초록 ▼

A process of fabricating a three-dimensional object from a light curable liquid resin by radiating a light to a surface of the liquid resin to form successive cross-sectional layers of the cured resin superimposed on each other. The process makes it possible to rapidly form on a platform or on a previously cured layer a fresh stratum of a desired thickness to be subsequently cured into the corresponding layer. The process utilizes a vessel containing a volume of the liquid resin and a platform carrying the layers, and comprises the steps of a) forming the stratum of the liquid resin on an overlay surface of the platform or previously cured layer outside of the liquid resin in the vessel; b) immersing the resulting stratum into the liquid resin in the vessel to place a top surface of the stratum approximately in level with a liquid level of the vessel, thereby surrounding a periphery of the stratum by the liquid resin in the vessel; c) allowing a portion of the liquid resin surrounding the stratum to flow toward the periphery of the stratum such that the stratum has a continuous flush top surface over substantially the entire of the overlay surface; and d) radiating the light to the stratum so as to cure it into the cross sectional cured layer. At the step c), only a minimum amount of the resin is caused to flow into the stratum from the surrounding resin and therefore expedite to the formation of the stratum into a straight configuration.

In a process of fabricating a three-dimensional object from a light curable liquid resin of viscous nature by radiating a light to a surface of said light curable liquid resin to have successive cross-sectional layers of the cured resin and superimposing said layers on each other, said process utilizing a vessel containing a volume of said light curable liquid resin and a platform capable of moving in and out of said liquid resin within said vessel for carrying thereon a stratum of said liquid resin which is to be subsequently cured by exposure to the radiation of said light into said cross-sectional cured layer, said platform or previously cured layer defining thereon an overlay surface with respect to the next superimposed cured layer, an improvement comprising the following steps of: a) forming said stratum of said liquid resin on said overlay surface of said platform or previously cured layer outside of said liquid resin within said vessel, the resulting stratum having a rounded periphery; b) immersing the resulting stratum into said liquid resin in said vessel to place a top surface of said stratum approximately in level with a liquid level within said vessel, thereby surrounding said rounded periphery of said stratum by the liquid resin in said vessel; c) allowing a portion of said liquid resin in the vicinity of said rounded periphery of said stratum to flow toward said rounded periphery in such a manner as to eliminate the rounded periphery and to give a continuous flush top surface to said stratum with a desired thickness extending over substantially the entire of said overlay surface; and d) radiating said light to said stratum so as to cure it into said cross sectional layer of the cured resin.
