A new nickel-based additive manufacturing powder, Höganäs Amperprint 0233 Haynes 282, has been launched for Velo3D’s Sapphire 3D printers, with the superalloy designed for high-temperature structural applications.
The powder, produced by Höganäs AB under license from Haynes International, Inc, is designed for high creep strength, thermal stability, weldability not commonly found in other alloys.
Powdered nickel-based superalloys, like Amperprint 0233 Haynes 282, are often used to print parts for use in high-temperature applications due to the alloy’s resistance to cracking and its ability to operate at near-melting-point temperatures. This tolerance allows parts printed with the alloy to be used in vacuum, plasma, and other demanding applications.
Velo3D says the the material is ideal for high-temperature structural applications like energy generation, gas turbines, and space launch vehicles to build parts like ‘heat exchangers, combustors, nozzles, combustion liners, rocket engines, and shrouded impellers’.
“Our goal at Velo3D is to enable engineers to build the parts they want without compromising on the design or quality,” said Velo3D CEO Benny Buller. “Qualifying new powdered metals, like Amperprint 0233 Haynes 282, for use in our end-to-end solution, further expands what’s possible with our additive manufacturing technology.
“Our partners at Höganäs provide materials of the highest quality, and I look forward to seeing what our customers build using this amazing alloy.”
Höganäs is a specialist in metals, with experience in creating powders for additive manufacturing that require consistent spherical shape, tight control on chemistry, and the enhanced ability to flow within an AM system.
“It’s inspiring to see what engineers have been able to build using metal powders from Höganäs and Velo3D’s support-free additive manufacturing process,” said Jerome Stanley, Höganäs director of global sales, customisation technologies.
Stanley explained that the first parts printed using its Amperprint 0233 Haynes 282 powder are “impressive”, and believes customers are only scratching the surface of what is possible with this superalloy. “The powder, combined with Velo3D’s end-to-end solution metal AM solution, is an extremely effective combination for consolidating parts into monolithic structures to eliminate coefficient of thermal expansion in large, high-performance systems,” he said.
The first Sapphire printer utilising the Amperprint 0233 Haynes 282 powder will be operated by Duncan Machine Products, a contract manufacturer based in Oklahoma, USA, which will be the seventh in the company’s fleet of Velo3D Sapphire 3D printers.
