    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: 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.

    Abstract: A system and method for additive manufacturing of otherwise thermosetting polymers, such as PAI, is disclosed. The system includes fast-curing hardware that facilitates curing each deposited layer before a successive layer is deposited. This reduces the time to provide a finished part from weeks to hours.

    Abstract: An apparatus performing as a base for printing 3D objects using high temperature thermoplastics employing additive manufacturing methods is provided. The apparatus comprises a heated build platform, a thin removable plate secured on top of the build platform, a high temperature polymer coating applied over the removable plate, and surface treatment of high temperature polymer coating to maintain adhesion between 3D object and printing surface. Also, the removable plate has low coefficient of thermal expansion compared to build platform below it, for avoiding bowing of the plate as it is heated due to heated build platform, hence providing flat printing surface. The thin removable plate allows 3D objects to pop off the plate upon cooling, without damaging the polymer coating, the plate, or the object. It also allows for continuous operation of printing, while the plate is released for cooling, a new plate is installed for printing.
