3D printing and additive manufacturing have completely changed modern supply chain practices, especially in consideration to manufacturing. Proposed tariff increases will likely accelerate this impact. Additive manufacturing has become more common in every industry including the production of fasteners. These added tariffs could accelerate the automation currently taking place as well as put pressure on 3D printing manufacturers to make their printers use as little material as possible. Businesses are always challenged with finding new solutions to adapt to a changing environment whether it be legislation, consumer wants/needs or economic factors. In this case, these tariffs could encourage fastener manufacturers to invest in additive manufacturing to keep the need for costly raw materials as low as possible. Effected fastener companies who would invest in 3D printing may be eligible to take advantage of the Research and Development Tax Credit.
