Abstract
A system for thermoforming an object is provided. The system includes a mold and a pressure-box. The mold has a surface that defines a shape of the object and includes two or more portions of differing porosities. The pressure-box is operative to generate a pressure differential across the surface. The two or more portions apply the pressure differential at different loads, based at least in part on the differing porosities, to a material disposed onto the surface so as to form the object by deforming the material into the shape.
