Abstract
The present disclosure describes methods of attaching surfaces together. In one aspect, a method includes depositing a first adhesive onto a first surface of a first item, the first adhesive forming a pattern that at least partially surrounds a region of the first surface where there is no first adhesive. A second adhesive is jetted onto the region of the first surface, wherein the second adhesive has a viscosity lower than a viscosity of the first adhesive. The first surface of the first item and a second surface of a second item are brought into contact with one another. The method also includes curing the first and second adhesives. While the methods can be particularly suitable for manufacturing optical light guide elements, the methods also can be used in other contexts and applications as well.
