Line Card
AGF Defcom is a U.S.-based DMLS additive metal manufacturer purpose-built for the firearms and defense industries, based in Imperial, Pennsylvania. The facility was designed from the ground up to support every step of the suppressor manufacturing process — from DfAM design review through DMLS build, stress relief, heat treat, 5-axis CNC finish machining, and final inspection — giving suppressor OEMs a true domestic one-stop shop for additive suppressor production.
The shop runs more than 20 EOS DMLS printers including M400 and M300 systems for production and M290 for prototypes, with build volumes up to 400mm x 400mm x 400mm. Alloys include 17-4 PH, Ti-6Al-4V, Inconel 625, Inconel 718, and Haynes alloys. Two vacuum furnaces support in-house stress relief and heat treatment. 5-axis CNC machining handles critical bores, threads, and sealing faces to print after the build.
Programs range from prototype suppressors and first articles through bridge and full production runs. AGF Defcom holds FFL and SOT licenses and is ITAR registered, making them one of the few DMLS manufacturers in the U.S. fully equipped to serve NFA-regulated suppressor programs from a single facility.

DfAM Review
Design-for-additive review before any build begins — catching printability issues, orienting for best properties, and locking tolerance strategy upfront.
- Wall thickness, internal channels, supports, and build orientation review
- Alloy selection: 17-4 PH, Ti-6Al-4V, Inconel 625, Inconel 718, Haynes alloys
- Tolerance strategy: as-printed surfaces versus post-machined critical features
- Suppressor-specific: baffle stack geometry, bore alignment, sealing surface strategy
Build and Depowder
20-plus EOS DMLS printers running production and prototype builds with full depowdering and EDM part removal in-house.
- EOS M400 and M300 for production builds (up to 400mm x 400mm x 400mm)
- EOS M290 for prototypes and first articles (250mm x 250mm x 325mm)
- Layer thickness 20 to 80 µm depending on alloy and feature mix
- Full in-house depowdering and EDM part removal from build plate
Heat Treat and Stress Relief
Two in-house vacuum furnaces for stress relief and heat treatment — no outside processing delays on critical thermal cycles.
- 2 vacuum furnaces for stress relief and heat treatment
- Stress relief per alloy and geometry to prevent distortion
- Heat treat to strength and hardness targets per program requirements
- Media blast and tumble prep for surface conditioning before CNC
5-Axis CNC Finish and Inspect
5-axis CNC machining of critical bores, threads, and sealing faces after the build — delivering parts complete to print with full documentation.
- Critical bores, threads, and sealing faces machined to print tolerance
- 5-axis contouring with fixturing for thin-wall and suppressor tube features
- Final inspection and documentation (FAI and Certificate of Compliance as required)
- Suppressor-specific: end cap threads, bore concentricity, tube OD/ID finish

A great fit for
- Suppressor OEMs needing a domestic DMLS manufacturer with FFL, SOT, and ITAR compliance under one roof
- Defense and firearms programs requiring complex internal geometries, thin walls, or integrated features only achievable with additive
- Programs needing DfAM through build through heat treat through 5-axis CNC finish all managed in-house
- Prototype first articles through bridge and production runs in titanium, Inconel, 17-4 PH, or other advanced alloys
- Industrial and energy programs requiring production-grade DMLS with full traceability and documentation
×
Not the right fit for
- Simple turned or milled components better served by CNC bar stock machining
- Programs requiring non-domestic or offshore manufacturing
- Very large structural weldments or castings outside the DMLS build envelope
- Same-day or next-day emergency builds
Design for Additive Manufacturing
What We Look At
- Geometry and walls — minimum wall and feature sizes, fillets, overhangs, ribs, and self-supporting angles
- Supports and orientation — fewest supports, easy removal, best surface on critical faces, shortest build height
- Channels and holes — printable diameters, powder escape holes, straight versus helical channels, post-reaming plan
- Tolerance plan — what stays as-printed versus what gets CNC finished (bores, threads, sealing faces, datums)
- Material and heat treat — 17-4 PH, Ti-6Al-4V, Inconel 625, Inconel 718, Haynes alloy selection, stress relief and HIP needs, final target properties
- Cost drivers — part height, support volume, nesting efficiency, cycle time, post-ops count
Fast Rules of Thumb
- Aim for 45 degrees or greater self-supporting angles where possible
- Keep minimum walls approximately 0.5 to 0.8 mm — thicker for tall spans
- Provide powder escape paths for all internal cavities
- Call out machined features (diameters, threads, sealing faces) explicitly on the print
- Shorter build height means lower cost and faster cycle when orientation allows
What You Get from a DfAM Review
- Recommended build orientation and support strategy with critical-face protection
- Feature recommendations (radii, wall and slot sizes, channel diameters) to ensure reliable printing
- A clear post-process map: stress relief or HIP — blast — 5-axis CNC — inspect (FAI and Certificate of Compliance)

Outside Process Capabilities
AGF Defcom handles the full process in-house to keep paperwork and lead time minimal. The only step sent outside is final coating such as Cerakote, and a local source is available if needed. Most customers prefer to visually inspect parts before coating, so requests for this step are uncommon.
