Abstract

Laser ablation considered as a subtractive process working alongside an additive system promotes the geometric integrity of components and compliance with the nominal design. The strategy chosen to remove build deviations has a fundamental role towards streamlining efficient digital workflows for layer-wise manufacturing of high-quality components. A variable slicing algorithm is proposed for the adaptive ablation of in-process reconstructed over-sized volumes considering the laser-material interaction, a layer manufacturing priority list and volume characteristics. A first verification shows that the flexible change of the ablation slicing strategy hold potential for implementation within a hybrid process chain for additive manufacturing.
