摘要： 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.

摘要： A method of three-dimensional printing comprises heating a first portion of a build surface on a platform by impinging a laser beam on the build surface so as to provide a preheated drop contact point having a first deposition temperature. A first drop of a liquid print material is ejected from a printhead of a 3D printer so as to deposit the first drop on the preheated drop contact point at the first deposition temperature.
