The pride of company boss Sam O'Leary is in the hermetically sealed development hall: The NXG XII 600 - a 3-D printing machine almost the size of a 7.5-ton truck, equipped with twelve separate lasers, each with one Power of up to 1000 watts. When O'Leary talks about his brand new machine, he raves: “It's twenty times faster than any conventional single laser system and five times faster than the best quad laser machines to date,” explains the Briton. But what is even more important to him is what the machine is capable of.
