  • Patent number: 12011879
    Abstract: Disclosed is a system for depowdering a workpiece formed from a reactive powder by an additive manufacturing process. The system includes a powder removal enclosure, an inert gas source, a sealed ultrasonic transducer, an oxygen sensor, and a controller coupled to the sealed ultrasonic transducer and the oxygen sensor. The controller is configured to perform a plurality of operations including monitoring the oxygen sensor to observe an oxygen level within the powder removal enclosure as an inert gas from the inert gas source displaces a gas environment within the powder removal enclosure, and applying electrical power to the sealed ultrasonic transducer within the powder removal enclosure to ultrasonically remove a residual amount of the reactive powder from the workpiece based on determining that the oxygen level within the powder removal enclosure is below a minimum oxygen level threshold.

  • Patent number: 12005634
    Abstract: In a vat polymerization printer, a beam scanner scans a light beam across a mask and into a tank containing a photo-curable resin. The mask has pixels configurable to be individually transparent or opaque to portions of the light beam, which has a diameter greater than a cross-sectional dimension of the pixels of the mask. During an exposure time duration, a first subset of the pixels are controlled to be transparent at locations corresponding to the cross section of a three-dimensional object to be printed, while a second subset of the pixels are controlled to be opaque at locations not corresponding to the cross section of the three-dimensional object. The beam scanner is controlled to scan the light beam across the mask such that the light beam is always incident on at least one of the pixels of the mask that are controlled to be transparent.

  • Patent number: 12005665
    Abstract: A device for manufacturing a stiffened panel with reinforcements which each have a final thickness and a final height. The manufacturing device includes tools configured to each support a preform of fibers having a U-shaped or C-shaped cross section with a base and two wings. Each tool comprises, at at least one of its first and second lateral faces, a set-back portion which, when two tools are juxtaposed, delimits a recess configured to form a reinforcement during a consolidation or polymerization step. The tools are dimensioned such that each recess has a width, at the consolidation or polymerization temperature, that is substantially equal to the thickness of the reinforcements. This solution makes it possible to more effectively control the geometry of the stiffened panel by avoiding the formation of beads. A method for manufacturing a stiffened panel using the device is also disclosed.
