What FATHOM does

Fathom Manufacturing, LLC is a U.S.-based, privately held advanced contract manufacturer headquartered in Hartland, Wisconsin, with eight production sites across the country totaling more than 450,000 square feet of manufacturing space. The company consolidates 25+ production technologies — including polymer and metal 3D printing (SLS, SLA, FDM, MJF, PolyJet, DMLS), 3- to 5-axis CNC machining, EDM, photochemical machining, sheet metal fabrication, injection and urethane molding, die casting, extrusion, assembly, and inspection — into a single-source offering for low-volume, high-mix, mission-critical components. It is owned by private equity firm CORE Industrial Partners, which assembled the platform through the 2019 merger of Fathom, Midwest Composite Technologies, and ICOMold, followed by the 2020 acquisition of GPI Prototype and the 2021 acquisition of Summit Tooling & Summit Plastics.

The company targets regulated, high-stakes end markets — aerospace and defense, medical devices, robotics and automation, semiconductor capital equipment, automotive and EV, and ICT and energy — selling through white-glove enterprise field sales rather than algorithmic quoting. Every quote is reviewed by an experienced engineer for manufacturability optimization. Revenue is generated through project-based contract manufacturing, engineering consulting, tooling, and the recently launched Fathom Edgeworks global sourcing service. Certifications (ISO 9001:2015, ISO 13485:2016, AS9100D, ITAR, NIST 800-171) and a named customer roster spanning 3M, Tesla, Stryker, Applied Materials, Blue Origin, Edwards Lifesciences, Lucid Motors, Intel, Safran, and Leonardo DRS anchor its position in qualified-supplier programs. The 2026 Rochester/Finger Lakes expansion signals continued geographic and aerospace/defense vertical deepening under CORE Industrial Partners' ownership.

Broad incumbents

• Jabil: Large-scale global contract manufacturer offering design, engineering, and manufacturing services across multiple industries including 3D printing, CNC, and assembly. Overlaps with Fathom's contract manufacturing and engineering services but at much larger scale and broader scope.
• Sanmina: Global end-to-end manufacturing solutions provider serving medical, aerospace, defense, and industrial markets. Overlaps with Fathom's regulated-vertical contract manufacturing, precision machining, and assembly capabilities at significantly larger scale.
• Flex (Flextronics): Global contract manufacturer offering design, manufacturing, assembly, and supply chain services across multiple verticals including ICT, automotive, and medical. Overlaps with Fathom's contract manufacturing and ICT vertical, but operates at significantly larger global scale.

Direct peers

• Sintavia: Aerospace & defense-focused additive manufacturer with AS9100/Nadcap certifications. Comparable in regulated-vertical focus (aerospace/defense) and 3D printing depth, though smaller and more vertically specialized.
• Xometry: AI-driven on-demand manufacturing marketplace connecting buyers with CNC, 3D printing, injection molding, and sheet metal suppliers. Directly competes for the same high-mix, low-volume enterprise customers with a more automated, marketplace-based model.
• Hubs (Protolabs): Online manufacturing platform (now part of Protolabs) offering CNC, 3D printing, injection molding, and sheet metal services globally. Directly competes in the digital manufacturing service-bureau space with a marketplace model.
• Stratasys Direct Manufacturing: Stratasys-owned 3D printing service bureau offering FDM, PolyJet, SLA, SLS, and DMLS parts. Directly comparable 3D printing service offering, leveraging Stratasys's installed base of printers — Fathom's partner/competitor dynamic.
• Protolabs: Direct peer offering on-demand digital manufacturing services (CNC, 3D printing, injection molding, sheet metal) with automated quoting. Closest comparable in business model, target customers, and technology breadth — both serve engineers needing prototype-to-production parts.

Emerging players

• Markforged: Industrial 3D printer manufacturer with growing Digital Forge platform and manufacturing services. Partial overlap in metal and composite 3D printing services for industrial customers; primarily a printer OEM with adjacent services.
• Velo3D: Metal additive manufacturing company that both produces printers and offers contract manufacturing services. Partial overlap as a 3D printing service provider in aerospace/space — comparable technology focus though different go-to-market model.
