Abstract
A shear thinning build material slurry includes metallic or ceramic particles having a particle size up to about 20 μm; a hydrocolloid present in an amount ranging from about 0.05 percent by volume to less than 0.5 percent by volume of the shear thinning build material slurry; and water. The build material slurry is a ready-to-use three-dimensional (3D) printing build material.
Claims16
A shear thinning build material slurry, comprising:
- a build material consisting of ceramic particles having a particle size ranging from about 1 μm to about 20 μm;
- a hydrocolloid present in an amount ranging from about 0.05 percent by volume to less than 0.5 percent by volume of the shear thinning build material slurry;
- and
- water;
- wherein the build material slurry is a ready-to-use three-dimensional (3D) printing build material.

A three-dimensional printing kit, comprising:
- a shear thinning build material slurry, including:
- a build material consisting of ceramic particles having a particle size ranging from about 1 μm to about 20 μm;
- a hydrocolloid present in an amount ranging from about 0.05 percent by volume to less than 0.5 percent by volume of the shear thinning build material slurry;

4 more elements
A method for three-dimensional (3D) printing, comprising:
- exposing a build material slurry to a shear rate greater than about 100 s−1, thereby reducing a viscosity of the build material slurry to less than 10 Pa·s−1, the build material slurry comprising i) a build material consisting of ceramic particles, ii) a hydrocolloid, and iii) water;
- while the viscosity is reduced, applying the build material slurry to form a slurry layer;
- evaporating at least some of the water from the slurry layer to form a build material layer;
- and
- selectively applying a patterning fluid on at least a portion of the build material layer, the patterning fluid including a latent binder.
