Look for interesting new technologies to emerge from a recent partnership between Solvay Solexis, Thorofare, NJ and Parkinson, Woonsocket, RI, to produce the first biaxially oriented polyvinylidene fluoride (PVdF) film. The first film was produced in Parkinson’s Marshall & Williams extrusion and orientation lab for a confidential customer. Changes in process settings and hardware accommodated the resin’s narrow processing window. The test was run on a 16-micron finished film. Biax PVdF film has unique properties, including abrasion and corrosion resistance that suit it to harsh applications, such as capacitors.One of the markets could be bilayer films used in lithium-ion batteries. Another could be very lightweight aircraft, such as the Solar Impulse under development in Switzerland. A laminated PVdF film is used for the underside of a 60-meter wing spar made of honeycomb-carbon fibers. An encapsulated photovoltaic system is on top.
According to a new report from BCC Research, PVdF films will grow at a 22 percent annual rate globally through 2015.
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.
