Abstract: A water dispersible sulfopolymer for use as a material in the layer-wise additive manufacture of a 3D part made of a non water dispersible polymer wherein the water dispersible polymer is a reaction product of a metal sulfo monomer, the water dispersible sulfo- polymer being dispersible in water resulting in separation of the water dispersible polymer from the 3D part made of the non water dispersible polymer.

Abstract: A method for printing a three-dimensional part (30) with an additive manufacturing system (10), which includes providing a part material that compositionally has one or more semi-crystalline polymers and one or more secondary materials that are configured to retard crystallization of the one or more semi-crystalline polymers, where the one or more secondary materials are substantially miscible with the one or more semi- crystalline polymers. The method also includes melting the part material in the additive manufacturing system (10), forming at least a portion of a layer of the three-dimensional part (30) from the melted part material in a build environment (12), and maintaining the build environment (12) at an annealing temperature that is between a glass transition temperature of the part material and a cold crystallization temperature of the part material.

Abstract: A method of forming a three-dimensional object using an extrusion- based layered deposition system, the method comprising generating a build path (10) for building a layer of the three-dimensional object, where the build path (10) defines a void region (20). The method further comprising generating at least one intermediate path in the void region (20), and generating a remnant path (21) based at least in part on the at least one intermediate path.

Abstract: The present invention is a method (10) for manufacturing a three-dimensional object. The method (10) includes receiving (14) digital information of the three-dimensional object over a communication line and building (30) the three-dimensional object based at least in part on the received digital information, where at least part of the three-dimensional object is built by rapid manufacturing, and where the three-dimensional object comprises an exterior surface. The method also includes vapor smoothing (32) at least a portion of the exterior surface of the three-dimensional object.
