Title: Method of manufacturing a micro heatsink by an additive process

Abstract

A method of producing a complex product includes designing a three dimensional preform of the complex product, creating a three dimensional preform of the complex product using the model, depositing a material on the preform, and removing the preform to complete the complex product. In one embodiment the system provides a complex heat sink that can be used in heat dissipation in power electronics, light emitting diodes, and microchips.

Systems for mechanical logic based on additively manufacturable micro-mechanical logic gates

Patent Pascall, Andrew; Mancini, Julie; Panas, Robert Matthew; ...

The present disclosure is directed to various mechanical logic gates. In one example a mechanical logic NOT gate system is formed which has a first pair of bi-stable buckling structures each being operatively connected at a first connection point thereof to one another, and also to a first rigid structure at second connection points, the first rigid structure being held stationary. A second pair of bi-stable buckling flexures is each operatively connected at first connection points thereof to each other and at second connection points thereof to a second rigid structure being held stationary.

Hybrid additive manufacturing methods using hybrid additively manufactured features for hybrid components

Patent Lacy, Benjamin Paul; Kottilingam, Srikanth Chandrudu; Schick, David Edward

A hybrid additive manufacturing method comprises building an additive structure on a pre-sintered preform base, wherein building the additive structure comprises iteratively fusing together a plurality of layers of additive material with at least a first layer of additive material joined to the pre-sintered preform base, and wherein the pre-sintered preform base comprises an initial shape. The hybrid additive manufacturing method further comprises modifying the initial shape of the pre-sintered preform base comprising the additive structure into a modified shape comprising the additive structure, and, joining the pre-sintered preform base in its modified shape to a component.
