摘要： In an example, a virtual build volume comprising a representation of at least a part of an object to be generated in additive manufacturing is segmented into a plurality of nested segments comprising a core segment, an inner peripheral segment and an outer peripheral segment. Additive manufacturing control instructions may be generated for the nested segments. The control instructions for the core segment may provide a first region of the object corresponding to the core segment and having a first color. The control instructions for the outer peripheral segment may provide a second color for a second region of the object corresponding to the outer peripheral segment. The control instructions for the inner peripheral segment may provide a third color for a third region of the object corresponding to the inner peripheral segment, wherein a color of the third region is determined so as to at least partially visually mask the first region.

摘要： An example inkjet primer fluid includes an alkoxysilane, a surfactant, a co-solvent, and a balance of water; and is at least substantially colorless. In an example method, a primer fluid, including an alkoxysilane, a surfactant, a co-solvent, and a balance of water, is thermal inkjet printed from a thermal inkjet printhead to form a silicon dioxide film on a resistor. Then, a jettable composition, including suspended nanoparticles, is thermal inkjet printed from the thermal inkjet printhead. In another example method, suspended nanoparticles, an alkoxysilane, and a growth mediator are combined to form a mixture. The mixture is heated to a temperature ranging from about 60° C. to about 80° C. and stirred for about 12 hours to about 36 hours to form silicon dioxide coated, suspended nanoparticles. Then, a surfactant, a zwitterionic stabilizer, a co-solvent, and a balance of water are added to the mixture to form a stabilized, jettable composition.

摘要： 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.

摘要： Disclosed herein is a three-dimensional printing method comprising: applying a build material; applying on, at least, a portion of the build material, a low tint fusing agent composition comprising metal oxide nanoparticles dispersed in a liquid vehicle; and exposing the build material to radiations to fuse the portion of the build material in contact with the low tint fusing agent composition in order to form a layer of a 3D object. Also disclosed herein is an article obtained according to the three-dimensional printing method described herein. Such articles comprises a core substrate made of a polymeric build material that has been fused with a core fusing agent composition; a first layer, applied on the surface of the core substrate, comprising a polymeric build material fused with a low tint fusing agent composition including metal oxide nanoparticles dispersed in a liquid vehicle; and a second layer, applied over the surface of the first layer, comprising a polymeric build material fused with a colored ink composition and a core fusing agent or with a low tint fusing agent composition colored ink composition.
