Abstract
According to examples described herein, methods, compositions, and agents comprising an antistatic agent are described. According to one example, a fusing agent composition for three-dimensional printing can comprise: at least one antistatic agent in an amount of from about 0.01 wt % to about 20 wt % based on a total weight of the fusing agent composition, at least one near infrared absorbing compound, at least one surfactant, at least one organic solvent, and water.
Claims15
A fusing agent composition for three-dimensional printing comprising:
- at least one antistatic agent in an amount of from about 0.01 wt % to about 20 wt % based on a total weight of the fusing agent composition,
- at least one near infrared absorbing compound,
- at least one surfactant,
- at least one organic solvent, and
- water.
A liquid functional agent composition for three-dimensional printing comprising:
- (A) a first fusing agent comprising:
- at least one first antistatic agent,
- at least one first near infrared absorbing compound,
- at least one surfactant,
- at least one organic solvent, and
- water;
- (B) a second fusing agent comprising at least one second near infrared absorbing compound;
- (C) a first detailing agent;
- and
- (D) a second detailing agent free of any near infrared absorbing compound.
A method of applying a liquid functional agent in three-dimensional printing comprising:
- (A) (i) depositing a layer of build material, (ii) selectively applying a first fusing agent on the build material, and (iii) repeating (i) and (ii) at least once to form a core of a three-dimensional part;
- wherein the first fusing agent comprises:
- at least one first antistatic agent,
- at least one first near infrared absorbing compound,
- at least one surfactant,
- at least one organic solvent, and
- water;
- (B) applying a second fusing agent and a first detailing agent on the core of the three-dimensional part to form an inner shell at least partially enclosing the core, wherein the first detailing agent comprises at least one second antistatic agent;
- and
- (C) applying a second detailing agent on the inner shell, wherein the second detailing agent is free of any near infrared absorbing compound.
