Abstract:
The goal of zero carbon operation of powertrain systems requires compatibility for Ethanol, Methanol and in particular Hydrogen as future energy carriers for internal combustion engines (ICE) as well as Fuel Cell systems. Future AM applications will include complex components in combination with high grade materials, such as high temperature, alcohol and hydrogen resistant steel and nickel alloys, for low and medium volume production.
Multi-material AM processes, combining multi-metal manufacturing, are subject of research programs and will support the mobility change by extending the applications to E-Motors, Fuel Cell systems and battery components.
Focus of the paper is on the application of metal-AM for prototype and small series of appropriate powertrain components providing material compatibility for CO2 neutral fuels. The motivation for the conversion from conventional to additive manufacturing is discussed in regard of functional optimization with AM-process related production design, as well as economically to achieve higher profitability.
