Abstract
In an example, a three-dimensional (3D) printed part comprises a plurality of fused build material layers including exterior layers and interior layers. At least some of the interior layers include a composite portion having a miscible solid physically bonded to an amide functionality or an amine functionality of the build material. The miscible solid is a solid at a room temperature ranging from about 18° C. to about 25° C.
Claims15
A three-dimensional (3D) printed part, comprising:
- a plurality of fused build material layers including exterior layers and interior layers, at least some of the interior layers including a composite portion having a miscible solid physically bonded to an amide functionality or an amine functionality of the build material, the miscible solid being a solid at a room temperature ranging from about 18° C. to about 25° C.
A three-dimensional (3D) printing method, comprising:
- applying a build material containing an amide functionality or an amine functionality;
- patterning at least a portion of the build material by:
- selectively applying a fusing agent on the portion of the build material;
- and
- selectively jetting a ductility tailoring agent on at least a region of the portion, the ductility tailoring agent including a water-based solvent system and a miscible solid that is at least partially soluble in the water-based solvent system and that is compatible with the amide functionality or the amine functionality of the build material;
- and
- exposing the build material, including the patterned portion, to radiation, thereby fusing the patterned portion to form a layer;
- wherein the miscible solid forms a composite portion in the layer.
A three-dimensional (3D) printing system, comprising:
- a supply of a build material containing an amide functionality or an amine functionality;
- a build material distributor;
- a supply of a fusing agent;
- a first inkjet applicator for selectively dispensing the fusing agent;
- a supply of an inkjettable ductility tailoring agent, the inkjettable ductility tailoring agent including a water-based solvent system and a miscible solid that is at least partially soluble in the water-based solvent system and that is compatible with the amide functionality or the amine functionality of the build material;
- a second inkjet applicator for selectively dispensing the inkjettable ductility tailoring agent;
- a controller;
- and
- a non-transitory computer readable medium having stored thereon computer executable instructions to cause the controller to:
- utilize the build material distributor to dispense the build material;
- and
- utilize the first inkjet applicator and the second inkjet applicator to respectively and selectively dispense the fusing agent and the inkjettable ductility tailoring agent to pattern layers of the build material during a three-dimensional printing process.
