Abstract
Systems and methods are provided for building a product by additive manufacturing and creating hollow volumes without including build supports in the hollow volume for the layers above the hollow volume. An additive manufacturing cell includes a material handling device, a printer a material delivery system and an energy source to feed the sheets, print on the sheets, apply a powder on the printed sheets, build a hollow volume into the sheets and consolidate the sheets into a product with a contiguous structure.
