This work investigates the causes of excessive wear occurring at the rocker arm/pushrod and rocker arm/valve interfaces of a diesel engine for industrial cleaning machines, after only 1000 h of engine operation. In this engine, the recent replacement
Due to the high complexity of the Additive Manufacturing processes, the effect of individual deposition parameters on integrity and mechanical performance of the 3D-printed part is not easily assessable. An energy density-based approach is often adop
