    Abstract: Systems and methods in accordance with embodiments of the invention implement additive manufacturing techniques that employ different sets of deposition characteristics and/or material formation characteristics during the additive manufacture of an object so as to strategically build up the object. In many embodiments, material used to build up an object is deposited at different deposition rates during the additive manufacture of the object, and the object is thereby strategically built up. In one embodiment, a method of additively manufacturing an object includes: depositing material onto a surface at a first deposition rate so as to define a first region of the object to be additively manufactured; and depositing material onto a surface at a second deposition rate so as to define a second region of the object to be additively manufactured; where the second deposition rate is different from the first deposition rate.

    Abstract: Systems and methods in accordance with embodiments of the invention fabricate objects including amorphous metals using techniques akin to additive manufacturing. In one embodiment, a method of fabricating an object that includes an amorphous metal includes: applying a first layer of molten metallic alloy to a surface; cooling the first layer of molten metallic alloy such that it solidifies and thereby forms a first layer including amorphous metal; subsequently applying at least one layer of molten metallic alloy onto a layer including amorphous metal; cooling each subsequently applied layer of molten metallic alloy such that it solidifies and thereby forms a layer including amorphous metal prior to the application of any adjacent layer of molten metallic alloy; where the aggregate of the solidified layers including amorphous metal forms a desired shape in the object to be fabricated; and removing at least the first layer including amorphous metal from the surface.

    Abstract: Harmonic drives (HDs) are used widely in robotics as a method for achieving high gear reductions and for driving force transmissions. The HD is made a three components: a wave generator, a flexspline, and a circular spline. Low-cost wave generators for metal strain wave gearing are provided. Wave generators are provided that incorporate commercially available bearings that form an ellipse either statically or through adjustment. Wave generators are optimized to maximum performance, including increasing the efficiency and the lifetime, while maximizing the running torque. The shape, size, number, type and location of the bearings can be changed so that the wave generator fails at a similar lifetime as a low cost flexspline. The shape of the wave generator may be adjusted to change the performance of the strain wave gear. The combination of low-cost flexsplines with low-cost wave generators reduces the cost of the strain wave gear.
