Abstract
A shear thinning build material slurry includes metallic or ceramic particles having a particle size up to about 20 ?m; 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.
Claims19
A shear thinning build material slurry, comprising:
- metallic build material particles selected from the group consisting of steel particles, stainless steel particles, bronze particles, titanium particles and alloys thereof, nickel particles, cobalt particles, iron particles and alloys thereof, gold particles and alloys thereof, silver particles and alloys thereof, platinum particles and alloys thereof, and copper particles and alloys thereof, wherein the build material particles have a particle size ranging from about 5 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, the hydrocolloid having a molecular weight ranging from about 0.5×106 g/mol to about 50×106 g/mol and is selected from the group consisting of xanthan gum, scleroglucan, diutan gum, rhamsan gum, guar gum, locust bean gum, tara gum, cassia gum, gum tragacanth, welan gum, carrageenan, flaxseed gum, tamarind gum, konjac maanan, agarose, gellan gum, and combinations thereof;
- and
- water,
- wherein the build material slurry is a ready-to-use three-dimensional (3D) printing build material.
