Fathom offers 3D printing and advanced manufacturing services in Milwaukee, WI, operating from its headquarters facility in Hartland, Wisconsin. As Fathom’s most comprehensive U.S. manufacturing site, this location brings together additive manufacturing, precision CNC machining, EDM, assembly, finishing, and inspection under one roof.
The facility supports your program at any stage, from early prototyping and DFM through bridge production, low-volume runs, and full-scale manufacturing. It also offers full post-processing, finishing, and assembly services. You get a single partner who stays involved from the first design review through final delivery.
The facility produces a wide range of complex components for demanding programs, including:
Fathom‘s Milwaukee-area facility operates 57 additive manufacturing machines spanning FDM, SLS, DMLS, and HP-MJF technologies. That range means engineers can select the right process for the application rather than working around a single-technology supplier.
Post-processing and finishing are handled entirely in-house, and the facility can deliver 3D-printed parts as fast as the next business day.
The CNC operation at Fathom’s Milwaukee-area facility is built around large, complex parts. The floor includes 20 three-axis vertical machining centers, 3 five-axis vertical machining centers, 8 wire EDM machines, 2 sinker EDM machines, and 1 two-axis lathe, with capacity to handle parts up to 6 feet by 10 feet.
This capability makes the facility a strong fit for aerospace, defense, advanced robotics, and semiconductor equipment programs that require tight tolerances, repeatability, and material traceability.
Wire and sinker EDM extend the facility’s capabilities to precision geometries that are difficult to produce with conventional milling, including intricate cavities, thin walls, and hardened materials.
Very few suppliers in the market can execute additive manufacturing and precision CNC machining at a high level under one roof. At Fathom’s Hartland facility, DMLS parts move directly into precision machining workflows, with engineering oversight across the full process.
DMLS produces near-net metal parts with complex internal geometries, excellent tensile strength, and high wear resistance. When those parts also require tight-tolerance external surfaces, threaded features, or precision interfaces, they need to be finished on CNC mills or lathes. Fathom handles both steps without a supplier handoff, eliminating tolerance risk and lead time added by coordinating between vendors.
Typical parts produced through this workflow include structural aerospace components, satellite housings and brackets, thermal management components, lightweight structural frames, and complex manifolds with internal channel features.
The Milwaukee-area facility handles assembly and finishing entirely in-house. Welding capabilities include TIG, MIG, and laser welding. Additionally, heat treatment, surface finishing, and three dedicated paint booths support a wide range of part requirements.
Inspection is performed with a CMM and laser inspection equipment, providing the dimensional verification and documentation that regulated industries require.
With Fathom’s facility near Milwaukee, WI, customers receive a fully manufactured part, not a machined blank that must still be sent elsewhere for finishing.
The breadth of capabilities at Fathom’s Milwaukee-area facility supports programs across high-stakes industries where precision and compliance are non-negotiable.
We work with leading manufacturers in these industries:
The following case studies reflect the caliber of work Fathom delivers across its U.S. facilities, including the Hartland location. Discover what it means to have a manufacturing partner with engineering depth, equipment capacity, and rigorous quality systems behind every build.
We specialize in low-volume, high-mix projects and support customers throughout the full product lifecycle, from design through production. We work closely with engineering and procurement teams to understand requirements, the environment where parts will operate, and the cost, timing, and quality targets the program demands.
Our process begins with a detailed DFM report, but it does not stop there. Our engineers bring decades of experience across additive and subtractive manufacturing, which allows them to identify geometry-specific challenges and resolve them before parts go into production.
This facility handles post-processing, finishing, welding, and inspection entirely in-house. There are no handoffs to external suppliers for surface finishing, heat treatment, or dimensional verification. That integration keeps lead times tight and ensures every step meets the same quality standard.
We operate 57 additive manufacturing machines across five technologies and 34 CNC and EDM machines, including five-axis vertical machining centers capable of handling parts up to 6 feet by 10 feet. The Milwaukee area facility is the largest machine shop in southeastern Wisconsin. The capacity is here, whether a program is in early prototyping or moving into production.
The Hartland facility is the home of Fathom Edgeworks Fathom’s fully managed global sourcing program. For customers facing margin pressure, tariff exposure, or supply chain complexity, Edgeworks provides the lowest fully landed cost backed by U.S.-based engineering and program management support.
Steve Brahm leads Fathom’s Hartland facility as General Manager, bringing decades of hands-on manufacturing leadership across operations, engineering, and supply chain. His background is rooted in complex aerospace and defense programs, and he understands the precision, compliance, and accountability those projects require in practice.
Steve works directly alongside customer engineering and procurement teams to translate technical requirements into practical manufacturing solutions. When a program gets complicated, his team is already inside the problem.
As a Six Sigma Green Belt, Steve applies Lean manufacturing and continuous improvement principles across the facility’s operations, with a focus on quality, delivery, and cost performance.

Fathom’s Hartland facility brings the equipment depth, engineering expertise, and compliance infrastructure that complex programs require. Whether you need 3D printing in Milwaukee, WI, for a rapid prototype, a DMLS component finished to aerospace tolerances, or a manufacturing partner for a full production program, we are ready to get to work.
Fathom’s headquarters is located at 1050 Walnut Ridge Drive in Hartland, Wisconsin, approximately 30 miles west of downtown Milwaukee. The facility is easily accessible from the greater Milwaukee metro area, Waukesha, and surrounding communities.
Yes. We welcome on-site visits from engineers and procurement teams in the Milwaukee area. Meeting in person gives customers the opportunity to tour the floor, see the equipment firsthand, and work through design and process questions directly with our engineering team before a project begins.
For 3D-printed parts, the facility can deliver as fast as the next business day. CNC machining lead times vary depending on part complexity, material, and volume, but local customers benefit from the ability to coordinate directly with the team on-site for time-sensitive programs.
The Hartland facility specializes in low-volume, high-mix projects, which makes it well-suited for companies at any stage, from startups developing their first prototype to established manufacturers managing complex production programs. Program size is less important than technical fit.
The facility is particularly well-aligned with Wisconsin’s aerospace and defense, advanced robotics, and industrial manufacturing sectors. With ITAR registration, AS9100-2016 certification, and NIST 800-171 compliance, it is structured to support the regulated, precision-driven programs common across these industries in the region.
No. Fathom is a nationwide advanced manufacturer with eight U.S. locations and a global sourcing network through Fathom Edgeworks. The Hartland facility serves as the company headquarters, but Fathom’s capabilities span the country, supporting engineers and procurement teams across industries and regions, from early prototyping through full-scale production.
