Abstract
A method for making a radiation shield includes generating a three-dimensional (3D) model for a metal body to serve as a radiation shield based upon a predetermined radiation stopping thickness for the metal and a predetermined strength based upon the metal and a pattern of voids therein. The method includes performing fused filament deposition to create the metal body having the pattern of voids therein.

A method for making a radiation shield comprising:
- generating within a processor a three-dimensional (3D) model for a metal body to serve as a radiation shield based upon a predetermined radiation stopping thickness for the metal and a predetermined strength based upon the metal and a pattern of spherically shaped voids therein, the 3D model being generated within the processor by,
- inputting values for a) the radiation environment and radiation tolerance levels for any electronic components and circuits to be protected, b) the dimensional values of the radiation shield to be made, and c) the radiation dose rates for a given period of time in the space environment to which the radiation shield will be subjected;
- and
- based upon the inputted values, calculating for the radiation shield a radiation shielding thickness and material having successive sphere void layers and a sphere void spacing, size and lattice configuration in successive layers where the radius of a sphere wall to the outer diameter of the sphere is constant, and applying the radiation shielding thickness and sphere void spacing, size and lattice configuration in the radiation shield to an extrusion pattern;
- and
- performing fused filament deposition based upon the extrusion pattern to create the metal body having the pattern of spherically shaped voids throughout the metal body in a first section that operates as the radiation shield by extruding an extrusion material in successive layers to produce spherically shaped voids having a predefined size, spacing and density and the pattern of the spherically shaped voids relative to the thickness of the extrusion material to impart the predetermined radiation stopping thickness and predetermined strength.
