Abstract
A three-dimensional (3D) object printer includes a surface treatment system configured to treat layers of an object being formed by the printer with a moving ultraviolet (UV) laser. The movement of the laser is controlled with a scanning mirror system and the spot size of the laser is reduced with a focus lens having a numerical aperture in a range of about 0.5 to about 1.0.
