Abstract Scope |
It has long been known that it is possible to manipulate the local thermomechanical conditions during laser powder bed fusion by locally adapting the process parameters. A major limitation has been that the primary function of the laser is to consolidate the material into fully dense parts, which inherently limits the range of parameter variation that can be leveraged for microstructural control. In dual laser systems, the consolidation and tailoring of the thermal conditions can be decoupled across both lasers, which increases the opportunity for microstructural control. This talk will explore the possibilities, but also the limits of dual laser scan strategies to locally manipulate the microstructure using simulations as a guide, with verification from experimental examples for Ti6Al4V and super duplex stainless steel. |
