APPARATUS AND METHOD FOR FORMING THREE-DIMENSIONAL OBJECTS USING LINEAR SOLIDIFICATION

摘要

An apparatus and method for making a three-dimensional object from a solidifiable material using a linear solidification device is shown and described. In certain examples, the linear solidification device includes a laser diode that projects light onto a scanning device, such as a rotating polygonal mirror or a laser scanning micromirror, which then deflects the light onto a photohardenable resin. As a result, the linear solidification device scans a line of solidification energy in a direction that is substantially orthogonal to the direction of travel of the laser diode. In other examples, the linear solidification device is a laser device array or light emitting diode array that extends in a direction substantially orthogonal to the direction of travel of the array.

1. A method of making a three-dimensional object from a solidifiable material, comprising:
moving a source of solidification energy in a first direction; progressively exposing portions of the solidifiable material to solidification energy in a second direction along an exposed surface of the solidifiable material as the source of solidification energy moves in the first direction.
