Abstract

Additive Manufacturing has become an appropriate process for manufacturing complex parts and repairing high-value-added components in recent years. However, the possibilities offered by this process go further and lately it has begun to be used for the combination of different materials. Additional manufacturing allows the material to be added in a localized manner, and it is therefore possible to deposit at the base of a particular material layers or circuits of a second material that offer special properties. In order to take a further step in this area, this study examines the capacity to control the resulting thermal field by localized deposition of copper on a Invar 36 substrate. To this end, an Invar 36 test part has been manufactured by additive manufacturing, and the model of finite elements has been validated with it. In a second step, using the same model, the cooling capacity of copper tracks in different forms has been assessed and the ability to control the thermal field on the surface of the piece has been guaranteed through double circuits, i.e. cooling and heating circuits. Thus, the capacity of additive manufacturing to produce multi-material structures has confirmed that the manufacture of parts with specific thermal properties and behavior is possible.
