Composites Stabilize Diesel Train Engine Enclosures

Ok, so it's jumbled, but that's the point. We've heard so much about the use of composites in the automotive sector and in aerospace, even with large-scale boats and yachts, but not so much in trains. Improved access to more efficient and cost-effective mass transportation is equally as important as alternative energy sources and lightweighting vehicles as part of green energy strategies. This is a cool development. Any big deals yet for the technology?
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.
