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.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
