Inconel 718 exhibits an exceptional thermal resistance, up to 700°C, and high resistance to oxidation and corrosion. It also offers excellent strength, with high yield, tensile and creep-rupture properties. 3D-printed Inconel retains strength over a wide temperature range, making IN718 an attractive choice for extreme environments, whether in high-temperature applications like turbines and engine parts or low-temperature applications like cryogenic environments. Inconel is ideal for the aerospace and automotive industries, with common applications including ductwork, valves and heat exchangers.

Actual values may vary with build condition

Strong tensions, due to part geometry, may cause distortion in the part which may lead to greater deviation. Values for surface roughness depending on orientation or surface. Downward-facing surfaces and surfaces with support will be rougher.

Values represent stress relief heat treated status. No aging.

How Does Metal 3D Printing Work?

Metal 3D Printing is a laser-based technology that uses powdered metals. Similar to Laser Sintering, a high-powered laser selectively binds together particles on the powder bed while the machine distributes even layers of metallic powder. Support structures are automatically generated and built simultaneously in the same material, and are later manually removed. Once complete, the part undergoes heat treatment.
