Abstract
A method of three-dimensional printing, comprises: operating a printing head having a nozzle array to dispense a building material formulation, wherein the printing head is directly connected to a cartridge containing the building material formulation, and wherein the printing head comprises a channel conveying a building material formulation received from the cartridge to the nozzle array; discarding the building material formulation from the channel; and connecting a cartridge containing a building material formulation that is different from the discarded building material formulation to the channel.
Claims20
A method of three-dimensional printing, comprising:
- operating a printing head having a nozzle array to dispense a building material formulation, wherein the printing head is directly connected to a cartridge containing the building material formulation, and wherein the printing head comprises a channel conveying a building material formulation received from said cartridge to said nozzle array;
- discarding said building material formulation from said channel;
- and
- connecting a cartridge containing a building material formulation that is different from said discarded building material formulation to said channel.
A three-dimensional printing system, comprising:
- a plurality of cartridges each containing a different building material formulation;
- a printing head having a plurality of nozzle arrays, and being directly connected to said plurality of cartridges, wherein the printing head comprises a manifold with a plurality of channels, each conveying a building material formulation received from a separate cartridge to a separate nozzle array;
- and
- a controller for operating said printing head;
- wherein the three-dimensional printing system is devoid of any printing head which is not directly connected to said plurality of cartridges.
