Abstract
An additive manufacturing process is provided to produce integral 3-dimensional (3D) articles by laminating together a plurality of expanded polytetrafluoroethylene (ePTFE) membranes. The process includes repetitive cycles of ePTFE membrane lamination paired with laser cutting/bonding to produce a desired geometry based on a predefined pattern. The process may be practiced manually or may be configured to work with commercially available LOM machines/systems developed for use with other roll-to-roll processible materials, such as paper.
