Hyliion CEO says company would not have a product without additive manufacturing

Hyliion CEO Thomas Healy stated on the Additive Insight podcast that the company would not have a product without additive manufacturing. Hyliion, a publicly listed manufacturer of clean modular power generation systems, acquired the KARNO Generator technology from GE Aerospace in 2022. That acquisition included significant metal additive manufacturing capacity, which was used for early development and is now deployed to produce commercial products like the KARNO 200 kilowatt power module. Healy noted that Hyliion has scaled to a fleet of three dozen metal AM systems for production.

This case is a direct extension of the GE Aerospace qualification grind pattern, where AM success becomes infrastructure rather than a headline. Hyliion inherited both the technology and the AM production capability from GE Aerospace, demonstrating how AM can be embedded as a core manufacturing process from the start of a product's commercial life. The company operates in the energy vertical, a fragmented and early-stage AM adoption segment, but its reliance on AM for a commercial product is notable. The fleet of 36 metal LPBF systems represents a meaningful production-scale deployment, not a pilot or prototyping setup.

For the AM industry, Hyliion's case is a concrete example of AM being the only viable manufacturing route for a specific product, not a substitute for conventional methods. The company must now demonstrate that this AM-dependent production model can achieve the reliability, cost, and throughput required for energy-sector customers. The key question is whether Hyliion can maintain this production advantage as it scales beyond the current fleet size and into higher-volume demand.
