3D laser perforation thermal sagging process

Abstract

In some embodiments, a method of forming a glass article comprises perforating a glass substrate along a contour with a laser forming a plurality of perforations, such that the contour separates a first portion of the glass substrate from a second portion of the glass substrate; after perforating, thermal forming the glass substrate into a non-planar shape with a mold, and separating the first portion of the glass substrate from the second portion of the glass substrate.
