ExtendedPrinter (aka PrintARface) is an AR application for the Hololens for learning more about 3d printing and to control a real 3d printer. This application is a prototype for new AR human machine interfaces.
The application is still under development. It is currently being developed for the Lulzbot TAZ6. Support for more printers is planned.
Have look at this video. It is showing the basic functionality: https://vimeo.com/343709587
Research is still ongoing.
