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.

Method and a system to optimize printing parameters in additive manufacturing process

The present invention provides a system and a method for real time monitoring and identifying defects occurring in a three dimensional object build via an additive manufacturing process. Further, the present invention provides in-situ correction of such defects by a plurality of functional tool heads possessing freedom of motion in arbitrary planes and approach, where the functional tool heads are automatically and independently controlled based on a feedback analysis from the printing process, implementing analyzing techniques. Furthermore, the present invention provides a mechanism for analyzing defected data collected from detection devices and correcting tool path instructions and object model in-situ during construction of a 3D object. A build report is also generated that displays, in 3D space, the structural geometry and inherent properties of a final build object along with the features of corrected and uncorrected defects. Advantageously, the build report helps in improving 3D printing process for subsequent objects.

Method to monitor additive manufacturing process for detection and in-situ correction of defects

An article of manufacture is disclosed that is formed by jointly controlling a printhead and a worktable to provide three dimensional printing and insuring every point in a three dimensional print volume can be reached. Similarly, systems and methods are described to extend robot reach by coordinating robot and worktable control.

Methods and apparatus for controlling motion of an articulated robot

Methods and systems are disclosed for structurally analyzing and/or three-dimensional printing a part. The method may comprise receiving a model of the part for three-dimensional printing from a material comprising a matrix, receiving one or more properties for the material, and using the model, determining a print head tool path for use during the three-dimensional printing of the part. The method may also comprise determining a trajectory of at least one stiffness-contributing portion of the material based at least in part on the print head tool path, determining a performance of the part based at least in part on the one or more properties and the trajectory, and electronically outputting the performance of the part.

Systems and methods for structurally analyzing and printing parts

A method and apparatus for additive manufacturing wherein a fiber composite filament having an arbitrarily shaped cross section is softened and then flattened to tape-like form factor for incorporation into a part that is being additively manufactured.

Systems for additive manufacturing using feedstock shaping

A process of additive manufacturing in which a stack of non-planar layers of material are deposited for manufacturing an object. The non-planar layers can conform to the surface of the object or not. The non-planar layers can create structurally-advantageous interior structures in the object. The contours of the non-planar layers can be different or can be the same.

Method for additive manufacturing using filament shaping

The navigation of video and other types of content based on program moments and/or key content is contemplated. The contemplated navigation may be beneficial in facilitating use of key parameters to enhance user experience and navigation when performed through a video device, a set top box (STB), a digital video recorder (DVR), a Web service or other video accessing service/device.
