Well spotted Jaykay. Atm there is only a handful of material that you can use. If part needs postprocessing either by hand or traditional CNC equipment, the only materials that can be used is those that does not “work-harden” during processing. And there is not a whole lot of those. That is why (I suspect) this engine is 100% made out of aluminum (non-functional, demo purposes). Bringing along material properties of specific metal/alloy in the adaptive technology is something that remains a great mystery for many of us here.
Melted steel becomes brittle “as glass” (some grades anyway). Try to process this stuff in a conventional CNC milling machine afterward for fun
Like I said all a little faked but still worth showing. That’s why you see patterns being ‘etched’ instead of being 3D printed for real. Regardless the concept (top secret) is pretty obvious along with Siemens NX showing the laser add-on module performing. In fact I don’t blame them for hiding the true manufacturing methods, I’d possibly do the same thing.
RE this engine; I bet nobody was allowed in-or-near that room when they fired-up. You wouldn’t want to introduce any sort of vibrations when this aluminum thing spins above 30K. At those revolutions there is a whole new centrifugal force, vibration and harmonics taking place (not your average Porsche IMS). Can you imagine the explosion lollll
50% Hollywood and 50% real. Again, just a glimpse. The reality behind this is; what’s coming your way – sooner than you can imagine!
