Abstract: A system for making a build using directed energy deposition is provided. The system includes a primary heat source; a processing nozzle movable relative to the build for delivering a metal powder, a carrier gas for the metal powder, and a shield gas to the build; a melt pool sensor for providing information regarding a temperature of a melt pool of the build; a secondary heat source separate from the primary heat source positionable relative to the build for delivering heat to a selected area of the build; a cooling source positionable relative to the build for delivering a cooling fluid to a selected area of the build; and a control system for operating the primary heat source, the secondary heat source and the cooling source to maintain a desired temperature profile for the build. The system preferably includes a temperature sensor for providing a temperature profile of the build.

Abstract: Provided herein are compounds that exhibit activity as fungicides and are useful, for example, in methods for the control of fungal pathogens in plants and can be applied to said plants in a variety of ways.

Abstract: A powder delivery system for use in an additive manufacturing device includes a powder control valve configured to selectively divert at least a portion of an input fluid flow to a return line while a remainder of the input flow is delivered to a delivery nozzle. In some embodiments, the powder delivery valve may be modulated to alter the percentage of input flow diverted to the return line. Alternatively, the powder delivery valve may be either fully open or closed. In each embodiment, the powder delivery valve permits rapid changes in the amount of powder delivered to the nozzle.
