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.
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
