A thermal management system for a gas turbine engine includes an additively manufactured nacelle component, at least a portion of the additively manufactured nacelle component forming an additively manufactured heat exchanger that extends into a fan bypass flow.

The present disclosure provides mixtures, systems, and methods for printing a three-dimensional (3D) object. In some aspects, the present disclosure provides a mixture for printing a 3D object, comprising a plurality of granulated particles. In some aspects, the present disclosure provides a mixture for printing a 3D object, comprising a plurality of precursor compounds configured to react to form a plurality of particles.

Support substrates are used in certain additive fabrication processes to permit processing of an object. For additive fabrication processes with materials that are sintered into a final part, a multi-layer support substrate of interleaved support and interface layers is fabricated to support an object while reducing an impact of friction on shrinkage of the part during the sintering process.

The present invention relates to a suspension comprising 50-95% by weight of the total suspension (w/w) of at least one metallic material and/or ceramic material and/or polymeric material and/or solid carbon containing material; and at least 5% by weight of the total suspension of one or more fatty acids or derivatives thereof. In addition, the invention relates to uses of such suspension in 3D printing processes.

The invention relates to a plausibility checking method for rapid prototyping devices, in particular for stereolithography devices. In this connection, input data (14) is checked which is present particularly in the form of graphics data and of which every file renders a layer. Every layer comprises a plurality of pixels. The component to be printed in the respective layer is produced based on output data by the rapid prototyping device. The input data of two consecutive layers is checked and the sum of all pixels to be exposed is determined for every layer. A signal (22) is output in particular as a warning signal (26) when the pixel sum of a following layer is larger than in the previous layer by a predetermined factor.

A method for manufacturing a part by alloying a precious metal with boron, wherein: a quantity of precious metal reduced to powder form is provided; a quantity of a nano-structured micrometric boron powder is provided; the precious metal powder is mixed with the nano-structured micrometric boron powder to obtain a mixture; the mixture is compacted by applying a uniaxial pressure; the mixture is subjected to a spark plasma sintering or flash sintering treatment, or to a hot isostatic pressing (HIP) treatment, to obtain an ingot of a precious metal/boron alloy, and the ingot is machined to obtain the part, or the ingot is reduced to powder form by a micronisation treatment and the powder is treated to obtain the part. Additionally, a gold/boron alloy.
