Abstract: A metallic build material granule includes a plurality of primary metal particles and a temporary binder agglomerating the plurality of primary metal particles together. The primary metal particles have a primary metal particle size ranging from about the 1 μm to about 20 μm. The primary metal particles are non-shape memory metal particles, and the metallic build material granule excludes shape memory metal particles.

Abstract: In an example of a method for three-dimensional (3D) printing, a polymeric or polymeric composite build material is applied. A dielectric agent is selectively applied on at least a portion of the polymeric or polymeric composite build material. The dielectric agent includes a dielectric material having an effective relative permittivity (εr) value ranging from 1.1 to about 10,000. A fusing agent is selectively applied on the at least the portion of the polymeric or polymeric composite build material, and the polymeric or polymeric composite build material is exposed to radiation to fuse the at least the portion of the polymeric or polymeric composite build material to form a region of a layer of a 3D part. The region exhibits a dielectric property, a piezoelectric property, or a combination thereof.

Abstract: The present disclosure is drawn to 3-dimensional printed parts that can include a conductive composite portion and an insulating portion. The conductive composite portion can include a matrix of fused thermoplastic polymer particles interlocked with a matrix of sintered elemental transition metal particles. The insulating portion can include a matrix of fused thermoplastic polymer particles that are continuous with the matrix of fused thermoplastic polymer particles in the conductive composite portion. The insulating portion can be substantially free of sintered elemental transition metal particles and can include transition metal oxide bronze particles.
