Advances in additive manufacturing have led to the potential to print items that are export controlled by the Nuclear Suppliers Group (NSG). Here we examine current metal powder additive manufacturing hardware and compare potentially manufactured items to those controlled by the NSG trigger list and dual use items list. In particular, we highlight the possibility of printing maraging steel baffles, endcaps and rotors for centrifuges to enrich uranium.Uranium enrichment is one of the most sensitive parts of the nuclear fuel cycle and producing reliable centrifuges is a notoriously difficult process. Uranium enrichment plants require centrifuges numbering in the hundreds and thousands and are still likely to be produced using traditional manufacturing methods in the near future. However, proliferant states have in the past shown willingness to pursue less than ideal solutions to covertly pursue the nuclear fuel cycle.
