Largest laser cutting machine

The largest laser cutting machine has a total area of 37.05 m² (398.80 ft²), achieved by Daniel Black in collaboration with Zoe Laughlin and Olivia Clemence (all UK), as measured at the Institute of Making, University College London, London, UK, on 2 October 2014.

The laser outputs light at a wavelength of 445 nm which allows it to etch and cut many materials, and features a custom-made heatsink system to allow it to operate for long periods of time without overheating.
