Robot for large-format, three dimensional digital printing on a fixed surface and printing method involving at least one such robot

Abstract

The invention relates to a robot for large-format, three-dimensional printing on a fixed surface, using five powered spindles. The inventive robot comprises an inkjet printing block, means for moving and orienting said printing assembly along several axes, at least one unit for controlling said means and a device for drying the ink sprayed onto the surface. According to the invention, the aforementioned movement and orientation means comprise: a support having three degrees of freedom in translation, which is used to position the printing assembly by enabling translational movements along horizontal, vertical and depth axes; and a wrist having two degrees of freedom in rotation, which is used to position and orient the printing assembly by enabling same to rotate in relation to two perpendicular axes. The invention also relates to a method of using said robot.
