GKN Aerospace Use Stratasys AM to Reduce Tool Production Time

GKN Aerospace is improving production times and removing design constraints for multiple tooling applications since integrating Stratasys additive manufacturing at its Filton manufacturing site in the UK.

GKN serves over 90 percent of the world’s aircraft and engine manufacturers with aerostructures, engine systems and technologies.

According to Tim Hope, Additive Manufacturing Center Manager, at GKN Aerospace, the company decided to invest in the Stratasys F900 Production 3D Printer in a bid to cut lead times for production-line tools, and to create complex parts, impossible to make with traditional manufacturing methods.

Traditionally, the lead-time required to produce a metal or plastic replacement tool is several weeks. Now, with the ability to use an in-house production 3D printer to do the same job, the replacement burden has been removed and the responsiveness to manufacturing requirements improved.

“We can now cost-effectively produce tools for our operators within three hours,” Hope explains. “This saves critical production time, and by printing in engineering-grade thermoplastics, we can produce 3D printed tools with repeatable, predictable quality every time. All while matching the quality of a traditionally-produced tool, and reducing the costs and concessions compared to equivalent metallic tooling.”

While GKN Aerospace is using a standard thermoplastic today, it is experimenting with Stratasys’ high-strength, heat-resistant ULTEM 1010 Resin material for these applications.

Customized, complex tools that were previously impossible to make

In addition, GKN Aerospace is reporting unprecedented levels of design freedom since investing in the Stratasys F900 into its operations.

In addition to design freedom benefits, GKN Aerospace has also seen a 40 percent decrease in material waste.

To the future

Hope anticipates a greater move towards the use of FDM additive manufacturing to produce high-value, flight-critical, end-use composite parts.

He says, “GKN Aerospace’s product range is vast, and we see large-scale FDM and carbon-reinforced parts as the future of additive manufacturing in aerospace. By using Stratasys additive manufacturing for tooling, we are harnessing a machine that offers us the freedom to produce unique and complex tools of any size, with the build quality to match any manufacturing requirement. All while simultaneously preparing ourselves for the future.”
