Rennscot Manufacturing bridges the gap between additive manufacturing as an innovation tool and additive as a production method. The Woburn, Massachusetts, contract manufacturer runs four EOS laser powder bed fusion (LPBF) machines today, with space wired for 12, and is on track to earn 80% more revenue in 2026 than in 2025. Its playbook: Skip design, target qualified applications, standardize on one machine builder and 2-3 material families, and avoid mixing powder lots to eliminate variability. The firm also positions machining expertise as a postprocessing advantage for organically shaped additive manufacturing (AM) parts. The goal is to flip its revenue mix from 80% machining to roughly 80% additive and additive postprocessing by the end of the decade.
