Illinois-based Navistar International Corp. has deployed an all-electric delivery truck that was developed with the help of a $39 million grant from the American Recovery and Reinvestment Act. Navistar intends to build 400 of the all-electric trucks at its facility in Elkhart, IN during its first year of production, and the company expects to produce several thousand vehicles per year in the next few years.
The all-electric truck was designed for maximum efficiency and environmental friendliness, producing zero tailpipe emissions. Navistar designed the vehicle to travel 100 miles before a recharge. It is intended primarily for fleets and commercial truck users in congested, urban environments where stop-and-go driving would otherwise consume a large amount of fuel.
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.
