A variety of support structures and build styles for use in Rapid Prototyping and Manufacturing systems are described wherein particular emphasis is given to Thermal Stereolithography, Fused Deposition Modeling, and Selective Deposition Modeling systems, and wherein a 3D modeling system is presented which uses multijet dispensing and a single material for both object and support formation.

Selective deposition modeling method and apparatus for forming three-dimensional objects and supports

A method of manipulating data in a method for forming a three-dimensional object layer by layer from an ink jettable, solidifiable material by providing data corresponding to a plurality of polygons defining the outer surfaces of a plurality of three-demiensional objects and providing sets of x, y, and z coordinates corresponding to each layer and identifying x and y coordinates with each z coordinate such that directional values and counter values are determined for each y coordinate in a first set of coordinates generated. A second set of y coordinates are generated according to a formula that permits the determined layers to be processed to form a three-dimensional object.

Method and apparatus for data manipulation and system control in a selective deposition modeling system

A system and associated method for forming three-dimensional objects under computer control and from a material which may be rendered flowable and then dispensed on a layer-by-layer basis. The layers of the material solidify or otherwise physically transform upon being dispensed thereby forming successive cross-sections. The dispensing process is repeated whereby successive layers adhere to each other thereby forming the object.

Selective deposition modeling system and method

Embodiments of the instant invention are directed to various methods and an apparatus for building a three-dimensional object represented by object data and support data using thermal stereolithography. Some preferred embodiments of the building techniques include multiple building materials, wherein, in some preferred embodiments, a different building material is used to build the object and the support. Embodiments of the methods for building three-dimensional objects include manipulation of the data, which is represented by a plurality of start/stop transitions to facilitate the computation of Boolean operations. In preferred embodiments, the object is built by selective disposition of the building materials in accordance with the object and support data.

Rapid prototyping system and method with support region data processing

Methods and apparatus for use in building three-dimensional objects on substantially a cross-sectional basis including methods and apparatus for forming successive layers using counter-rotating rollers, ink jet recoaters, spinning members which sling material, applicator bars that dispense material via a meniscus and/or independently dispensed streams, and also including methods and apparatus to determine a preferred region over which to form a layer and to check for building errors.

Rapid recoating of three-dimensional objects formed on a cross-sectional

A semi-insulating coating or surface layer is applied over insulating materials such as a circuit board or wiring harness or feedthrough insulator. The paint is electrically fixed to ground and as a result leaks away charge buildup before large pulse discharges occur. For example, pure tin oxide particles in phenoxy resin binder forms a paintable application for the invention.
