Alpine adopts monolithic 3D printed intake system for Alpenglow Hy6 hydrogen engine
CRP Technology and CRP Meccanica worked with Alpine to develop a monolithic intake plenum and manifold system for the Alpenglow Hy6, a hydrogen-powered rolling prototype. The previous design had problems with sealing during testing because the 3D printed plastic parts and glued aluminum edges expanded and vibrated differently at the joints.
Alpine moved to a single-material architecture using SLS with carbon-fiber-reinforced thermoplastic Windform SP. The redesign required only minor shape changes, along with built-in flanges and walls of uniform thickness, to reduce differences in how they flex under high-pressure conditions
