According to examples described herein, methods, compositions, and parts comprising an antistatic agent are described. According to one example, a method of three-dimensional printing can comprise: (i) a layer of build material being deposited; (ii) a first fusing agent being selectively applied on the build material, wherein the first fusing agent can comprise at least one first antistatic agent; and (iii) repetition of (i) and (ii) at least once to form a core of a three-dimensional part.
