METHOD AND APPARATUS USING LIGHT ENGINES FOR PHOTO-CURING OF LIQUID POLYMERS TO FORM THREE-DIMENSIONAL OBJECTS
Three-dimensional objects are formed by photo-curing a liquid polymer by exposure to a radiation, which radiation (e.g., at 410 nm) is provided by a collimated light source composed of an array of light emitting diode (LED) sources, an array of baffles, and an array of lenses. The baffles limit beam...

Summary: | Three-dimensional objects are formed by photo-curing a liquid polymer by exposure to a radiation, which radiation (e.g., at 410 nm) is provided by a collimated light source composed of an array of light emitting diode (LED) sources, an array of baffles, and an array of lenses. The baffles limit beam widths of each individual LED source in the array of LED, and the array of lenses is located one focal length from said array of LED sources. |
