Consider laser welding for applications using electronic components. Other joining methods can shake embedded components, causing damage. Lasers shine through a transmissive material on top, often natural, into an opaque black material that heats up and melts the natural. The bottom piece often contains carbon black to create opacity that absorbs the laser beam. When two black parts are required, a laser-transmissive black dye is used for the top piece. A new glass-filled nylon compound is designed specifically for laser welding. Luvotech J-3/15/LW BK from Techmer Lehvoss LLC, Clinton, Tenn. is a 15% glass-filled nylon 6. Laser welding requires a pair of materials, one transparent to laser energy and the other laser-absorbing. The first commercial application is a black automotive under-hood part. Techmer is also developing laser-weldable PBT.
Why would the biggest connector company in the world design and build the first fully functional 3D-printed motorcycle? To show TE Connectivity's engineers what the technology can really do in making working load-bearing production parts, and free up their thinking when approaching design problems.
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.
