Methods and systems for printing 3d object by inkjet

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

• supplying ink to a printing head having a plurality of nozzles, wherein the ink includes at least carrier liquid, particles, and dispersant;
• dispensing the ink from the plurality of nozzles to form a first layer;
• heating the first layer to a temperature below the burn off temperature of the dispersant to evaporate the carrier liquid;
• and
• repeatedly dispensing and heating additional layers above the first layer until a three-dimensional object is constructed.

An additive manufacturing system for printing a three-dimensional object, the system comprising:

• a printing head with a plurality of nozzles configured to dispense ink including at least carrier liquid, particles, and dispersant to form a first layer;
• an energy source configured to supply heat to the first layer to a temperature below a burn off temperature of the dispersant to evaporate the carrier liquid;
• and
• a processor configured to instruct the printing head and the energy source to repeatedly dispense and heat additional layers above the first layer until a three-dimensional object is constructed.

A three-dimensional object, manufactured using an additive manufacturing process comprising:
