Thermoacoustic Sterling Engine Is Now Fully 3D Printable

A hobbyist's thermoacoustic Stirling engine project has been updated so that the burner and hot end are now designed for SLA metal printing, making the entire engine 3D printable. The design integrates a biogas/methane burner directly inside the printed hotend, enabling an efficient heat exchange geometry that would be difficult to achieve otherwise. Plans, a Discord, and a forum for collaborating on the open-source design are hosted at OwnEnergy.org, which also documents the creator's homescale biogas plant that powers the engine.
