Plastic cable producer Igus Inc. has developed a tribologically optimized plastic plain bearing that requires neither oil nor grease as a lubricant. Since they are lubricant-free, no contaminants escape into the environment. The manufacturing of the bearing is also eco-friendly. The amount of oils used in plastics' manufacturing is also very positive in comparison with aluminum and steel production. Energy from 16 quarts of oil is necessary to produce 1 quart of aluminum, 12 quarts for steel. For 1 quart of plastic, only 1.9 quarts of oil is necessary.
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.
