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

  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-are-the-problems-with-laser-cutting-of-aluminium-and-how-do-i-overcome-them 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.
