Additive Manufacturing allows the integration of precisely placed internal cooling channels into components. With the focus on automated post processing - removal of residual powder and surface smoothing of these channels the mechanical and chemical engineering departments of the Politecnico Milano (Italy) together with Rösler Italiana S.r.l. conducted a study with the surface treatment methods mass finishing, shot blasting and chemically supported mass finishing. The results clearly demonstrated that with all three methods a significant improvement of the overall surface quality could be achieved.

ith Additive Manufacturing (AM) advanced component geometries can be produced that are not possible with conventional manufacturing technologies. Among

other things it allows the creation of highly complex components with integrated functional features such as precisely placed cooling channels. These unique AM characteristics are of great interest for tool and die making, hydraulic components and the aerospace industry. Especially for the tool and die making industry the integration of cooling channels offers significant technical advantages, because temperature fluctuations during the cool down phase increase the risk of work pieces getting warped. Moreover, with a cooling system following the contours of a component, overall cool down times can be decreased considerably. Finally, because work piece faults like warping and Prototype manufactured with AM.

heat checks can be prevented, a more effective cooling function for injection molded components results in a higher overall component quality.
