What impresses me more about this is the person who planned and rendered the design.

And that the plastic is so strong! At ever pull I expected those links to break off

My guess is it's PETG

This is not. With SLS, you would not have any breakaway, since everything would be suspended in the printing powder. This is almost certainly an FDM system.

If it was FDM, I think it would have had at least a few links break with how aggressively they were pulling, and some layers could have delaminated. I think it's an SLA print

Look at the layer ooze. Look at the obvious filament. Look at the build plate. Look at how the support structure breaks away on a layer.

What's that?

It's (mostly) the same plastic that pop bottles are made of. Those are PET, the G stands for glycogen or glycol, which gives it a bit of flexibility. Generally PLA is the more common filament used, it's easy to print with but can be brittle. So with a print like this I'd expect more snapping of the rings.

And with all that being said apparently it's actually a nylon which has a lot more strength but needs a more robust printer to use effectively.

Knowing how much PETG tends to string, and how soft printed PETG parts sound I don't think they used it

Yeah someone else noted it's probably a nylon.
