Many moons ago, we posted about the Facadeprinter citing some of its basic early paintball-blasted output.
Since then, the device has apparently undergone some major refinements, now in its second prototype -
The printer is equipped with an industrial PC which is running the specially programmed printing software. The machine is operated by touchscreen. Artworks can be loaded from USB-devices in the file format SVG. With an integrated camera photos of the printing area can be taken and overlayered with a printing preview. This way position and scaling can be adjusted optimally on site. The distance to the wall is measured by infrared-meter and entered manually. The printing software calculates the driving coordinates regarding both the perspective and the ballistic distortion.
