Printing components for reciprocating engine applications

Engines, no matter what their configuration, can be defined as machines used to convert hydrocarbon fuels into mechanical motion. The generated motion can be a rotational torque (as in a reciprocating engine) or thrust (from a turbine). The combustion of hydrocarbon fuels in an engine produces environments consisting of extremely hot and pressurized gas, which often include highly reactive chemical species, such as carboxylic and sulfuric acids. The materials used in the construction of engines must be able to withstand these extremes in temperature, pressure, and chemistry. Outside of the combustion chamber, engine components are subjected to cyclic loads, friction and wear, and torsion. As a result, metals, especially high-strength steels, are predominantly used in engine construction.
