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 3D printed radiation shields based on our modeling/simulation tools and then leverage 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 analysis and radiation testing, a reduction in the component’s susceptibility to radiation induced failure, such as single-event upsets from protons and X-ray dose-rate upset/ survival.
