Abstract: In an example, a compound article comprises an internal support structure generated using additive manufacturing. In some examples the compound article further includes a flexible material enveloping and supported by a portion of the support structure. The flexible material may be representative of a characteristic of a portion of a human or animal body.

Abstract: In an example, a method includes receiving an image indicative of attenuation of radiation by a first object. The method may include deriving object model data for use in generating a second object representing the first object in a radiation environment, using additive manufacturing. In some examples deriving the object model data includes deriving, from the image, a plurality of zones, each associated with a different radiation attenuation level, determining a radiation condition of the radiation environment, selecting, for each zone and based on the radiation condition, an additive manufacturing attribute comprising an additive manufacturing material and/or a material density for each zone, wherein the additive manufacturing attributes are associated with attenuation characteristics and deriving the object model data by combining selected additive manufacturing attributes to specify a plurality of regions of the second object, which, when the second object is generated, correspond to a geometrical configuration of the zones.

Abstract: In an example, a method includes defining, for an interior portion of an object to be generated in additive manufacturing, an imaging characteristic in a radiation environment. In some examples the method further includes deriving object model data for generating the interior portion of the object by determining an amount of a first contrast agent and an amount of a second contrast agent to deposit such that the object generated according to the object model data comprises the defined imaging characteristic apparent in an image of at least a part of the object comprising the interior portion captured in the radiation environment. The first contrast agent and the second contrast agent may have different imaging characteristics in the radiation environment.

Abstract: A mask is described comprising a mask body for covering the nose and mouth of a wearer, and a cushion for sealing against the wearer's face. The cushion depends inwardly from the periphery of the mask body. The mask body and the cushion are formed of an elastomeric material, and the mask body is shaped such that, when the mask is worn by the wearer, the mask body flexes about a median plane.
