Material sets
The present disclosure is drawn to material sets and 3-dimensional printing systems that include a fusing agent. One example of a material set can include a fusing agent and a detailing agent. The fusing agent can include water, a carbon black pigment, and a water-soluble co-solvent in an amount from 20 wt % to 60 wt %. The detailing agent can include water and a black dye. In another example, a material set can include a fusing agent and a thermoplastic polymer powder.
1. A material set, comprising:
a detailing agent, comprising:
water,
a black dye,
a cyan dye, and
a water-soluble co-solvent consisting of triethylene glycol and 2-pyrrolidone, present in the detailing agent at an amount from 10 wt % to 20 wt %; and
a fusing agent, comprising:
water, and
a carbon black pigment.
2. The material set of claim 1 , wherein a weight ratio of the black dye to the cyan dye is from 3:1 to 10:1.
3. The material set of claim 1 , wherein the black dye is present in an amount from 1 wt % to 4 wt % with respect to the total weight of the detailing agent.
4. The material set of claim 1 , wherein the detailing agent includes the water in an amount from 70 wt % to 90 wt %.
5. The material set of claim 1 , wherein the triethylene glycol is present in an amount from 5 wt % to 15 wt % with respect to the total weight of the detailing agent, and wherein the 2-pyrrolidone is present in an amount from 2 wt % to 5 wt % with respect to the total weight of the detailing agent.
6. The material set of claim 1 , wherein the fusing agent further comprises a water-soluble co-solvent consisting of triethylene glycol and 2-pyrrolidone, and wherein the triethylene glycol in the fusing agent is present in an amount ranging from 5 wt % to 20 wt % with respect to the total weight of the fusing agent, and the 2-pyrrolidone in the fusing agent is present in an amount ranging from 10 wt % to 40 wt % with respect to the total weight of the fusing agent.
7. The material set of claim 6 , wherein a ratio of 2-pyrrolidone to triethylene glycol in the detailing agent is less than 1:1; and wherein a ratio of 2-pyrrolidone to triethylene glycol in the fusing agent is greater than 1:1.
8. The material set of claim 1 , wherein a ratio of 2-pyrrolidone to triethylene glycol in the detailing agent ranges from 0.33:1 to 0.4:1.
9. A material set, comprising:
a detailing agent, comprising:
water,
a black dye,
a cyan dye, and
a water-soluble co-solvent consisting of triethylene glycol and 2-pyrrolidone, present in the detailing agent at an amount from 10 wt % to 20 wt %;
a fusing agent, comprising:
water, and
a carbon black pigment; and
a thermoplastic polymer powder.
10. The material set of claim 9 , wherein the thermoplastic polymer powder has an average particle size from 10 microns to 200 microns.
11. The material set of claim 9 , wherein the thermoplastic polymer powder comprises polyamide-6 powder, polyamide-9 powder, polyimide-11 powder, polyamide-12 powder, polyamide-66 powder, polyamide-612 powder, polyethylene powder, thermoplastic polyurethane powder, polypropylene powder, polyester powder, polycarbonate powder, polyether ketone powder, polyacrylate powder, polystyrene powder, or a combination thereof.
12. The material set of claim 9 , wherein a weight ratio of the black dye to the cyan dye is from 3:1 to 10:1.
13. The material set of claim 9 , wherein the black dye is present in an amount from 1 wt % to 4 wt % with respect to the total weight of the detailing agent.
