Abstract
A three-dimensional printing kit can include a polymeric build material and a fusing agent. The polymeric build material can include polymer particles having a D50 particle size from about 2 μm to about 150 μm. The fusing agent can include an aqueous liquid vehicle including water and an organic co-solvent, a radiation absorber to generate heat from absorbed electromagnetic radiation, and from about 2 wt % to about 15 wt % of a carbamide-containing compound.
Claims19
A three-dimensional printing kit, comprising:
- a polymeric build material including polymer particles having a D50 particle size of from about 2 μm to about 150 μm;
- and
- a fusing agent comprising:
- an aqueous liquid vehicle including water and an organic co-solvent;
- a radiation absorber to generate heat from absorbed electromagnetic radiation;
- and
- a carbamide-containing compound present in an amount from about 2 wt % to about 15 wt %, based on a total weight of the fusing agent.
A method of printing three-dimensional object, the method comprising:
- iteratively applying individual polymeric build material layers including polymer particles having a D50 particle size of from about 2 μm to about 150 μm;
- based on a three-dimensional object model, iteratively and selectively dispensing a fusing agent onto the individual build material layers, wherein the fusing agent comprises:
- an aqueous liquid vehicle including water and an organic co-solvent;
- a radiation absorber to generate heat from absorbed electromagnetic radiation;
- and
- a carbamide-containing compound present in an amount from about 2 wt % to about 15 wt %, based on a total weight of the fusing agent;
- and
- iteratively exposing the individual polymeric build material layers with the fusing agent dispensed thereon to the electromagnetic radiation to selectively fuse the polymer particles of the polymeric build material in contact with the radiation absorber and to form a fused three-dimensional object.
A three-dimensional printing system, comprising:
- a polymeric build material including polymer particles having a D50 particle size of from about 2 μm to about 150 μm;
- and
- a fluid applicator fluidly coupled or coupleable to a fusing agent, wherein the fluid applicator is directable to iteratively apply the fusing agent to layers of the polymeric build material, the fusing agent comprising:
- an aqueous liquid vehicle including water and an organic co-solvent;
- a radiation absorber to generate heat from absorbed electromagnetic radiation;
- and
- a carbamide-containing compound present in an amount from about 2 wt % to about 15 wt %, based on a total weight of the fusing agent.
