3-D printing method

A three-dimensional printing method is disclosed herein， the method comprising: applying a building material; Applying a light-colored fusing agent comprising metal oxide nanoparticles dispersed in a liquid carrier over at least a portion of the building material; And exposing the building material to radiation to fuse a portion of the building material in contact with the tinted fusing agent composition to form a layer of the 3D object. Articles obtained according to the three-dimensional printing method described herein are also disclosed herein. Such articles include a core substrate made of a polymeric building material fused with a core fusing agent composition; A first layer comprising a polymer building material applied to the surface of the core substrate and fused with a tinted fusing agent composition comprising metal oxide nanoparticles dispersed in a liquid carrier; And a second layer applied on the surface of the first layer and comprising a polymeric building material fused with the colored ink composition and the core fusing agent or the tinted fusing agent composition colored ink composition. 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.
