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 firstsurface 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 areaof the article and are configured such that the article has a gas permeability between about 10 barrers and about 2000 barrers.

Description

[0001] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Application Serial No. 62 / 139,238, filed March 27, 2015, which application is based upon and is hereby incorporated by reference in its entirety. Background technique [0002] Generally, polymeric materials have poor transmittance for light having wavelengths in the ultraviolet spectral region. In addition to this, polymeric materials typically have lower stiffness values ​​than other light-transmitting materials. Furthermore, processing polymeric materials to render them permeable to certain gases can negatively impact the transmittance and stiffness properties of the polymeric materials. Accordingly, it would be desirable to create articles that are simultaneously rigid and transparent to UV light, but also breathable. Contents of the invention [0003] According to one embodiment, a gas permeable glazing suitable for liquid interface additive manufacturing comprises a light transmissive glaz...
