Advancements in Metal 3D Printed Micro-Gas Chromatography Columns ID: 2021-041

This technology presents a novel method for fabricating metal 3D printed micro-gas chromatography columns that are robust under thermal cycling.

Technology Overview

The technology developed by Brigham Young University involves the use of binder jet technologies for fabricating metal 3D printed micro-gas chromatography columns, with a focus on bronze infiltration to create sealed, robust metal microchannels. This method controls the infiltration of bronze using sacrificial powders and structures, ensuring gas-tight interfaces without obstructing microchannels, thus maintaining structural integrity and enhancing the functionality of micro-gas chromatography.
