Abstract: Example post-print processing of three dimensional (3D) printed objects are disclosed. An example system includes an energy source to apply energy to a selected portion of an outer surface of a 3D printed object. The energy provided by the energy source is to cause a polymer of the selected portion to melt and reflow. The selected portion and a non-selected portion of the outer surface to form a pattern on the outer surface of the 3D printed object. A controller to direct the energy of the energy source to the selected portion of the outer surface.
