Abstract:
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.
