Abstract: Methods for the fabrication of metal strain wave gear flexsplines using a specialized metal additive manufacturing technique are provided. The method allows the entire flexspline to be metal printed, including all the components: the output surface with mating features, the thin wall of the cup, and the teeth integral to the flexspline. The flexspline may be used directly upon removal from the building tray.

Abstract: A cutting tool with a plurality of cutting elements connected to a support structure wherein a portion of the support structure is configured to flex or bend based on the rotational frequency of the cutting tool. The rotational frequency of the cutting tool is a product of the design and composition of the tool.

Abstract: A cutting tool with a cutting region and a connecting support region where the support region is designed to connect to an external motor assembly. The cutting tool is also has a porous region that is integrated within a portion of the tool such that as the tool cuts material the porous region can allow samples of the cut material to permeate into an internal chamber of the tool. Once in the internal chamber material samples can be analyzed in-situ for direct composition analysis.

Abstract: Systems and methods for developing tough hypoeutectic amorphous metal-based materials for additive manufacturing, and methods of additive manufacturing using such materials are provided. The methods use 3D printing of discrete thin layers during the assembly of bulk parts from metallic glass alloys with compositions selected to improve toughness at the expense of glass forming ability. The metallic glass alloy used in manufacturing of a bulk part is selected to have minimal glass forming ability for the per layer cooling rate afforded by the manufacturing process, and may be specially composed for high toughness.
