Hans Peter of Embryonic.dk has been working on a Laser cutter project and wrote a detailed explanation on his blog describing the build:
Having seen the crazy-fast development of the printers during the time I’ve had mine, I can clearly see that my printer is not the fastest or the most precise in the league anymore. Most of the newer printers use some kind of lasercut frame or piece somewhere. While I can get to a laser cutter, it takes a lot of time and I’m not guaranteed that it’s available when I need it. so therefore – I want my own. Commercial cutters cost around 45kDKR and up, so that’s a no. Instead, I will be building one on my own.
