Hyliion installs first US M Line from Colibrium Additive to scale KARNO generator production
January 16, 2025

Hyliion Holdings Corp, developer of the KARNO clean energy generator, based in Austin, Texas, USA, has taken delivery of an M Line Additive Manufacturing machine from Colibrium Additive – a GE Aerospace company based in Lichtenfels, Germany. The new machine, purchased to support production of the KARNO generator, marks the first deployment of an M Line system in the United States.
Hyliion has placed orders for additional M Line machines, with deliveries scheduled to continue throughout 2025.
The company installed an X Line 2000R from Colibrium in April 2024, and the adoption of the advanced M Line machines will streamline full-scale production.
“We are proud to support Hyliion with our M Line technology,” stated Chris Schuppe, CTO of Colibrium Additive. “Featuring a modular design that separates Laser Processing and Material Handling systems, these machines aim to streamline operations, reduce production times, and optimise manufacturing processes, making them an optimal choice for producing the KARNO generator’s complex parts in full-scale production.”

The highly efficient performance of Hyliion’s KARNO linear generator is made possible by the complex geometries of its critical components, achievable only through metal Additive Manufacturing.
“The M Line systems are a pivotal advancement in Hyliion’s journey to scale manufacturing,” said Thomas Healy, Founder and CEO of Hyliion. “By incorporating this state-of-the-art technology in our production process, we are significantly enhancing our capacity to meet the growing demand for our KARNO generators in 2025 and beyond.”
Hyliion’s KARNO generator is designed to efficiently produce electricity using one of over 20 available fuel sources, leveraging advanced thermal and power systems engineering. The generator is expected to offer on-demand AC or DC power with high efficiency and a cleaner emissions footprint as compared to a conventional genset, representing the future of low-emission energy generation.
