Abstract

A method includes ejecting a plurality of drops of a build material from a nozzle of a 3D printer. The build material cools and solidifies after being ejected to form a 3D object. The method also includes controlling an oxidation of the drops, the 3D object or both to create different oxidation levels in first and second portions of the 3D object.
