3D-Printed Catalysts Propel Hypersonic Flight

October 4, 2021

Ultra-efficient 3D printed catalysts could help solve the challenge of overheating in hypersonic aircraft and offer a revolutionary solution to thermal management across countless industries.

Developed by researchers at RMIT, the highly versatile catalysts are cost-effective to make and simple to scale.

To make the new catalysts, the team 3D-printed tiny heat exchangers made of metal alloys and coated them with synthetic minerals known as zeolites. When the 3D printed structures heat up, some of the metal moves into the zeolite framework – a process crucial to the unprecedented efficiency of the new catalysts.
