Metal (LPBF)

Inconel 3D printing

Inconel 718 is a nickel superalloy for parts that work at high temperature; it is 3D printed by powder-bed fusion (LPBF). We offer Inconel 3D printing, quoted job by job.

What it is for

Inconel 718 is used for parts that work at high temperature under load and in corrosive environments: turbine and turbocharger components, exhaust manifolds, nozzles, chambers and burners, parts for chemical plants and for bench tests. It keeps its mechanical strength and resists oxidation at temperatures at which steels and titanium give way.

It is hard to machine: powder-bed printing cuts down the machining and allows internal cooling channels. It does not pay if the temperature does not call for it: for corrosion at room temperature stainless steel is enough, for low weight titanium.

Typical values from the makers' data sheets, measured on specimens under the conditions stated. They are not guaranteed design values: for a critical application ask us for a test on your part.

Design limits

Build volume: 400 × 400 × 400 mm
Minimum feature: 0.75 mm
Dimensional tolerance: ±0.2% (minimum ±0.1–0.2 mm)

These are the limits of the process, the same for every variant unless stated. For critical dimensions, talk to us before printing.

Which variant to choose

In Inconel we offer the 718 alloy. Choose stainless steel if the part works at moderate temperature.

FAQ

Frequently asked questions

The process data sheet states heat resistance up to 700 °C, without specifying load and duration. It is an indication, not a design value: for parts loaded in heat, creep and thermal fatigue are what count. Tell us the temperature, the load and the length of the cycle.

The data sheet reports a tensile strength of 1505 MPa in XY and 1375 MPa in Z, a yield strength of 1240 and 1145 MPa, an elongation at break of 12% and 17% and a hardness of 47 HRC. The sheet does not state the condition of the material, as built or heat treated, nor the test standard.

Yes, but it is a tough alloy that work-hardens: it machines slowly and wears the tools. It pays to design the part so that it comes out of the print close to its final shape and to leave stock only on seats, seals and threads. Mark the surfaces to be machined on the drawing.
