Abstract


Purpose - The purpose of this paper is to investigate the possibility of in situ flaw detection for powder bed, beam-based additive manufacturing processes using a thermal imaging system. Design/methodology/approach - The authors compare infrared images (IR) which were taken during the generation of Ti-6Al-4V parts in a selective electron beam melting system (SEBM) with metallographic images taken from destructive material investigation. Findings - A good match is found between the IR images and the material flaws detected by metallographic techniques. Research limitations/implications - First results are presented here, mechanisms of flaw formation and transfer between build layers are not addressed in detail. Originality/value - This work has important implications for quality assurance in SEBM and rapid manufacturing in general. © Emerald Group Publishing Limited.
