Abstract
An example of a kit for three-dimensional (3D) printing includes an ultraviolet (UV) light fusing agent. The ultraviolet (UV) light fusing agent includes an aqueous vehicle and a B vitamin or a B vitamin derivative present in an amount that dissolves in the aqueous vehicle. The aqueous vehicle includes a co-solvent, a surfactant, and water. The B vitamin or the B vitamin derivative has absorption at wavelengths ranging from about 340 nm to about 415 nm.
Claims12
A kit for three-dimensional (3D) printing, the kit comprising:
- an ultraviolet (UV) light fusing agent including:
- an aqueous solution vehicle including a co-solvent, a surfactant, water, and a B vitamin or a B vitamin derivative, the B vitamin or the B vitamin derivative having absorption at wavelengths ranging from about 340 nm to about 415 nm,
- wherein the B vitamin or B vitamin derivative is selected from the group consisting of folic acid, cyanocobalamin, pantothenic acid, biotin, pyridoxine, and combinations thereof.
A method for three-dimensional (3D) printing, the method comprising:
- applying a polymeric build material composition to form a build material layer;
- based on a 3D object model, selectively applying an ultraviolet (UV) light fusing agent on at least a portion of the build material layer, the UV light fusing agent including:
- an aqueous solution of a co-solvent, a surfactant, and water, and
- a B vitamin or the B vitamin derivative, the B vitamin or the B vitamin derivative having absorption at wavelengths ranging from about 340 nm to about 415 nm,
- wherein the B vitamin or B vitamin derivative is selected from the group consisting of folic acid, cyanocobalamin, pantothenic acid, biotin, pyridoxine, and combinations thereof;
- and
- exposing the build material layer to UV radiation to coalesce the at least the portion to form a layer of a 3D object.
