Description: This NASA SBIR Phase I proposal presents an unprecedented laser additive manufacturing system for making radiation shielding components, by mixing various powders that effectively shield neutron and gamma radiation. With our successful history in additive manufacturing, this proposal has a great potential to succeed. A proof of concept demonstration were carried out and samples were delivered at the end of Phase 1. Prototypes in compliant with the neutron and gamma radiation shielding requirement will be delivered at the end of Phase II.

Benefits: In addition to NASA’s radiation shield manufacturing, the proposed pulsed laser AM process can also be used in other applications, such as space vehicle, aircraft, and satellite manufacturing. PolarOnyx will develop a series of products to meet various requirements for commercial/military deployments.

3D printing has broad applications from foods, toys to rockets and cars, to medical devices and biomedical instrumentation including surgical and infection control devices, cardiovascular, home healthcare, and other general medical devices. The global market is projected to reach US$44 billion by 2025, driven by the advent of newer technologies, approaches, and applications.
