Wait... That bolt or bolts (Jesus Nut) are usually 4340/300M steel and sometimes titanium, depending on the helicopter. Someone who knows or does 3D printing, can you actually 3D print these to spec?

3D print no, but you could 3D CNC machine it. Probably would still not have the same strength as drop-forged though, so the joke still ...sorta... lands.

You can 3d print with other materials like concrete and metal. Can you make a helicopter rotor to spec? Highly doubt it and wouldn’t get in one that was going to try.

There is a 3d printing process with titanium (and aluminum) called sintering, which _may_ create strong enough parts in the future. To my knowledge, the ones that exist now a) only make small things and b) the small-things-sintering printer will set you back ~$750k

I’m sure the prices will continue to come down and the tech will keep getting better. Engineers find some incredible geometry that improves strength and other cool properties so it’ll be interesting to see where it goes.There is a 3d printing process with titanium (and aluminum) called sintering, which _may_ create strong enough parts in the future.

This one here prints all kinds of metal, looks fairly large , and is only a quarter mil $.

Your image is from the actual wiki page from the "jesus nut".

If you think people aren't stupid:
Plane crashed after 3D-printed part collapsed
Aircraft crashed in Gloucestershire after 3D-printed part collapsed
The aircraft was completely destroyed after a spare part bought at an air show in America collapsed.

"Robinson helicopters, particularly the R44 and R22 models, are popular but considered dangerous due to their design. Crashes often involve rotor blade separation, slicing through the cockpit and tail boom, and post-crash fires, even after low-impact events. From 2006–2016, the R44 was involved in more fatal crashes in the US than any other civilian helicopter."
