To test the durability and potential of 3D printed nickel alloy printed turbine blades, we've had some examples made for the Orenda11/14 turbojet engine.
These are the first stage blades, and will be running at about 1200 degrees F, and 7800 rpm.
We have a few of these engines in storage, so it is the simplest setup to use for testing purposes.
Let's hear your judgements, criticisms, and predictions.
