Carbon fiber-reinforced polyetheretherketone (PEEK) is a corrosion-resistant thermoplastic material that is as strong as steel. The material is reinforced with carbon fiber to allow for increased strength properties at elevated temperatures. With a tensile strength of 300,000 psi and operating temperatures of 525F, the carbon fiber-reinforced PEEK prevents galling and seizure.
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.
