Abstract
An example of a multi-fluid kit for three-dimensional (3D) printing includes a fusing agent and a surface treating agent. The fusing agent includes an electromagnetic radiation absorber and a first aqueous vehicle. The surface treating agent includes a second aqueous vehicle, a surfactant, and benzyl alcohol dissolved in the second aqueous vehicle.
Claims15
A multi-fluid kit for three-dimensional (3D) printing, comprising:
- a fusing agent including:
- an electromagnetic radiation absorber;
- and
- a first aqueous vehicle;
- and
- a surface treating agent including:
- a second aqueous vehicle;
- a surfactant;
- and
- benzyl alcohol dissolved in the second aqueous vehicle.
7 more elements
A method for three-dimensional (3D) printing, comprising:
- applying a polyamide build material composition to form a build material layer;
- based on a 3D object model, selectively applying a fusing agent on at least a portion of the build material layer, thereby forming a patterned portion;
- based on the 3D object model, selectively applying a surface treating agent onto at least a portion of the patterned portion, the surface treating agent including:
- an aqueous vehicle;
- a surfactant;
- and
- benzyl alcohol dissolved in the aqueous vehicle;
- and
- exposing the build material layer to electromagnetic radiation to selectively coalesce the patterned portion and form a 3D object layer.
