Nozzle and system for three-dimensional ink printing

A system comprising:

• a nozzle for a three-dimensional, 3D, ink printer, wherein the nozzle comprises:
• a channel configured to guide ink through the nozzle, and
• an output portion coupled to the channel, wherein the output portion is configured to output the ink,
• wherein the output portion comprises an elongated output channel configured to output the ink at different locations along a length of the elongated output channel simultaneously;
• and
• a mold;
• wherein the nozzle is configured to output ink onto the mold.

A method for printing a three-dimensional, 3D, object, the method comprising:

• providing a mold and a nozzle, wherein the nozzle comprises an elongated output channel configured to output ink at different locations along a length of the elongated output channel simultaneously, and wherein a shape of the elongated output channel conforms to a shape of the mold;
• rotating, via a first motor, the mold;
• and
• outputting, via an output portion of the nozzle, the ink onto a first part of the mold, wherein the output portion of the nozzle comprises at least a section of the elongated output channel.
