Abstract
The present invention relates to the use of additive manufacturing as applied to radiation shielding. In particular, additive manufacturing formulations are described which provide shielding for neutron and photon radiation and which can extend the useful operation life of remote sensing devices utilized to conduct surveillance and inspection work where such radiation fields are present.
Claims16
A method for making a radiation shielding component comprising:
- providing a resin material;
- providing a metal selected from W, Pb, Sn or Sb;
- providing B4C;
- combining said resin, metal and B4C and depositing successive layers in a 3D printer to form an additively manufactured component wherein said component provides shielding for both neutron and photon based radiation.

A method for making a radiation shielding component comprising:
- providing acrylonitrile-butadiene-styrene material;
- providing a metal selected from W, Pb, Sn or Sb;
- providing B4C;
- combining said metal and B4C and depositing successive layers in a 3D printer to form an additively manufactured component at a thickness of 0.1 cm to 8.0 cm, wherein said acrylonitrile-butadiene-styrene material is present at a level of 50% (vol.) to 80% (vol.), said metal is present at a level of 1% (vol.) to 30% (vol.), B4C is present at a level of 10% (vol.) to 40% (vol.), wherein said component provides shielding for both neutron and photon based radiation.
