Aerospace Additive Manufacturing Tooling: What East/West Industries Shows

Aerospace tooling capacity is the real lesson

The East/West Industries Fortus 450mc FDM case study is useful because it shows a specific aerospace supplier problem: customer-part machining and workholding-tool production were competing for the same CNC resources. For suppliers facing similar tooling pressure, the case gives a practical way to think about additive manufacturing for fixtures, soft jaws, and production aids.

The approved case study describes East/West Industries as a manufacturer of products that help save aircrew lives for aerospace customers including Boeing, Lockheed Martin, and Northrop Grumman. As demand grew, its CNC machine shop became a constraint because the same machining resources used for customer parts were also being used to make workholding tools.

The case should still be read with discipline. It is strongest as an aerospace tooling and production-aid lesson, not as a promise that every supplier will see the same result or that additive manufacturing bypasses aerospace release requirements.

Workholding was competing with customer-part machining

The operating issue was practical. More work required more fixtures, more programming, more machine time, and more skilled operators. East/West could have considered another CNC machine, but the case study notes that CNC equipment is space and capital intensive and that experienced operators can be difficult to find.

The immediate opportunity was not decorative prototyping. It was production support: printed workholding fixtures and soft jaws that could reduce pressure on CNC equipment and allow those machines to focus on value-added parts.

For aerospace suppliers, this is often where additive manufacturing first earns attention. Tooling, fixtures, soft jaws, surrogate parts, concept models, replacement forming tools, and manufacturing aids can create a clearer first use case than a direct move into flight or safety-critical components.

Why Fortus 450mc and FDM Nylon 12CF fit the use case

The case study states that East/West selected a Stratasys Fortus 450mc with broader capacity and material options, including carbon fiber FDM Nylon 12CF. The choice was tied to the workholding applications the team wanted to address, not to additive manufacturing as a general technology preference.

That is the right way to frame material and process selection. FDM may be suitable for selected tooling, fixtures, and production aids where the geometry, load, temperature exposure, surface requirement, clamping behavior, and expected life fit the application. FDM Nylon 12CF may be relevant where a stiff carbon-filled polymer route is appropriate, but the material name alone does not prove suitability.

Aerospace suppliers should connect each printed tool to its function. A soft jaw, forming aid, assembly fixture, drill guide, inspection aid, or surrogate part each needs its own acceptance logic. Some can be managed through internal manufacturing controls. Others may require stronger engineering, quality, or customer review before use.

Printed tooling still needs inspection and release rules

Production aids can influence part quality even when they are not delivered to the aircraft or end customer. A printed fixture that locates a component, holds a machining operation, supports forming, or guides assembly can affect dimensional results, repeatability, operator behavior, and inspection outcomes.

The level of control should match the tool. Useful checks may include dimensional inspection, fit checks against the mating part or machine setup, surface review, clamping or load-path review, revision control, operator instructions, and a record of who released the tool for shop-floor use.

This is where aerospace additive manufacturing can lose discipline. A tool that works once still needs a repeatable data package if it will be used again. The package should define the file, material route, printer route, build orientation where relevant, post-processing, inspection method, revision status, and restrictions on use.

The reported numbers belong to this case

The East/West Industries PDF supports several specific outcome claims. It states that 3D printed workholding fixtures reduced tool production time by two days on average, cut tool cost by 50 percent, and increased overall product readiness by two weeks. It also states that soft jaw tooling could be printed overnight and put into operation the following day.

The same PDF describes a damaged sheet metal forming tool that East/West replaced using carbon fiber FDM Nylon 12CF. Within two days, the team had a new tool that successfully handled the job. That is a useful example of additive manufacturing applied to a shop-floor tooling problem, but it should not be generalized into a fixed turnaround time for every aerospace supplier or every tooling application.

The current article previously used an unsupported percentage reduction. That exact figure is not supported by the PDF text inspected for this rewrite, so it should not remain. A defensible reading is narrower: East/West reported measurable tooling improvements for specific FDM workholding and forming-tool applications after selecting the Fortus 450mc and FDM Nylon 12CF around a defined CNC bottleneck.

Where aerospace suppliers can apply the lesson

The East/West case points toward a practical screening method. Use the shop-floor constraint as the baseline, then identify tools and aids that are consuming CNC capacity, waiting on external suppliers, or slowing production support work. Classify each item by function, risk, material requirement, load, tolerance, inspection need, and approval boundary.

Good early candidates are often internal tools: workholding fixtures, soft jaws, assembly aids, forming supports, check fixtures, concept models, surrogate parts, and limited-use manufacturing aids. These are still engineering items. They should not be treated as casual prints, especially in aerospace environments where tooling can affect the delivered product.

Conventional machining, purchased tooling, or an approved supplier may remain the better route when the tool requires tight tolerance, high surface quality, known metal behavior, heat resistance, long service life, customer approval, or a documented qualification path that the printed route cannot support.

D2M support for aerospace tooling decisions

D2M can help aerospace and industrial suppliers assess where additive manufacturing fits tooling and production-support work. The work can include application screening, material and process selection, fixture design review, build-route definition, inspection planning, documentation mapping, and business-case comparison against the current route.

That support does not replace customer approval, aerospace certification, material qualification, production release, or a supplier quality system. The value is in making the decision record clearer before a supplier moves work from a machine shop, tooling supplier, or conventional route into additive manufacturing.

For many suppliers, the best first output is a ranked tooling list. It should show which fixtures and aids are suitable for FDM, which need more engineering data, which should remain machined, and what inspection or release steps are required before use on the shop floor.
