Abstract: An additive manufacturing system and method for improving the certainty of removing or etching excess substrate from a stack of printed substrate slices to arrive at a 3D object. The approach includes printing a pseudo image as a shell layer around a desired object slice with less polymer (e.g., thermoplastic) material than the 3D object solid layer slice. This slows the etching process when this pseudo image is reached. The pseudo image may be printed to surround the object polymer image on a printed substrate sheet as a shell that provides notice during the excess substrate removal/cleaning process that the desired polymer image is nearby and extra care must be taken to avoid removal of the desired polymer image. The pseudo image may have a 3D patterned surface that can be recognized by a person doing the sandblasting or recognized automatically by an automated 3D object finisher.

Abstract: Techniques are described for applying an edge sealant to the edge of a multi-layer optical device. In particular, embodiments provide an apparatus that performs a precision measurement of the perimeter of an eyepiece, applying the edge sealant (e.g., polymer) based on the precision-measured perimeter, and subsequently cures the edge sealant, using ultraviolet (UV) light that is directed at the edge sealant. The curing process may be performed within a short time following the application of the edge sealant, to ensure that any wicking of the edge sealant between the layers of the eyepiece is controlled to be no greater than a particular depth tolerance. In some examples, the edge sealant is applied to the optical device prevent, or at least reduce, the leakage of light from the optical device, and also to ensure and maintain the structure of the multi-layer optical device.
