The present disclosure pertains to a deposition system, a method and use of such system for filling a groove provided into surface of a workpiece with a printable medium, in particular a highly viscous paste. The system includes a deposition head that includes a first deposition chamber that extends to a first orifice. The orifice is reversibly closed off between at least two shutter elements. In some embodiments the system is a dual chamber system, each chamber having a reversible closable orifice. The system is arranged to maintain a flush physical relationship between the workpiece and the terminal ends of the shutter elements, so as to, upon application of a working pressure, fill the groove.
