5. 8,512,024    
Multi-extruder 

There is a need for a three-dimensional fabrication device that extrudes multiple build materials.

Pax of MakerBot Industries, Brooklyn, New York, developed multiple extrusion drive motors are nested in an overlapping configuration that permits re-use of the drive axes to support drive gears and complementary guide bearings, resulting in a compact arrangement of independently controllable extruders for multiple build materials.

Process of making a three-dimensional object 

Ito and Hagiwara of CMET Inc., Japan, developed an optical three-dimensional shaped item with smooth surfaces.  A three-dimensional shaped item consists of  superimposed one upon another, multiple cured resin layers having a given configurational pattern formed by irradiating with actinic energy rays a molding face consisting of an actinic energy ray curable resin composition.  The surface unevenness is smoothed by segregation of a component in the material.  This component may be an unreacted acrylic, epoxy, hindered phenol or ester compound.

Automated 3D build processes 
 
Pax, Smith and Mayer of MakerBot Industries, New York, developed a conveyor to support multiple, sequential builds from a three-dimensional fabrication machine.  The conveyor may be heated/cooled, coated, or otherwise treated to assist in adhesion during a build, as well as removal of objects after a build.  Each fabricated object may be automatically removed from the conveyor as the conveyor moves in order to restore a buildable surface for fabrication of additional objects.  (RDC 10/31/2012)

Method and apparatus for rapidly generating aerospace tools
 
Dietrich, Macke, Jr. and Washington of Boeing, Illinois, developed a method and apparatus may for manufacturing tooling on the spot as needed. A shell may be formed having a support structure located in a cavity in which the shell and the support structure may be formed using an additive manufacturing system from a design of a tool. The cavity of the shell may be filled with a filler material through an opening in the shell. The shell may be cured with the filler material to form the tool. (RDC 5/24/2012)
