We’re passionate about innovation at Velo3D, and that passion extends to the qualified materials supported by our end-to-end metal additive manufacturing (AM) solution.
Of course, it remains our goal to help engineers leverage our technology to overcome the many challenges they face, so it’s always exciting when we welcome a new entry to our burgeoning portfolio of qualified materials.
The newest material, Amperprint® 0233 Haynes® 282®, is one that we are especially excited to talk about.
Applications and material properties
As a world-leader in material development, Haynes International has decades of experience developing high-quality metal alloys.
While the alloy itself is developed by Haynes International, the company partners with other organizations to produce the alloy in powder form. In the case of Amperprint® 0233 Haynes® 282®, the powder was developed by Höganäs AB, a leading manufacturer of metal powders for powder metallurgy under license from Haynes International, Inc.
Ideal for high temperature applications such as gas turbine and power/process industry parts, Amperprint® 0233 Haynes® 282® is classified as a precipitation-hardenable nickel-based super alloy and is known for its excellent tensile strength when subjected to extreme pressure and heat.
Even at high temperatures, the alloy exhibits excellent grip strength and thermal stability, allowing it to retain its shape and strength properties.
The alloy’s unique set of properties makes it especially suited to welding and fabrication. These characteristics also make it ideal for Laser Powder Bed Fusion (LPBF), the AM process employed the Velo3D end-to-end solution.
Its weldability means that it largely avoids the challenges faced with other nickel alloys, specifically issues related to cracking and hardening.
For these reasons, the material has become a leading candidate for emerging technology applications and readily adopted by major gas turbine manufacturers. The above properties also make it valued and sought after for use with critical applications in the aerospace, defense, and petrochemical industries.
Design freedom, quality, and efficiency are the driving forces behind our end-to-end Metal AM solution. In support of those driving forces, the entire Velo3D family of Sapphire printers use the same portfolio of metal alloys to consistently produce the highest quality parts.
The performance criteria for our powder supply chain are rigorous and not only governed by our partner agreements but by our own quality qualification process and the specific print recipes we build for each alloy used in our underlying Intelligent Fusion® manufacturing process.
All our materials, process parameters, and family of Velo3D printers are optimally aligned to reliably and repeatably provide the desired part properties for production of your unique parts. This selection of alloys enables a wide range of applications spanning Space, Aviation, Energy and Defense.
The combination of quality development and the Velo3D solution mean that Amperprint® 0233 Haynes® 282® is easy to work with, allowing designers and engineers true design freedom, a broader set of parameters to work within—all while getting the desired outcome they require.
At Velo3D, we’ve earned a reputation for helping companies manufacture their most challenging and mission critical parts, with unique performance requirements, performance capabilities and complex geometries, such a low angles, thin walls, and extensive internal channels—and many with little to no supports needed.
So, the combination of what you can do with the Velo3D system and material properties of the alloy make it a good fit, especially if you want to push the boundaries of innovation and performance.
Velo3D-printed combustor liner
In the world of metal AM seeing is believing. The image below is that of a Velo3D-printed combustor liner, which is a good example of what can be achieved with Velo3D and Amperprint® 0233 Haynes® 282® combustor liner was printed using a Velo3D Sapphire® printer and would be incorporated into the combustion chamber of a gas turbine engine. Fuel is sprayed into liner, allowing both combustion air and cooling air flow to pass through.
The above part features a thin wall structure (roughly 1.4 mm around), with 23,000 individual holes— consisting of 3,000 1mm diameter holes around the lower portion and 20,000 .5mm diameter holes at the top and inside—for optimized air to fuel ratios.
The combustor liner measures 29mm in diameter and 225mm in height, with 128 0.8mm swirling mixture blades built internal to the nozzle at the bottom.
Diving deeper into its material properties reinforces Amperprint® 0233 Haynes® 282® and its use in additive manufacturing and high-stress applications, thanks to a rupture strength at temperatures of up to 1290 °F (980 °C). Amperprint® 0233 Haynes® 282® also possesses a unique combination of creep strength, thermal stability, weldability, and fabricability.
More materials are on the way
At Velo3D, we’ve taken a laser-focused approach to material qualification. While conventional machines may boast a greater variety of materials, many of those materials simply don’t align with the cost and/or the application of printing additively with that material.
Instead, we’ve simplified our portfolio of materials to those that are ideal for printing parts where fluids flow through, or ones that exchange heat. And because of that focus, we’ve made it easier to identify the best-fitting materials to qualify, such as Amperprint® 0233 Haynes® 282®.
Of course, we continue to qualify the highest quality alloys with the best performance for our end-to-end metal AM solution. This is especially true for the most mission-critical applications in Space, Aviation, Energy, and Defense.
Our team of materials and metallurgy experts continuously qualify new materials on our Sapphire® family of printers based on customer requirements and feedback. Should you require different alloys—simply contact us.
