Abstract: A method for printing a three-dimensional object in a volume of a photopolymerizable liquid by photopolymerization, the method comprising: (a) providing a digital representation of a three-dimensional object that has been sliced into a plurality of sequential two-dimensional image slices along the z-direction; (b) processing each of the two-dimensional slices of the three-dimensional object into a sequence of subsampled images, each subsampled image comprising an arrangement of pixels wherein each pixel has defined x and y dimensions; (c) sequentially exposing each of the sequence of subsampled images of a slice at a selected location along the z-direction in the volume using excitation light until the volume at the selected location along the z-direction has been exposed to all of the subsampled images of the slice, and (d) sequentially repeating step (c) for a previously unexposed sequential slice of the three-dimensional object, each at different selected location along the z-direction, until the three-dim

Abstract: The present invention relates to methods and systems for volumetric printing a three-dimensional object. The methods and systems include achieving polymerization in a photopolymerizable liquid at the intersection of a first optical projection of excitation light and second optical projection of excitation light comprising a sheet of excitation light.

Abstract: A light mixing chamber of a backlight includes a housing having a channel and a chamber exposed to the channel, an LED positioned within the chamber, and a capillary containing quantum dots positioned in the channel. A light guide plate is positioned adjacent the housing and adjacent the capillary. Relative dimensions of the elements of the light mixing chamber, as well as features added to the elements of the light mixing chamber, can be varied to balance efficiency and uniformity of light generated in the backlight.
