Abstract: Disclosed herein are kits, methods, systems, and compositions for threedimensional printing. In an example, disclosed herein is a multi-fluid kit for threedimensional printing comprising: a marking agent comprising a marking component which is a fluorescent color agent that is activated by ultraviolet radiation to emit light in the visible range of from about 400 nm to about 780 nm; a first fusing agent; a second fusing agent different from the first fusing agent; and a detailing agent.

Abstract: In one example a system is for post-processing a three-dimensional (3D) object generated in an additive manufacturing process in which an identifiable agent is applied to a portion of a build material to form a portion of the 3D object. The system comprises an identification unit and a sensor. The identification unit is to cause the identifiable agent to become distinguishable to thereby cause the portion of the 3D object, corresponding to the portion of build material to which the identifiable agent was applied, to be distinguishable from any build material remnant disposed on the 3D object and to which no identifiable agent was applied. The sensor is to distinguish the build material remnant from the portion of the 3D object.

Abstract: The present disclosure relates to light guide plates and methods for three-dimensional printing of light guide plates. In some examples, the method for 3D printing a light guide plate comprises: forming a plate body by depositing a layer of transparent build material on a build platform; based on a 3D object model of the plate body, inkjet printing fusing agent onto at least a portion of the layer of the transparent build material; and irradiating the fusing agent to heat the transparent build material and at least partially bind the portion of the transparent build material. In some examples, light scattering features are formed on the plate body by depositing a layer of transparent build material on the plate body; based on a 3D object model of light scattering features, inkjet printing fusing agent and scattering particles onto selected portions of the layer of transparent build material; and irradiating the fusing agent to heat the transparent build material and at least partially bind the portion of the transparent build material.
