Lin Engineering's new 4518 NEMA 17 stepper motors are designed exclusively with the company's patent-pending Signature Series technology and are the new and improved version of Lin's 4118 motors. The 4518 series is available in three different stack lengths starting with the 4518S at 1.34 inch in thickness and the 4518L measuring in at 1.89 inch. Depending on the stack length, these motors are capable of producing up to 83 oz-inch of holding torque. The new series is suggested for use in applications where size is a factor and load capacities are critical to precision system operation. Industries currently benefiting from the features of this motor in their applications are medical, printing, imaging, optical and robotics. Lin's Signature Series was developed to help reduce system resonance and provide overall smooth motion. Depending on the application, using motors with the Signature Series technology may result in up to 50 percent less resonance being produced.
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.
