摘要： A system and method for improving additive manufacturing, including additive manufacturing toolpaths, is provided. The system and method includes a toolpath generator that obtains initial toolpaths of an object, identifies isolated paths in the toolpaths, and adds bridge connections between neighboring isolated paths in each layer to improve the toolpaths. The bridge connections facilitate the continuous and non-stop deposition of each layer according to improved toolpaths during additive manufacture, which can reduce total deposition time and improve the resultant additive manufacture.

摘要： A simulation-assisted additive manufacturing system and method for generating an anisotropic compensation to account for non-uniform deformation due to additive manufacturing and service loading. The predicted deformation may not be fully defined. The present disclosure provides a system and method for estimating the missing deformation data through regression analysis. The present disclosure also provides an integrated framework where the various simulated-assisted design modules are configured for two-way communication and sharing access to changes to the model.

摘要： A method of forming a low-density three-dimensional article is provided. The method includes printing a low-density composition on a substrate to form at least one layer comprising the low-density composition. The low-density composition includes a (P) polymer component and (M) a microsphere component in a ratio by volume (P):(M). The method also includes selectively controlling a density of the low-density composition during printing to give the at least one layer on the substrate. Selectively controlling the density of the low-density composition includes varying the ratio (P):(M) during printing. The method further includes repeating the printing and selectively controlling the density of the low-density composition to form additional layer(s), thereby forming the low-density three-dimensional article. A low-density three-dimensional article prepared in accordance with the method is also provided.

摘要： An additive manufacturing extrusion head that includes a heated nozzle for accepting a feedstock and extruding the feedstock onto a substrate at a deposition plane, the nozzle having a longitudinal extrusion axis. A reciprocating platen surrounds the nozzle, the platen operable to reciprocate along the extrusion axis at or above the deposition plane as the nozzle extrudes feedstock onto the substrate; and wherein the platen flattens the extruded feedstock such that it does not protrude above the deposition plane as the extrusion head traverses over the substrate.

摘要： An additive manufacturing machine includes a nozzle assembly with a noncircular, rotatable outlet. The nozzle assembly deposits a bead of material having a width that is defined by the angular orientation of the noncircular shaped outlet with respect to the material deposition path direction. The combination of high material deposition rate and fine resolution save time and energy while also producing high-quality parts.

摘要： Several examples of an article of manufacture made with an additive manufacturing machine are disclosed. A length of fiber reinforcement is provided to a nozzle. The fiber reinforcement is embedded into a stream of a base polymer material at the nozzle and deposited as a bead of composite polymer material having fiber reinforcement. The fiber reinforcement may be dry or pre-impregnated with a reinforcing polymer. The additional strength of the composite polymer material having fiber reinforcement allows for true, three-dimensional printing of articles having unsupported regions.

摘要： Hydraulic actuation systems having variable displacements and energy recovery capabilities include cylinders with pistons disposed inside of barrels. When operating in energy consuming modes, high speed valves pressurize extension chambers or retraction chambers to provide enough force to meet or counteract an opposite load force. When operating in energy recovery modes, high speed valves return a working fluid from extension chambers or retraction chambers, which are pressurized by a load, to an accumulator for later use.

摘要： Methods and compositions for additive manufacturing that include reactive or thermosetting polymers, such as urethanes and epoxies. The polymers are melted, partially cross-linked prior to the depositing, deposited to form a component object, solidified, and fully cross-linked. These polymers form networks of chemical bonds that span the deposited layers. Application of a directional electromagnetic field can be applied to aromatic polymers after deposition to align the polymers for improved bonding between the deposited layers.
