Abstract
There is disclosed an ink composition for three dimensional (3D) printing. The ink composition comprises: a liquid dispersion of tungsten carbide (WC) particles and cobalt (Co) particles, and, a carrier vehicle for the dispersion of tungsten carbide particles and the dispersion of cobalt particles. The ink composition is of a viscosity usable with ink jet print heads for 3D printing.

1-21. (canceled)
A method for manufacturing a three-dimensional object, the method comprising:
- providing an ink composition, wherein the ink composition includes a carrier vehicle, tungsten carbide particles, and cobalt particles;
- dispensing the ink composition from a print head to form a three-dimensional object using an additive process in which successive layers of the ink composition are laid down;
- exposing the dispensed ink to heat up to a first temperature sufficient to evaporate the carrier vehicle;
- and
- exposing the dispensed ink to heat up to a second temperature sufficient to melt the cobalt particles.
