Abstract: A computing system may include an access engine and a heat-aware toolpath engine. The access engine may be configured to access a slice of a 3-dimensional (3D) computer-aided design (CAD) object, wherein the 3D CAD object represents a physical part and wherein the slice represents a physical layer for 3D printing of the physical part. The heat-aware toolpath engine may be configured to generate a layer toolpath to control the 3D printing of the physical layer, including by partitioning the slice into zones and determining a zone order, based on a heat-aware criterion, for the layer toolpath to traverse for the 3D printing of the physical layer. The heat-aware toolpath engine may also be configured to provide the layer toolpath to support the 3D printing of the physical part.

Abstract: Methods for computer-aided design, engineering, visualization, or manufacturing (CAx) operations and corresponding systems and computer-readable mediums are disclosed herein. A method includes receiving, by a data processing system, a computer-aided design, engineering, visualization, or manufacturing model of a product to be manufactured. The CAx model comprises a bridge structure and at least two leg structures. The method includes slicing the CAx model into a plurality of layers, wherein each layer in each leg structure has a corresponding layer number in a sequence of layer numbers for that leg structure. The method includes maintaining an association between corresponding layer numbers of each of the leg structures. The method includes manufacturing the product according to the sequence of layer numbers and the associations, including manufacturing at least one layer of each leg structure in turn. Each leg structure completes manufacture at substantially the same time.

Abstract: Systems and methods for designing and manufacturing an additive manufacturing (AM) model. A method includes computing a wedge plane and initial toolpath for an AMmodel based on a breaking angle. The method includes trimming an excess toolpath of the AM model using a breaking plane. The method includes building the toolpath along the normal of a first layer and trimming based on a next layer. The method includes building a next wedge of the toolpath in the direction of a wedge plane used to trim a previous wedge The method includes storing the toolpath.

Abstract: A component of a computer-aided manufacturing (CAM) system may be configured to cause a processor to generate instructions that specify how a 3D-printer additively builds an article on a build plate via depositing material from a deposition head. The 3D printer is configured to cause the deposition head to rotate in order to selectively change, an angle of a deposition axis at which the deposition head outputs material. The generated instructions specify how the deposition head is operated by the 3D printer to build the article on the build plate such that material deposited along a side wall surface of the article is provided by the deposition head having its deposition axis orientated at an angle determined based at least in part on an angular orientation of the side wall surface.

Abstract: A component of a computer-aided manufacturing (CAM) system may be configured to cause a processor to generate instructions that specify how a 3D-printer additively builds an article on a build plate via depositing material from a deposition head. The generated instructions specify how a deposition head and/or a build plate of the 3D printer moves relative to each other to build an article on the build plate such that material outputted from the deposition head is deposited in successive layers in a build direction. The processor may receive a user selection of a spiral pattern selection. For at least portions of each layer of at least a portion of the article, the generated instructions specify that the deposition head continuously deposits material in a spiral pattern between radially outward and radially inward portions of the article.
