High thermal conductivity, low thermal expansion composites

This invention describes a special powder for 3D printing that creates materials with excellent heat transfer and low expansion. It combines metal particles with non-metal particles, specifically diamond. During the 3D printing process, a unique metal carbide layer forms directly between the diamond and metal, which helps heat move efficiently through the material.

Why it matters: The core challenge of reliably forming the precise intermetallic interface in situ during laser powder bed fusion, especially with diamond, likely remains a significant materials science and process control obstacle.

Status: Under examinationA pending application. It has not been granted, and it has not been abandoned.
How hard to build: SpecializedLaser powder bed fusion, material science, process control
