초록 ▼

A solid three-dimensional article is formed from a liquid medium by initially coating a layer of the liquid medium on a fixedly mounted apertured support plate. An initial cross-section or profile of the article then is formed by solidifying the liquid medium, or at least a portion thereof, on the support plate. In another embodiment, each layer of the liquid medium is formed by dispensing the entire layer from above the fixed support plate. In a further embodiment, a device is disclosed for dispensing a liquid medium in layers of uniform thickness on the medium surface of a laser modeling machine, for solidification when subjected to prescribed energy. The dispenser comprises an elongated applicator or coating bar of rectangular, essentially solid construction, with a liquid medium reservoir and dispensing passageways located adjacent a dispensing side of the bar. A feed tube and traversing mechanism support rods are secured to an opposite side of the bar. The dispensing passageways may be apertures arranged in multiple rows, with the apertures in at least one row offset with respect to the apertures in the other rows, for more uniform dispensing. In the alternative, the passageways may be inclined slots having portions overlapping in a direction extending longitudinally of the bar.

A method for forming a three-dimensional object from a medium capable of solidification when subjected to prescribed energy, comprising the steps of: providing a container for holding the medium; providing a support within the container for supporting the object being formed; forming a layer of medium above the support; solidifying a preselected cross-section of the layer by exposure to the prescribed energy according to the design for the object; relatively raising the medium surrounding the solidified cross-section thereby forming a meniscus around the periphery of the cross-section; forming a successive layer of medium above the solidified cross-section by filling the meniscus with medium from a coating means thereby breaking the meniscus such that the medium surrounding and above the solidified cross-section flow together; solidifying a preselected cross-section of the successive layer by exposure to the source of the prescribed energy according to the design of the object; and alternately repeating the successive layer-forming step and solidifying step to form the object.
