The present invention discloses a silicon wafer printer for double half-cell printing, comprising a work platform, a turntable assembly, a front-end conveyor, a left calibration module, and a right calibration module. A calibration vision camera is mounted above the front-end conveyor's end. The left linear module connects to a left motor module and then a left suction module. The right linear module connects to a right motor module, two calibration cylinders, calibration bearings, and a right suction module. It uses visual positioning to determine double half-cells' position/angle, adjusts the right half-cell with the left as reference, shortens alignment time, adopts single-head front-to-back printing and a smaller indexing disc, boosting turntable printing efficiency.

Tooling for supporting workpieces during a printing operation, comprises a support tower comprising a base and a head, the head being positioned vertically above the base in use, the head being relatively moveable with respect to the base in a horizontal plane in use, the head having first and second support surfaces located at an upper end thereof, each of the first and second support surfaces being adapted to support a respective workpiece thereon, wherein the first support surface is relatively moveable with respect to the second support surface in a vertical direction in use between a printing configuration in which the first and second support surfaces are substantially coplanar in the horizontal plane, and a pre-printing configuration in which the first and second support surfaces are spaced in the vertical direction.
