摘要： A manufacturing method of an acoustic coating in an ordered array of interconnected micro-channels intended to receive, on a reception surface, an incident acoustic wave with direction Ac normal to this surface, the method including depositing a sacrificial material on a substrate surface to form a three-dimensional scaffold of filaments, infiltrating at least one part of the three-dimensional scaffold with a thermosetting material, solidifying the thermosetting material to form a solidified material, and removing the sacrificial material from the solidified material to form the ordered array of interconnected micro-channels, the filaments forming by superimposed layers the three-dimensional scaffold being, for a given layer of filaments, oriented in a direction forming, in a plane formed by the layer, a first angle θ relative to the direction Ac of the incident acoustic wave, to confer acoustic properties to the ordered array of interconnected micro-channels and thus form the acoustic coating.

摘要： According to some aspects, techniques are provided for fabricating sinterable metallic parts through the application of directed energy to a build material. In particular, applying energy to a build material comprising a polymer mixed with a metal powder may cause the polymer to form a cohesive structure with the metal powder. As a result, the polymer acts as a “glue” to produce a metallic green part without local melting of the metal. The green part may subsequently be sintered to remove the polymer and produce a fully dense metal part. Optionally, a step of debinding may also be performed prior to, or simultaneously with, sintering.

摘要： Technologies are described for a method of making an encapsulated reactant having a desired shape or size. The method comprises providing solid reactant particles and an encapsulating material. The encapsulating material is heated above its solidification temperature to form a molten, semi-solid, or liquid encapsulating material. The solid reactant particles are added to the molten, semi-solid, or liquid encapsulating material and mixed to disperse the solid reactant particles in the encapsulating material and form a mixture. The mixture may be extruded or formed into the desired shape or size of the encapsulated reactant, or the mixture may be solidified and extruded, granulated, shredded, ground, or pressed into the desired shape or size.

摘要： A method of supporting a cantilevered component mounted to a hub by locating a cassette in proximity to the cantilevered component, the cassette defining a volume for filling with an encapsulant; filling the volume with an encapsulant material; and causing the encapsulant to solidify to the cantilevered component to support the cantilevered component. The cantilevered component is preferably a blade on a bladed disc and the encapsulant provides support to change the vibration response of the blade during a subsequent machining step.
