Abstract
A fusing agent for three-dimensional printing can include from about 5 wt % to about 40 wt % water; from about 4 wt % to about 60 wt % C7 to C12 aliphatic ester cosolvent; and from about 0.5 wt % to about 10 wt % solubilized avobenzone.
Claims15
A fusing agent for three-dimensional printing, comprising:
- from about 5 wt % to about 40 wt % water;
- from about 4 wt % to about 60 wt % C7 to C12 aliphatic ester cosolvent;
- and
- from about 0.5 wt % to about 10 wt % solubilized avobenzone.

A method of making a fusing agent for three-dimensional printing, comprising:
- dissolving avobenzone in C7 to C12 aliphatic ester cosolvent at a weight ratio of about 1:8 to about 1:20 to form an avobenzone organic solution;
- and
- admixing additional organic cosolvent and water with the avobenzone organic solution to form a fusing agent, wherein the fusing agent includes from about 0.5 wt % to about 10 wt % of solubilized avobenzone.
A method of three-dimensional printing, comprising:
- iteratively applying individual build material layers of a polymer build material including from about 80 wt % to 100 wt % polymeric particles;
- based on a three-dimensional object model, iteratively and selectively dispensing a fusing agent onto the individual build material layers, wherein the fusing agent includes from about 0.5 wt % to about 10 wt % solubilized avobenzone;
- and
- iteratively exposing the powder bed to ultraviolet light energy for a time duration of about 0.1 second to about 10 seconds to selectively fuse the polymeric particles in contact with the solubilized avobenzone at the individual build material layers resulting in a fused three-dimensional object.
