Abstract
In an example of a method for reducing oxidation of a build material during three-dimensional printing, a portion of a layer of a polymeric build material is patterned by selectively applying a fusing agent on the portion. A detailing agent selectively applied on a non-patterned portion of the layer. The detailing agent includes a stabilizer to reduce oxidation of the polymeric build material. The layer is exposed to electromagnetic radiation to fuse the portion to form a 3D object layer. The stabilizer at least minimizes discoloration of the non-patterned portion.
