Additive manufacturing process using fusing and non-fusing printing fluids

A method, comprising:

• generating, by a processing system of an additive manufacturing system, a model for fabricating a plurality of objects, wherein the model includes a first region defining each one of the plurality of objects and a second region defining a sacrificial artifact that forms a boundary with un-fused powder around each one of the plurality of objects formed with fused powder;
• and
• controlling, by the processing system, the print engine to fabricate the sacrificial artifact simultaneously with fabricating the plurality of objects, wherein at least one of the plurality of objects is printed using a first colored fusing printing fluid, a second colored fusing printing fluid, a first colored non-fusing printing fluid, and a second colored non-fusing printing fluid, wherein the first colored fusing printing fluid and the first colored non-fusing printing fluid have a same color and the second colored fusing printing fluid and the second colored non-fusing printing fluid have a same color, wherein the first colored fusing printing fluid and the first colored non-fusing printing fluid are a different color from the second colored fusing printing fluid and the second colored non-fusing printing fluid, wherein the first colored fusing printing fluid is used on a first portion of an object of the plurality of objects and the first colored non-fusing printing fluid is used adjacent to the first colored fusing printing fluid, and wherein a second colored fusing printing fluid is used on a second portion of the object and the second colored non-fusing printing fluid is used adjacent to the second colored fusing printing fluid to hide a number of the plurality of objects that are printed as well as a geometry of each one of the plurality of objects, wherein the second region formed around the boundary of each one of the plurality of objects comprises:
• a buffer portion that directly physically contacts the first region and is fabricated using the non-fusing printing fluid;
• and
• an additional portion that directly physically contacts the buffer portion without directly physically contacting the first region, where the additional portion is fabricated using the fusing printing fluid.
