Item Restricted IMPACT DE LA FABRICATION ADDITIVE SUR LA PERFORMANCE DE LA SUPPLY CHAIN(Université de Bordeaux, 2023-11-29) Noorwali, Albraa; Ducq, YvesAdditive Manufacturing (AM), often referred to as 3D printing, is a technology that allows for the direct creation of 3D products from digital models, offering industries new possibilities for design, customization, and rapid prototyping. Its impact spans industries such as aerospace, healthcare, and automotive, promising cost-effective production and innovative solutions. However, the quality of AM-produced products depends on the post-processing operation, and some non-quality issues are often encountered. Despite the extensive literature comparing AM to conventional manufacturing (CM), there is still a need for empirical evidence and comprehensive cost analyses to guide companies in adopting AM, especially by considering the non-quality issues. This thesis addresses this gap by (1) empirically investigating the impacts of AM across all supply chain processes by using collected data from a sample of 51 companies, (2) evaluating, by means of a simulation study and data from an oil and gas company, the practicality and cost-effectiveness of shifting from CM to in-house AM production while considering investment costs and different quality levels, and (3) exploring the advantages of integrating AM within a dual sourcing framework to assess cost implications and resilience benefits. The empirical investigation shows two major benefits of AM, namely: the ability to produce complex parts in low volumes and good design and the prototyping capability. Moreover, the simulation study provides evidence on the limits of AM when there is a low-quality level generated by postprocessing. The thesis enables as well to show the benefits of using AM within a dual sourcing context.21 0
