An electric machine may have a stator and a rotor including stacked plurality of electrical steel laminations forming a slot including a first end and opposing sides, the first end defined by a bridge extending between electrical steel on opposing sides of the slot, the bridge being located between the first end of the slot and an outer diameter surface of the rotor and beneath the outer diameter surface of the rotor, the bridge forming a base of a channel open at an outer diameter surface of the rotor.

Methods, systems, and devices for a functional cover are described. A removable cover (e.g., a functional cover) for a wearable ring device (e.g., a ring wearable) may include one or more electrical components positioned at least partially within the removable cover. In some cases, the functional cover may wireless connect with the ring wearable. The removable cover may further include a first inductive component within the removable cover, where the first inductive component is configured to wirelessly communicate with a second inductive component of the wearable ring device when the removable cover is in a mounted state on the wearable ring device. The first inductive component of the removable cover may be configured to transfer electrical current, data, or both, between the one or more electrical components of the removable cover and one or more additional electrical components of the wearable ring device.

A three-dimensional printing system for manufacturing three-dimensional articles includes an apparatus, a filtration system, and a controller. The apparatus is a fabrication system that generates ignitable powder dust in an inert atmosphere fluid stream. The filtration system receives the fluid stream and has a plurality of filter units in a parallel arrangement including at least a first filter unit and a second filter unit. The controller is configured to control the filtration unit and to thereby individually operate the plurality of filter units in two states including a filtration state and an oxidation state. When one of the plurality of filter units is operating in the filtration state another of the plurality of filter units is operating in the oxidation state.
