Abstract: Additive manufacturing systems (AMS) are disclosed. The AMS may include a movable build platform, and a calibration system operably connected to the build platform. The calibration system may include a reflective element operably coupled to the build platform, a first calibration model positioned above and vertically offset from the reflective element, and a first camera substantially aligned with the first calibration model. The first camera may be visually aligned with the reflective element to capture a first reflective image of the first calibration model as reflected by the reflective element. The calibration system may also include at least one computing device operably connected to the build platform and the first camera, and configured to calibrate the build platform by: adjusting an actual inclination of the build platform in response to determining the first reflective image differs from a predetermined image of the first calibration model.

Abstract: A damaged applicator identifier system for an additive manufacturing (AM) system, and AM system including the same are disclosed. The damaged applicator identifier system may include a damaged applicator identifier determining whether the active applicator is damaged by identifying a non-planar surface in a layer of raw material on a build platform of the AM system after formation of the layer by the active applicator. A damaged applicator controller is configured to cause replacement or repair of the damaged, active applicator in response to the damaged applicator identifier identifying the damaged, active applicator.

Abstract: A component includes a body, and an interface in the body defining a first and second portion of the body made by different melting beam sources of a multiple melting beam source additive manufacturing system during a single build. The component also includes a channel extending through the body. The channel includes an interface-distant area on opposing sides of the interface, each interface-distant area having a first width. The channel also includes an enlarged width area fluidly communicative with the interface-distant areas and spanning the interface, the enlarged width area having a second width larger than the first width. Any misalignment of the melting beams at the interface is addressed by the enlarged width area, eliminating the problem of reduced cooling fluid flow in the channel.

Abstract: An applicator repair system for an additive manufacturing (AM) system, and an AM system including the same are disclosed. The applicator repair system includes a repair device including a repair element configured to repair a damaged applicator element on an applicator of an AM system. The damaged applicator element is configured to distribute a layer of raw material on a build platform of the AM system. The repair device is positioned within a processing chamber of the AM system. A damaged applicator controller may be provided that is configured to cause repair of the damaged active applicator in response to the damaged applicator being identified as damaged.

Abstract: Additive manufacturing systems (AMS) are disclosed. The AMS may include a build platform, and energy emitting device(s) positioned above the build platform. Energy emitting device(s) may be configured to form a test mark directly on a reference surface of the AMS. AMS may also include a calibration system operably connected to the energy emitting device(s). The calibration system may include measurement device(s) configured to determine an actual location of the test mark on the reference surface, and computing device(s) operably connected to the energy emitting device(s) and the measurement device(s). The computing device(s) may be configured to calibrate the energy emitting device(s) by adjusting the energy emitting device(s) in response to determining the actual location of the test mark on the reference surface from a predetermined, desired location on the reference surface.

Abstract: Additive manufacturing systems (AMS) are disclosed. The AMS may include a build plate positioned directly on a movable build platform, and a recoater device positioned above the build plate. The recoater device may include a blade. Additionally, the AMS may include a calibration system operably connected to the recoater device. The calibration system may include at least one measurement device coupled or positioned adjacent to the recoater device, and at least one computing device operably connected to the measurement device(s). The computing device(s) may be configured to calibrate the recoater device by adjusting a height of the blade of the recoater device relative to a reference surface of a component of the AMS in response to determining a pre-build distance between the blade of the recoater device and the reference surface differs from a desired distance. The pre-build distance may be determined using the measurement device(s).

Abstract: A voucher processor (122) receives (204) a plurality of voucher identifiers from a voucher provider (132) and, for each voucher identifier, instructs (208) the issuing of payment credentials of a payment instrument from an issuer processor (123). The issuer processor (123) or the voucher processor (122) links (210) each voucher identifier to payment credentials of a corresponding payment instrument. The voucher processor (122) or issuer processor (123) submits the plurality of voucher identifiers to the voucher provider (132) along with the linked payment credentials for each voucher identifier, such that, subsequent to a voucher being activated (408), the voucher provider is capable of initiating (424) a transfer of funds associated with the voucher in favour of the voucher provider (132) by transmitting the payment credentials linked to the voucher identifier for receipt by the issuer processor (123).

Abstract: Provided are filtration systems, filters, and corresponding methods of installing and using a clean room filter. A filtration system may include a housing defining a vent opening and a filter opening. The housing may include a knife edge disposed about a perimeter of the filter opening and configured to extend downwardly. The filtration system may include a filter removably attached to the housing. The filter may include a frame having an opening and a channel disposed about a perimeter of the opening. The filter may further include a filter substrate disposed in the opening of the frame, a gasket disposed about a perimeter of the opening within the channel, and an adhesive compound disposed within the channel between the gasket and the channel. The filter may be configured to engage the knife edge of the housing, such that air may be configured to pass between the clean room and a duct via the filter.

Abstract: An aircraft light device has a base, a printed circuit board, a reflector and a cover-lens. The reflector is comprised of a number of reflective surfaces connected together to form a spline. Light transducers on the printed circuit board are of two main types, light emitters and light receivers. Light emitters provide light for illumination, while light receivers enable detection of received light. The two transducer types can be used alone or in combination.
