New polyetheretherketone (PEEK) stock shapes from Quadrant Engineering Plastic Products combine custom color capabilities with PEEK's top-notch properties—including chemical and stress-crack resistance at elevated temperatures and high mechanical strength. Made from Ketron PEEK GF30, a 30% glass-filled material, the new stock shapes are suitable for medical parts that require tight tolerance machining and repeated sterilizations. In laboratory trials, Ketron® PEEK GF30 did not degrade after more than 250 autoclave cycles. Learn more at the website www.quadrantepp.com.
More and more robots are becoming more autonomous all the time. Now Lockheed Martin has completed a demo mission with two completely autonomous robotic vehicles performing resupply, reconnaissance, surveillance, and target acquisition.
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.
