Abstract
A particulate build material for three-dimensional printing can include from about 80 wt % to about 99.5 wt % of a polyamide particles, and from about 0.5 w % to about 7.5 wt % of thermally conductive particles including cubic lattice structured particles of carbon, cubic lattice structured particles of boron and nitrogen, or a combination thereof.
Claims15
A particulate build material for three-dimensional printing, comprising:
- from about 80 wt % to about 99.5 wt % of a polyamide particles;
- and
- from about 0.5 w % to about 7.5 wt % of thermally conductive particles including cubic lattice structured particles of carbon, cubic lattice structured particles of boron and nitrogen, or a combination thereof.
A three-dimensional printing system, comprising:
- a particulate build material including from about 80 wt % to about 99.5 wt % of a polyamide particles and from about 0.5 w % to about 7.5 wt % of thermally conductive particles including cubic lattice structured particles of carbon, cubic lattice structured particles of boron and nitrogen, or a combination thereof;
- and
- a fusing agent to selectively apply to the particulate build material, wherein the fusing agent comprises water and a radiation absorber to absorb radiation energy and convert the radiation energy to heat.
A method of printing a three-dimensional object comprising:
- iteratively applying individual layers of a particulate build material to a powder bed, wherein the particulate build material comprises from about 80 wt % to about 99.5 wt % of a polyamide particles and from about 0.5 w % to about 7.5 wt % of thermally conductive particles including cubic lattice structured particles of carbon, cubic lattice structured particles of boron and nitrogen, or a combination thereof;
- based on a three-dimensional object model, selectively applying a fusing agent onto the individual layers of particulate build material, wherein the fusing agent comprises water and a radiation absorber, wherein the radiation absorber absorbs radiation energy and converts the radiation energy to heat;
- and
- exposing the powder bed to radiation energy to selectively fuse the polyamide particles in contact with the radiation absorber at individual layers to iteratively form the three-dimensional object with the thermally conductive particles dispersed therein.
