This Navy SBIR Phase II proposal presents an unprecedented laser additive manufacturing system to make SiC and Al metal matrix composite for package enclosures, by using a pulsed fiber laser. It is the enabling technology for manufacturing high strength radiation shielding enclosure with low mass and radiation resistance. With our successful history in AM and SM processing, this proposal has a great potential to succeed. A proof of concept demonstration has been carried out and samples were delivered at the end of Phase 1. Prototypes in compliant with the SLBM requirement will be developed and delivered at the end of Phase II.
Benefit: In addition to Navys avionics package enclosure 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. Other commercial applications include 3D printing uses various technologies for building the products for all kinds of applications from foods, toys to rockets and cars. The global market for 3D Printing is projected to reach US$52 billion in 2028, driven by the advent of newer technologies, approaches, and applications. Medical devices and biomedical instrumentation. The medical device industry is highly fragmented and consists of surgical and infection control devices, general medical devices, cardiovascular, home healthcare, and other devices.
