A three-dimensional (3D) printer includes a selective solidification module to selectively solidify portions of successive layers of a build material on a build platform. The 3D printer also includes a cartridge receiver to hold a removable material cartridge that accepts material from the 3D printer and makes material available to the 3D printer for printing of the 3D object.

Three-dimensional printer

Apparatus and methods are provided. A supply of ink within a flexible bag is located apart from a printer. A fluid conduit couples the supply of ink to the printer by way of a connecting head. The connecting head includes a pump driven by a mechanical actuator of the printer. Operation of the pump causes a flow of ink from the flexible bag to a printhead of the printer. Pump failure is detected and interpreted as an out-of-ink condition, and user notification and/or cessation of printing operations are automatically performed.

Remote ink supply

A solution is provided that includes a non-aqueous organic solvent within which a solute has been dissolved. A thermal-fluid ejection mechanism is provided that has fluid-ejection nozzles and that is capable of thermally ejecting the solution. A device medium is provided that has a three-dimensional surface on which the solution is to be ejected. The fluid-ejection nozzles of the thermal fluid-ejection mechanism are controlled to eject the solution onto the three-dimensional surface of the device medium in accordance with a desired pattern.
