 | New lightweight polymer film can prevent corrosion
MIT researchers have developed a lightweight polymer film that is nearly impenetrable to gas molecules. It could be used as a protective coating to prevent infrastructure from corrosion or to slow the aging of packaged food and medicines. The material's degree of impermeability has never been seen before in any polymer.

 | What is laser peening for metal components?
According to Curtiss-Wright, laser peening (also called laser shock peening) "drives deep plastic strain into a part that creates a high-magnitude residual compressive stress from 1 to 10 mm below the surface." This process involves hitting a part surface with a laser repeatedly through a stream of water, offering designers the ability "to surgically engineer residual compressive stress into key areas of components." Benefits include enhancements to fatigue strength, durability, damage tolerance, and resistance to stress corrosion cracking of critical metallic components.

 | Micro-brakes for precise motion control applications
The ultra-compact 112 Model Electromagnetic Micro-Brakes from Miki Pulley ensure fast response in high-torque, demanding applications. The simple design features a stator with integrated mounting flange, proprietary composite friction liner, and armature complete with ring plate spring and hub. These brakes halt rotation mechanically by utilizing an electromagnetic field to create mechanical friction. With fast response, the brake's armature engages the stator when the coil is energized. A constant-force plate spring transfers torque to the rotating brake body, halting all motion.

| | Videos+: Technologies and inspiration in action | Metal 3D printing: Right at your desktop
From prototyping to tooling or batch production of end-use parts, the Studio System 2 from Desktop Metal brings metal 3D printing to any office, studio, or lab setting. This powder- and laser-free system consists of an easy-to-adopt two-step process: print using pre-bound metal rod feedstock and then sinter. It requires minimal training and operator intervention. Combined with next-gen Separable Supports and a software-controlled workflow, the Studio System makes metal 3D printing simpler than ever. This platform offers more materials than any other metal extrusion 3D-printing system on the market. They include Inconel 625, titanium (Ti64), copper, tool steels, and stainless steels.
