Protolabs, the world’s fastest digital manufacturing source for custom prototypes and low-volume production parts, has announced the addition of Inconel 718 to its growing list of Direct Metal Laser Sintering (DMLS) materials. The addition further establishes Protolabs’ reputation within the aerospace sector for having a highly impressive range of metals available for rapid prototyping and functional end-use parts with complex geometries.
Due to the high strength and corrosion resistant properties of the material, along with its ability to be used at extreme temperatures, Inconel 718 is a proven superalloy in the development of turbojet engines for aircraft, among a variety of other applications.
As a nickel-based heat resistant alloy, Inconel 718 can be used at temperatures between −252 °C and 704 °C. Its high-temperature strength is derived from its ability to create a thick, stable passivating oxide layer at high temperatures, protecting the material from further attack. Inconel also has good tensile, fatigue, creep and rupture strength.
