The Critical Role of Additive Manufacturing for Aerospace Applications:
The Aerospace industry has been integrating DMLS (Direct Metal Laser Sintering) in its structural applications for years. Other industries are now jumping on board with this cutting edge technology (oil and gas, medical, military, auto…). While typical applications revolved around standard objects such as brackets and ducts using investment casting- the future lies with 3D Design-for-Manufacturing. Nozzles, Injectors, Turbine Blades, Wing Spans, Spars, Struts, Entire Jet and Rocket engines all contain 3D production parts. Check out GE’s latest DMLS advancement.
Exciting New Metals for Aerospace: Titanium Ti-6Al-2Sn-4Zr-2Mo (Ti-6-2-4-2)

Titanium (Ti-6Al-2Sn-4Zr-2Mo) has generally been intended for high temperature use in environments up to 538°C (1000°F). Common applications consist of “hot section” gas turbine components such as discs, impellers, turbines, etc. With excellent tensile creep and fatigue properties, Ti 6-2-4-2 is also used for afterburner structures and hit airframe “skin” applications. Not readily available, Ti-6-2-4-2 is possible to convert and print using DMLS. i3D™ specializes in custom DMLS powder development and production.
Titanium is considered difficult to machine or cast. While Titanium for DMLS requires experienced operators, once its risk factors are mastered, it is forgiving and relatively affordable using DMLS. Its characteristics have been compared to those found in 316 Stainless Steel 3D printed parts. Recommended practice includes high coolant flow which aids the offset of the materials for minimal thermal conductivity establishing gradual speeds and relatively high feed rates.
i3D™ works relentlessly to make sure customer requirements are always met and understood. We actively use our manufacturing knowledge for customers’ benefits. Whether it is one part or production volume parts, i3D™’s experienced team is determined to deliver the highest quality part, quickly and accurately.
