Additive Manufacturing for Firearms

Additive Manufacturing Helps Oregon Firearms Industry Stay Innovative

With big game hunting season winding down in Oregon, it seems appropriate to give a nod to our friends in the firearms industry. Oregon has a long and rich history in firearm accessory manufacturing. Its premier manufacturers epitomize innovation and quality – think Warne Scope Mounts, Nosler, Leupold, and Grovtec. These companies were born from Northwest outdoorsmen’s desire for quality products with superior performance. They’ve become household names today because of their focus and commitment to innovation.

Additive manufacturing, or 3D printing, is helping Oregon’s firearm industry stay a step ahead of its competition. Complex designs that are expensive or even impossible to traditionally manufacture can be 3D printed in metal using Direct Metal Laser Sintering (DMLS) offered by i3D MFG™ and other similar service bureaus. Custom part builds, rapid market launches, and small batch production are all cost effective mean of production using 3D manufacturing. Unlike previous 3D print technologies, DMLS does not use binding agents, therefore, parts near 100% density, and are comparable to machined and high quality cast parts. In fact, this past summer both the FBI and the USSOC commenced in firearms projects using DMLS.

Additive Manufacturing benefits for Firearms

Latticed geometries, conformal cooling lines, organic channels, and single part production of multiple part assemblies are common 3D design features. Since 3D manufacturing is a no-waste process, exotic metals offering superior strength and heat properties are cost effective. Titanium, Inconel, and Steel are the most widely produced DMLS metals in the firearms industry. Lead times with 3D printing allow firearm accessory manufacturers to reduce R&D and market launch to weeks or months compared to months and years. Multiple versions of a design can be 3D printed in the same build, allowing R&D version testing or custom production in days.

i3D™ is proud to be innovating along with Oregon’s industry leaders. Oregon’s proud tradition of recreational firearms and firearm accessory manufacturing will continue to grow and beat its competitive because of their forward thinking and adoption of next generation technology in product development. We hope all the hunters out there had a successful season!

Additive Manufacturing for Aerospace

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)

Chemistry Data :

Aluminum 5.5 – 6.5
Carbon 0.08 max
Hydrogen 0.0125 max
Iron 0.25 max
Molybdenum 1.75 – 2.25
Nitrogen 0.05 max
Oxygen 0.12 max
Silicon 0.1 max
Tin 1.75 – 2.25
Titanium Balance
Zirconium 3.5 – 4.5


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.
