Lightweight filament for 3D printing developed

... Syntactic foams have enabled the deep dive capabilities of underwater vehicles such as Bluefin-21 used in the search of Malaysia Airline flight 370 and construction of James Cameroon's Deepsea Challenger submarine for the Mariana Trench dive. One of the major challenges in developing vehicles for deep sea exploration is the failure of materials at joints. 3D printing can completely eliminate the need for joining panels to construct these vehicles. ... As part of collaborative efforts between the teams, Dr Mrityunjay Doddamani of Mechanical Engineering department, [National Institute of Technology Karnataka, India], and Prof Nikhil Gupta of Tandon School of Engineering, New York University, recently reported the development of a syntactic foam filament that can be used in commercial 3D printers for printing lightweight components.
