This NASA SBIR Phase II proposal presents an unprecedented laser micro additive manufacturing system for making Stirling heat engine regenerators, by using a pulsed fiber laser and beam shaping technology. It is the enabling technology for manufacturing fine structures with micron precision. 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 to NASA during Phase 1. Prototypes in compliant with the Stirling heat engine system requirement will be delivered at the end of Phase II.
In addition to NASA’s heat engine components 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 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$49 billion by the year 2028, driven by the advent of newer technologies, approaches, and applications.
