Simply put, a Robocutter is a printer sized device that automatically cuts & scores papercraft models! Some of our "Print, Build, Play!" products include support for a special file format known as GSD or STUDIO files (we currently support CraftRobo & Silhouette SD automated cutting machines). GSD & STUDIO files open with a program known as “ROBO Master” or “Silhoutte Studio” which tells the cutting machine where to automatically cut and score on a given page.
