3D Printed Microscale Radiation Shielding

State-of-the-art COTS microelectronics are often found to be susceptible to radiation and systems are required to be redesigned with a new electronic piece-part or multiple kilogram metal shielding.These modifications increase weight, size, costs, and schedule to the program. Space Micro will design radiation shields based on our modeling/simulation tools and thenleverage existing commercially available additive manufacturing processes and materials that prints shields of graded atomic number (Z) materials for use as a radiation shield around packaged COTS microelectronic parts.We will demonstrate by analysisa reduction in the components susceptibility to radiation induced failure, such as single-event upsets from protons and X-ray dose-rate upset/ survival.Approved for Public Release | 17-MDA-9395(24 Oct 17)
