Abstract:
1. An apparatus for making a three-dimensional object from a photohardenable resin comprising: a source of the photohardenable resin; a linear solification device including a selectively activatable and deactivatable ultraviolet laser diode and a rotating polygonal mirror, wherein the linear solification device moveable in a first direction, ultraviolet laser diode selectively projects solidification energy in a second direction as it moves in the first direction, the rotating polygonal mirror is rotatable in a rotation plane that is substantially perpendicular to the first direction, the rotating polygonal mirror is in optical communication with the ultraviolet laser diode, and when the ultraviot laser diode projects solidification energy in the second direction, the rotating polygonal mirror deflects the solidification energy toward the photohardenable resin, and the deflected solidification energy solidifies the photohardenable resin.
