Device and method of filling grooves

A deposition system for depositing a printable medium in a groove provided within a surface of a workpiece, the deposition system comprising

• a deposition head including a deposition face;
• and
• a drive unit for providing relative motion between the deposition head and the workpiece in a direction transverse to the surface of the workpiece;
• wherein the deposition head comprises:
• a main body, including at least a first deposition chamber that is at least in part defined by a recess in the main body and that extends to a first orifice in the deposition face between at least two shutter elements;
• and
• a first pressurizing mechanism acting on the first deposition chamber, and configured to in use apply a first working pressure onto the printable medium contained in the first deposition chamber;
• and
• at least a first mount provided to the main body;
• said wherein the at least two shutter elements include a first shutter element comprising a first blade extending from the first mount towards another of the at the least two shutter elements to close the first orifice between terminal ends of the first blade and an other shutter element of the at least two shutter elements in a closed condition, and
• said wherein the first blade is configured to flex in response to an applied first working pressure to at least partly open the first orifice;
• and
• wherein the drive unit is arranged to in use adjust a relative position between the main body and the surface of the workpiece to maintain a flush contact between the surface of the workpiece and the terminal ends of the first blade and the other shutter element while in a flexed condition.
