Bayer Polymers (www.bayerpolymers.com) has introduced a new heat-resistant thermoplastic for auto -body panels. Called Triax TP 3161, this PA/ABS has a heat distortion temperature of up to 392 F, so it can withstand e-coat process without a conductive primer. The material has also been designed to offer a higher stiffness and lower CLTE than earlier body panel thermoplastics. Triax 3161 targets fender applications, though it could also see use in rear side panels.
Siemens and Fraunhofer Institute for Laser Technology have achieved a faster production process based on selective laser melting for speeding up the prototyping of big, complex metal parts in gas turbine engines.
