Abstract: A method of replacing at least one tooth of a gear includes providing a tool jig including a mounting block with a plurality of indexing jig features. The tool jig also includes a tool-supporting feature in laterally movable contact with a jig rail feature. With at least one indexing jig feature, relative motion of the tool jig relative to the gear is resisted. A material-removal tool is operated, while attached to the tool-supporting feature in the tooth-removal position, to remove at least a portion of a working circumference of the gear including a native gear tooth to be replaced. Motion of the material-removal tool is guided to generate a circumferential gear cut including a relatively smooth first cut surface formed by removal of at least the native gear tooth to be replaced. The material-removal tool is removed from the tool-supporting feature. The tool jig is removed from the gear.

Abstract: A method of forming a dual cure three-dimensional object by additive manufacturing may be carried out by mixing a first precursor liquid and a second precursor liquid to produce a polymerizable liquid comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component (e.g., a second reactive component) that is different from the first component (e.g., that does not contain a cationic photoinitiator, or is further solidified by a different physical mechanism, or further reacted, polymerized or chain extended by a different chemical reaction). In the foregoing: (i?) at least one reactant of the second solidifiable component is contained in the first precursor liquid, and (ii?) at least one reactant or catalyst of the second solidifiable component is contained in the second precursor liquid. Once mixed, the three-dimensional object may be formed from the resin by a dual cure additive manufacturing process.

Abstract: Automated camera-based optical assessment involves color assessment of a physical object using conventional and inexpensive computer hardware such as a smartphone. A specially-configured test card includes a body supporting a reagent pad configured to change to an expected color in response to an enzymatic reaction, and an imaging key adjacent the reagent pad. The imaging key includes color fields including at least one field of the expected color. The hardware captures an image of the test card, and processes the image to identify the reagent pad and color fields, to process a brightness calibration target, to determine color values for the reagent pad and color fields, to calibrate the color values as a function of brightness and/or color by comparison to the brightness and color calibration targets, and to identify a color field most closely matching the reagent pad's color to determine a corresponding test result.
