Materials reference
Inconel 718 (EOS IN718)
What is it?
Inconel 718 (EOS IN718) is a metal alloy selected for particular strength, temperature, weight or manufacturing needs.
Why would someone print it?
Printing may help create complex shapes or low-volume parts, but the complete finishing and inspection route still matters.
What should a beginner know?
- Confirm the exact machine, material settings and acceptance requirements.
- A material listing does not by itself qualify a production part.
What happens after printing?
Printed parts may need heat treatment, support removal, machining, finishing and inspection before they are accepted.
What is an alloy?
What does this mean? An alloy is a defined metal composition. Why does it matter? Composition, process settings and post-processing affect the finished part.
