Scratching the Surface: How Surface Engineering Fills in the Gaps that AM Leaves Behind
Prior to 3D printing’s arrival on the manufacturing scene, the US military supply chain was often met with lengthy and arduous timelines for critical asset production. This not only stalled the manufacture and repair of essential equipment within the military supply chain, but it also impeded military readiness, and with high price tags to boot.
