In an example, a method includes identifying, by processing circuitry, a feature of less than a threshold size of an object to be generated in additive manufacturing. In some examples the method further includes determining, by processing circuitry, a first density of a print agent to be applied to build material when generating the identified feature of the object based on an intended flexibility of the feature of the object. The method may further include determining, by processing circuitry, a second density of print agent to be applied to build material when generating another feature of the object.

A cleaner includes a cleaner main body, and a suction unit connected to the cleaner main body to suck air containing dust, and provided with a brush assembly brought into contact with a floor, wherein the brush assembly includes a rotating rod rotatable in one direction, a brush portion protruding from an outer circumferential surface of the rotating rod to rotate together with the rotating rod, and a blade erected at the rear of the brush portion in the one direction to be adjacent to the brush portion, and brought into contact with the brush portion during the rotation in the one direction, to prevent foreign substances from getting tangled in the brush portion. This configuration may prevent foreign substances such as hair and the like from being tangled in the brush portion during an operation of the cleaner.

Systems, methods, and new file formats are provided for printing 3D microstructures. In some implementations, a new file format is provided that defines 3D objects by a wireframe model expressed as a collection of wires. Because wires and their parameters are defined within the new file format, objects may be processed more efficiently and quickly to support 3D rendering operations. Such methods may be used to print new articles, such as eyelashes, bushes, swabs and other novel items.

A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the upright handle assembly and adapted for movement across a surface to be cleaned. The surface cleaning apparatus is further provided with a fluid delivery system comprising a fluid dispenser configured to dispense fluid to a brushroll and at least one fluid delivery channel forming a portion of a fluid delivery pathway. The fluid delivery channel can extend adjacent to a portion of the suction nozzle assembly. An interference wiper interfaces with a portion of the brushroll to remove excess liquid from the brushroll.

An oral care implement includes a head portion. The head portion includes one or more tooth cleaning elements. The oral care implement includes a handle portion that may be coupled to the head portion. The handle portion includes a central body having a proximal portion. The proximal portion may be opposite the head portion. The handle portion may include a first appendage extending laterally outwards from a first side of the central body in a first direction and a second appendage extending laterally outwards from a second side of the central body in a second direction opposite to the first direction. The first and second appendages may be angled towards each other to form an obtuse angle therebetween (e.g., when in an unstressed state). The proximal portion of the central body may protrude from a bottom end of the first and second appendages.

A feminine cleaning device or brush for adult women for cleaning their vagina. The feminine cleaning brush includes a handle, a cleaning portion having rings arranged substantially parallel to one another and a groove positioned between adjacent rings. The number of rings being at least 10 and the number of grooves being at least 10. The feminine cleaning brush includes a middle portion positioned between the handle and the cleaning portion and a tapered tip extending from the cleaning portion. The tapered tip is provided for an easier and smoother insertion into the vagina.
