体运动至与微波辐射器相对的位置，以及操作微波辐射器以使支承材料从固体相变成液体。控制器监控预定时间段的届满或监控物体的温度，以确定何时终止微波辐射器操作。由于支承材料具有大于物体的介电损耗因子的介电损耗因子，因此微波辐射不损坏物体。
