Abstract
Three-dimensional printing kits can include a powder bed material and a fusing agent to selectively apply to the powder bed material. The powder bed material can include polymer build particles and cellulose particles. The cellulose particles can be chemically and thermally stable at a melting point temperature of the polymer build particles. The fusing agent can include water and a radiation absorber to absorb radiation energy and convert the radiation energy to heat.
Claims21
A particulate build material for three-dimensional printing, the particulate build material comprising:
- polyamide particles;
- and
- thermally conductive particles dry blended with the polyamide particles, the thermally conductive particles having a cubic lattice structure.
-12. (canceled)
A method of printing a three-dimensional object, the method comprising:
- iteratively applying individual layers of a particulate build material to a powder bed, wherein the particulate build material comprises polyamide particles and thermally conductive particles having a cubic lattice structure;
- based on a three-dimensional object model, selectively applying a fusing agent onto the individual layers of the particulate build material, wherein the fusing agent comprises water and a radiation absorber;
- and
- exposing the powder bed to radiation energy to selectively fuse the polyamide particles in contact with the radiation absorber to form the three-dimensional object with the thermally conductive particles dispersed therein.
