Lasers. I think their technique is top-secret, because I don't see lights-through-metal on many other products.

Aren't lasers a standard method for cutting 2d work?

Perhaps they are using the same technique, but in a 3d setup.

Edit: found an interesting link: https://www.twi-global.com/technical-knowledge/faqs/faq-what...

> The 'aluminium cutting system' which most modern equipment uses is actually a way of protecting the laser rather than an innovative technique for cutting.

Cool, I figured someone must have reported on it, but couldn't find that.
