This week's What We're Watching pick takes you inside Hyliion's Austin headquarters, where additive manufacturing is turning a once-impossible generator design into a production reality.

In this exclusive factory tour, see how 3D printing—including Colibrium Additive's M Line printers—is producing the critical heat exchangers and cooling components inside the KARNO generator, a fuel-agnostic system built on a linear Stirling-engine architecture. The payoff: component geometries traditional machining couldn't achieve, tighter tolerances, less material waste, and a manufacturing process built to scale as Hyliion moves toward customer deliveries.

For plant managers and engineers evaluating distributed power and microgrid options—or anyone tracking how additive manufacturing is moving from prototyping into full production—this is a look at what that transition actually looks like on the shop floor.
