Abstract
The present invention relates to both a material construction and manufacturing method resulting in low density materials, especially for use as subsea buoyancy and insulation. The products are made by an additive manufacturing process, printing thin layers of a polymer material while leaving voids of precisely predetermined shapes, sizes and distribution, with precisely predetermined thicknesses between the voids. The resulting products provide optimized strength, buoyancy and insulative value with minimal material usage and density.
