    Abstract: The present invention relates to a system and a method for optimizing printing parameters, such as slicing parameters and tool path instructions, for additive manufacturing. The present invention comprises a property analysis module that predicts and analyses properties of a filament object model, representing a constructed 3D object. The filament object model is generated based on the tool path instructions and user specified object properties. Analysis includes comparing the predicted filament object model properties with the user specified property requirements; and further modifying the printing parameters in order to meet the user specified property requirements.

    Abstract: The present disclosure provides methods and systems for fabricating at least a portion of a three-dimensional (3D) object. In an example, at least one feedstock may be directed from a source of the at least one feedstock towards a base. The at least one feedstock may comprise a polymeric material and a cross-linking agent. The cross-linking agent may be in an inactive state. Next, first layer of the at least one feedstock may be deposited adjacent to a second layer previously deposited adjacent to the base. The first layer may correspond to at least a portion of the 3D object. During or subsequent to deposition adjacent to the second layer, the cross-linking agent in the first layer may be in an active state to induce cross-linking between the polymeric material in the first layer and a polymeric material in the second layer.

    Abstract: A consumable scaffold and technique for supporting an object while it is being manufactured is disclosed. The consumable scaffold comprises a base sheet and an array of pillars that are cantilevered from one side of the sheet. The consumable scaffold resembles a bed of nails. Each pillar in the array of pillars is trimmed to a desired length and the object is manufactured by fusing thermoplastic filaments to the tips of the pillars.

    Abstract: A technique for additive manufacturing that avoids the necessity of having a build plate. The illustrative embodiment comprises two anchor plates from which a structure is constructed that forms at least the initial support for the object to be manufactured. The envelope of the structure can be a cylinder, a box, an n-sided prism, a hyperboloid of one sheet, a cone, the frustum of a cone, a pyramid, and the frustum of a pyramid.

    Abstract: Methods for producing 3D printing composite polymer materials for use in additive manufacturing processes are provided. The methods result in enhancing the material properties of the printing material by providing a uniform and smooth surface finish of the printing material and the nozzle extrudate for additive manufacturing processes, such as Fused Filament Fabrication. The method includes implementing impregnation techniques for combining carbon nanotubes or other nano-fillers, a polymer resin and a fiber material to produce a polymer material that can be processed into a printing material. Further, the method may include combining the carbon nanotubes or other nano-fillers and the polymer resin to form a masterbatch that may be further combined with the fiber material through an extrusion process. The method results in a printing material with enhanced material properties and smooth surface finish for the printing material and resulting nozzle extrudate for Fused Filament Fabrication.
