Additive manufacturing (AM) continues to make significant technology advancements and attract widespread interest in industry, academia, and the general media. However, the technology is likely still a decade away from attaining meaningful implementation in industry and has yet to find adoption in large-scale or partcritical manufacturing operations, such as airframe structural component production. As a bridge technology that takes advantage of existing manufacturing methods while AM is being fully developed, near-net manufacturing is a promising alternative. Near-net fills the gap between classic subtractive manufacturing and AM, and it may be accurately described in terms of grain size.
