A part made with crash-optimized Ultramid B3ZG3 CR can withstand static torsion of over 240°C, making it possible to substitute composites for metal in vehicle parts such as steering wheel components, body inserts and seat structures.

Ann, you raise the issue of crash-optimized composites. That got me thinking, how safe is a vehicle if it's designed with this lighter weight material? Beyond safety, what about maintenance costs given that most vehicles are involved in some sort of minor fender bender if not a full-blown accident over the course of their lifetime. Is it much more difficult to repair a composite structure vs. steel door panels, for example?
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
