Abstract
A three-dimensional printing kit can include a build material with from about 80 wt % to 100 wt % polymeric particles having a D50 particle size from about 10 μm to about 150 μm, and a fusing agent including from about 0.5 wt % to about 20 wt % avobenzone particles dispersed in an aqueous liquid vehicle based on a total weight of the fusing agent.
Claims13
A three-dimensional printing kit, comprising:
- a build material including from about 80 wt % to 100 wt % of polymeric particles having a D50 particle size ranging from about 10 μm to about 150 μm;
- and
- a fusing agent including from about 0.5 wt % to about 20 wt % of avobenzone particles dispersed in an aqueous liquid vehicle based on a total weight of the fusing agent.
A method for three-dimensional printing, the method comprising:
- iteratively applying individual build material layers of a polymer build material including from about 80 wt % to 100 wt % of polymeric particles having a D50 particle size of from about 10 μm to about 150 μm to a powder bed;
- 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 20 wt % of avobenzone particles dispersed in an aqueous liquid vehicle based on a total weight of the fusing agent;
- and
- iteratively exposing the powder bed to light energy having a peak wavelength of from about 350 nm to about 415 nm for a time duration of from about 0.1 second to about 10 seconds to selectively fuse the polymeric particles in contact with the avobenzone particles at the individual build material layers resulting in a fused three-dimensional object.
