摘要： A three-dimensional object is made by repeating a process. An optical beam is irradiated on a predetermined portion of a powdery layer to form a sintered layer. A new powdery layer is formed on a surface of the sintered layer. An optical beam is irradiated on a predetermined portion of the new powdery layer to form a new sintered layer united with the underlying sintered layer. Because a portion of the sintered layer that is higher than a predetermined level is removed as occasion demands, the abnormally sintered portion on the sintered layer can be removed, making it possible to prevent stoppage of the shaping process, which may be caused by the abnormally sintered portion.

摘要： A three-dimensional object is fabricated from a light curable liquid resin by repeating the following process to superimpose a plurality of cured resin layers. The process utilizes a vessel containing a volume of the liquid resin and a vertically movable platform. In the process, the platform is immersed in the liquid resin in the vessel to dispose an overlay surface of an immediately previously cured layer sufficiently below the liquid level of the liquid resin. The platform is then raised such that the overlay surface is slightly higher than the liquid level of the liquid resin in the vessel, while keeping the liquid resin on the overlay surface connected with the surrounding liquid resin in the vessel by the effect of surface tension acting on the liquid resin. An excess amount of the liquid resin on the overlay surface is removed to form a liquid resin layer having a desired thickness. The platform is lowered such that an upper surface of the liquid resin layer is substantially in flush with the surrounding liquid level in the vessel, while keeping the desired thickness of the liquid resin layer. A light is then radiated to the liquid resin layer so as to cure it into the cured resin layer.

摘要： A process of fabricating a three-dimensional object from a light curable liquid resin includes irradiating a light to a surface of the light curable liquid resin so as to form successive cross-sectional layers of the cured resin at that surface and to superimpose the successive layers on each other. An improvement resides in that one or more of the successive layers is made to have different portions made through different curing conditions. By providing such cross-sectional layers having different curing conditions, the resulting three-dimensional object can be made into accurate outer configuration without leaving any critical residual stress therein.
