Abstract: Systems, methods, and new file formats are provided for printing 3D microstructures. In some implementations, a new file format is provided that defines 3D objects by a wireframe model expressed as a collection of wires. Because wires and their parameters are defined within the new file format, objects may be processed more efficiently and quickly to support 3D rendering operations. Such methods may be used to print new articles, such as eyelashes, bushes, swabs and other novel items.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design and manufacture of physical structures using toolpaths generated by reinforcement learning for use with subtractive manufacturing systems and techniques, include: obtaining, in a computer aided design or manufacturing program, a three dimensional model of a manufacturable object; generating toolpaths that are usable by a computer-controlled manufacturing system to manufacture at least a portion of the manufacturable object by providing at least a portion of the three dimensional model to a machine learning algorithm that employs reinforcement learning, wherein the machine learning algorithm includes one or more scoring functions that include rewards that correlate with desired toolpath characteristics comprising toolpath smoothness, toolpath length, and avoiding collision with the three dimensional model; and providing the toolpaths to the computer-controlled manufacturing system to manufacture at least the portion of the manufacturable object.

Abstract: In some embodiments, techniques are provided for verifying that a fabrication system can fabricate a proposed segmented design. A paintbrush pattern that represents capabilities of the fabrication system is determined. One or more forbidden patterns that the fabrication system is not capable of fabricating are determined based on the paintbrush pattern. The proposed segmented design is then searched for the forbidden patterns. If any forbidden patterns are found, the proposed segmented design is determined to not be fabricable by the fabrication system. If no forbidden patterns are found, then the proposed segmented design is determined to be fabricable by the fabrication system.

Abstract: A method is disclosed for additively manufacturing a composite structure. The method includes receiving from a user a sketch of a cross-section of the composite structure and a desired height. The method includes automatically generating a virtual model of the composite structure having a plurality of layers (1202), each with a thickness related to the height. The method further includes receiving from the user at least one infill pattern (1204) for at least one of the plurality of layers, and causing an additive manufacturing machine to deposit a continuous fiber along segments of the at least one infill pattern.

Abstract: A computing system (100) may include an access engine (108) and a toolpath reordering engine (110). The access engine (108) may be configured to access an original layer toolpath for slice of a 3D CAD object as well as a heat criticality measure (240, 340, 540) for the original layer toolpath. The heat criticality measure may specify a heat impact for different points on the multiple toolpath segments of the original layer toolpath for the 3D printing of the physical part using the original layer toolpath. The toolpath reordering engine (110) may be configured to reorder the multiple toolpath segments into a modified layer toolpath (250, 350, 550), and the modified layer toolpath (250, 350, 550) may have a heat criticality measure with a lesser heat impact on the physical part than the heat criticality measure (240, 340, 540) for the original layer toolpath.
