Abstract
The present disclosure relates a method of 3-dimensional printing a printed part. The method comprises printing an inkjet dopant composition at selected locations on a layer of build material comprising polymer particles. The inkjet dopant composition comprises a dopant dispersed or dissolved in a liquid carrier. Polymer particles at selected areas of the layer of build material are then fused to form a fused polymer layer comprising the dopant. The selected areas of the layer of build material include areas of the layer of build material that have not been printed with the inkjet dopant composition.
Claims16
A 3-dimensional printing material set, comprising:
- a particulate build material comprising thermoplastic polymer particles;
- an inkjet dopant composition consisting of:
- a liquid carrier consisting of:
- from about 73 wt % to about 76 wt % of water;
- a co-solvent;
- and
- optionally a surfactant;
- and
- a dopant dispersed or dissolved in the liquid carrier, wherein the dopant is present in an amount ranging from about 0.1 wt % to about 5 wt % and consists of particles that are selected from at least one of photoluminescent particles, dielectric particles, magnetic particles, ceramic particles, semi-conductor particles, electrically-conducting particles, and polymer nanoparticles;
- and
- an inkjet fusing composition consisting of a liquid vehicle water and a fusing agent capable of absorbing electromagnetic radiation to produce heat, wherein;
- the fusing agent is selected from the group consisting of carbon black, near-infrared absorbing pigments, tungsten bronzes, molybdenum bronzes, metal nanoparticles, and combinations thereof;
- and
- the liquid vehicle consists of water.
