Airwolf 3D has a loyal customer following, built on the company's reputation for high-quality 3D printers. Geoffrey Shulz, one of these loyal customers, is looking to a retirement filled with more time for 3D printing projects, and lately brought his creative drive together with his love for locomotives. He has designed and created a 3D printed steam engine, initially to teach his son how steam engines function, but also to eventually power a fully 3D printed locomotive. The engine can run off just 5 psi of air pressure and includes as Stephenson valve that allows it to run in reverse.
