Abstract
In example implementations, a three-dimensional printing kit for printing a colorless three-dimensional object in a three-dimensional printing system is provided. The three-dimensional printing kit includes a build material and an ultraviolet (UV) fusing agent. The UV fusing agent includes water, a UV light absorber, about 10-50 weight percent (wt %) of a first solvent to provide a polymer plasticizer, and about 30-50 wt % a second solvent that is water miscible and dissolves the UV light absorber.
Claims15
A three-dimensional printing kit, comprising:
- a build material;
- and
- an ultraviolet (UV) fusing agent, comprising:
- water;
- a UV light absorber that is a substituted cresol;
- 10-50 weight percent (wt %) of a first solvent that is a plasticizing solvent;
- and
- 30-50 wt % of a second solvent that is water miscible and dissolves the UV light absorber.
A three-dimensional printing system, comprising:
- a powder bed comprising a layer of build material;
- a fusing agent applicator fluidly coupled to a supply of an ultraviolet (UV) fusing agent, wherein the fusing agent applicator is to iteratively apply the UV fusing agent to the layer of build material, wherein the UV fusing agent comprises water, a UV light absorber that is a substituted cresol, 10-50 weight percent (wt %) of a first solvent that is a plasticizing solvent, and 30-50 wt % of a second solvent that is water miscible and dissolves the UV light absorber;
- and
- a fusing lamp positioned to emit UV light to heat a portion of the powder bed that received the UV fusing agent to a fusing temperature.
A method of printing a colorless three-dimensional object, the method comprising:
- selectively applying an ultraviolet (UV) fusing agent onto a build material, wherein the UV fusing agent comprises water, a UV light absorber that is a substituted cresol, 10-50 weight percent (wt %) of a first solvent that is a plasticizing solvent, and 30-50 wt % of a second solvent that is water miscible and dissolves the UV light absorber;
- and
- heating the build material and the UV fusing agent that is selectively applied with a UV light to fuse a layer of the colorless three-dimensional object.
