What do US military planners consider top materials research targets? Well according to the head of the Pentagon’s research arm (the Defense Advanced Research Projects Agency or DARPA) low-cost titanium tops the list. Titanium is in increasing demand for light weight aircraft and stealth-seeking submarines, while its costs are rising and significant amounts of supply are controlled by Russia. One troubling indication is the recent huge supply agreement made between Boeing and Russia’s top titanium provider. DARPA has distributed more than $20 million in grants in efforts to develop lower-cost titanium, as well as material that would have improved fabrication capabilities. DuPont is teaming with a company called MER to explore a technology in which titanium dioxide can be converted into titanium power which can be easily shaped through molding or casting processes.
In his keynote address at the RAPID 2015 conference last week, Made In Space CTO Jason Dunn gave an update on how far his company and co-development partner NASA have come in their quest to bring 3D printing to the space station -- and beyond.
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
