Over the last decade, Additive Manufacturing has received an increased attention as many manufacturing companies have increasingly adopted new technologies to capture new opportunities. This research identifies the impacts of Additive Manufacturing (AM) on the supply chain when compared to the case of conventional manufacturing. Through an empirical investigation conducted with 17 multinational companies in the manufacturing sector, the impacts of AM are analysed by focusing on post-processing operations, lead times, cost implications and the use of the make-to-order & make-to-stock strategies. The empirical investigation reveals two major benefits of AM, namely: the ability to produce complex parts and the reduction of inventory levels. However, the empirical results were mixed for some other impacts of AM. In fact, although many experts agreed on the general benefits of AM, a significant number did not see much difference from the conventional methods. We also provide empirical evidence that, under AM, lead-times do not reduce as opposite to what is reported in the literature, which might be due to the extra time required for quality checks and post-processing.
