Abstract
A detailing agent for three-dimensional (3D) printing includes a colorant present in an amount ranging from about 1.00 wt % to about 3.00 wt % based on a total weight of the detailing agent. The colorant is a dye having substantially no absorbance in a range of 650 nm to 2500 nm. The detailing agent also includes a co-solvent, a surfactant, and a balance of water.
Claims15
A detailing agent for three-dimensional (3D) printing, comprising:
- a colorant present in an amount ranging from about 1.00 wt % to about 3.00 wt % based on a total weight of the detailing agent, wherein the colorant is a dye having substantially no absorbance in a range of 650 nm to 2500 nm;
- a co-solvent;
- a surfactant;
- and
- a balance of water.
2 more elements
A three-dimensional (3D) printing method, comprising:
- applying a build material;
- heating the build material to a temperature ranging from about 50° C. to about 400° C.;
- selectively applying a fusing agent on a portion of the build material;
- selectively applying a detailing agent on an other portion of the build material outside an edge boundary of the portion of the build material, the detailing agent penetrating the other portion of the build material and dying an area of the portion of the build material adjacent to the edge boundary, the detailing agent including:
- a colorant present in an amount ranging from about 1.00 wt % to about 3.00 wt % based on a total weight of the detailing agent, wherein the colorant is a dye having substantially no absorbance in a range of 650 nm to 2500 nm;
- a co-solvent;
- a surfactant;
- and
- a balance of water;
- and
- exposing the build material to radiation, whereby the fusing agent at least partially fuses the portion of the build material in contact with the fusing agent, and the detailing agent prevents fusing of the other portion of the build material in contact with the detailing agent.
