    摘要： Systems and methods for producing three-dimensional objects are provided. One exemplary system, among others, includes a layer forming system. The layer forming system is operative to implement criteria for forming the three-dimensional object. The three-dimensional object includes a plurality of layers and each layer includes layers selected from a shell layer and an interior layer. The shell layer includes at least one shell voxel, and the interior layer includes at least one interior voxel. In addition, the layer forming system is operative to form the layers in an iterative manner according to the criteria, plane at least one layer in a manner according to the criteria, control waste produced by controlling the formation of the layers using the criteria provided, and form the object.

    摘要： The present invention is drawn to solid freeform fabrication systems and methods for producing three-dimensional objects. The system can include build material configured to be deposited in layers to form a three-dimensional object; and support material configured to be deposited adjacent to the build material for supporting the build material during formation of the three-dimensional object. The support material can also be configured to form a feature that imparts a predetermined property within the three-dimensional object.

    摘要： The present invention is drawn to a solid freeform fabrication system for producing a three-dimensional object. The system can include a dispensing system and a curing system. The dispensing system can be adapted to separately dispense build material and support material, wherein the build material and the support material are adapted to contact one another at an interface after being dispensed. The curing system can be adapted to harden the build material after being dispensed but before the support material is dispensed, wherein mixing between the build material and the support material is inhibited at the interface.

    摘要： A method of dispensing a single ligament of fluid includes ejecting a first quantity of fluid from an inkjet dispenser toward a substrate, and ejecting a second quantity of fluid from the inkjet dispenser toward the substrate, wherein the second quantity of fluid is ejected from the inkjet dispenser at a frequency sufficient that the second quantity of fluid catches the first quantity of fluid thereby forming a single ligament of fluid prior to contacting the substrate.
