Abstract
A gas permeable glass window, suitable for use with liquid interface additive manufacturing, has an optically transparent glass article greater than about 0.5 millimeters in thickness defining a first surface and a second surface. A plurality of gas channels are disposed through the article from the first surface to the second surface. The gas channels occupy less than about 1.0% of a surface area of the article and are configured such that the article has a gas permeability between about 10 barrers and about 2000 barrers.
