ADDMAN Engineering

What ADDMAN Engineering does

ADDMAN Engineering, LLC is a vertically integrated contract manufacturer combining additive manufacturing (metal and polymer 3D printing), precision CNC machining, injection molding, and urethane casting under a single platform. Founded in 2020 by private equity sponsor American Industrial Partners (AIP) and headquartered in Fort Myers, Florida, the company operates 8 facilities across the United States with more than 550 employees and over 160 industrial additive manufacturing systems. It serves mission-critical end markets including aerospace & defense, commercial space, medical, energy, and industrial through B2B enterprise field sales targeting engineering and procurement teams at prime contractors and OEMs.

ADDMAN's technology stack spans every major additive modality — LPBF for metals, plus MJF, FDM, SLA, DLP, SLS, DLS, PolyJet, and HPS for polymers — alongside traditional CNC (3- to 7-axis and EDM) and injection molding with in-house tooling. Differentiated capabilities include proprietary ADDCAAM patented slicing software (commercialized through Create it REAL as a REALvision Pro plugin), a proprietary Super C103 refractory alloy process with material properties exceeding wrought equivalents, and the largest concentration of AMUG Distinguished Innovator Operator (DINO) awardees in the industry. The platform is organized into operating divisions — ADDMAN Polymer, ADDMAN Advanced Metals, ADDMAN Precision — and incorporates acquired brands Castheon (refractory metals and hypersonics), Keselowski Advanced Manufacturing / KAM (metal AM), Dinsmore (polymer AM), HARBEC (precision machining and injection molding), and Forecast 3D (polymer AM acquired from GKN Powder Metallurgy in late 2025).

Revenue is generated primarily through project-based professional services for contract manufacturing, with quote-based pricing tied to part complexity, material, and volume, plus milestone-based payment terms (e.g., 20/30/50 for metal AM). A licensing/royalty stream exists for ADDCAAM software. Customers span named enterprise primes (Boeing, Firefly Aerospace, Mercury Systems, US Navy), commercial OEMs, and smaller commercial users, with regulatory qualifications including ITAR, AS9100D, NADCAP, ISO 13485, and ISO 9001:2015 enabling participation in flight-critical defense and regulated medical work.
