3D Printed Metal Filters Protect Circuit Breakers from Explosion | The Cool Parts Show #57

Circuit breakers used in industrial facilities like oil and gas or water treatment plants protect workers and equipment by interrupting power in the event of an overload. But when a breaker does trip in one of these high-voltage circuits, it releases a large amount of energy in the form of hot plasma gas carrying particles of burnt material; filters are necessary to reduce the pressure and temperature of this explosion and to capture any particulate. Schneider Electric previously produced these parts through assembly, but now is offering circuit breakers featuring 3D printed filters. The filters are produced by contract manufacturer GKN Additive, using HP’s Metal Jet platform for binder jet 3D printing. The binder jetting process enabled the complex and compact geometry needed for the application, while also making the parts affordable enough to produce at scale. This episode of The Cool Parts Show brought to you by Carpenter Additive.
