  • Publication number: 20250225271
    Abstract: The technology disclosed allows for leveraging decentralized credentials to achieve bidirectional authentication between two actors leveraging a messaging platform/system, such as email or another text-based system, verifiable credentials (VCs), and secure web endpoints. It empowers one party (“Sender”) to send a message enclosed with a Verifiable Presentation which allows another party (“Recipient”) to authenticate the message's provenance and the identity of the sender. Moreover, the message contains a link to a secure web endpoint, where the recipient can submit a response signed by their own Verifiable Presentation, allowing the Sender to authenticate the identity of the Recipient. In this way, both participants are able to authenticate each other's identities with an additional factor of authentication, with neither participant being required to share a single service.

  • Patent number: 12318997
    Abstract: A nozzle assembly for a printer head of a 3D printer includes at least two conduit portions, with each conduit portion including an interfacing surface having a recessed channel that is non-linear. The recessed channels cooperate with one another to define a serpentine path, in response to the interfacing surfaces of the associated conduit portions being engaged to one another. The serpentine path extends from a feed opening to a discharge opening for moving a filament therethrough. The nozzle assembly further includes a heating element connected to the conduit portions for transferring heat to the filament disposed in the serpentine path to fully melt the filament without caramelizing or burning the filament.

  • Patent number: 12300371
    Abstract: Disclosed is a method for authenticating requestors and granting access to a permissioned blockchain network shared among enterprise entities. A decentralized registry of credentialled users, in which credentialled users guard their own access information by keeping a private key of a public-private keypair enables systems to avoid keeping information of a large number of users in large, vulnerable containers. A further method removes authenticated users seeking to be forgotten from the registry of users and deletes any personally identifiable information of the withdrawing users.

  • Publication number: 20250108563
    Abstract: A process for automatically adjusting print speed in a 3D printer, a system for printing a 3D object, and a method of printing a 3D object. A scaling factor is selected, including a first component for print speed and a second component for print quality, an extrusion nozzle port size is identified, and a maximum volumetric extrusion rate for a filament material and a minimum volumetric extrusion rate for the filament material is identified. An optimized volumetric extrusion rate is calculated from the maximum volumetric extrusion rate, the minimum volumetric extrusion rate, and the scaling factor. An optimized X-Y velocity Vxy of a print head based on the optimized volumetric extrusion rate is calculated. A computer numerical control code is adjusted to include the optimized X-Y velocity Vxy of the print head.

  • Publication number: 20250100077
    Abstract: A wire feed head for directed energy deposition, a system including a wire feed head, and methods of directed energy deposition. The wire feed head includes a collet connected to a housing, an energy emitter connected to the housing, and an energy pathway defined in the housing connected to the energy emitter. The wire feed head also includes a wire feed pathway defined in the collet and an oscillator coupled to at least one of the collet, the energy emitter, and the energy pathway. The method includes feeding a feed wire through a feed pathway in a wire feed head, emitting energy from an energy source, directing the emitting energy towards the feed wire exiting the feed pathway, and oscillating at least one of the feed wire and the emitted energy relative to the other.

  • Publication number: 20250066941
    Abstract: A three-dimensional printer, system, and method for electrodeposition. The three-dimensional printer and system include a deposition anode, a build plate, wherein at least one of the deposition anode and build plate are moveable relative to the other in at least two axes, and a power supply electrically connected to the deposition anode and the build plate. The method includes forming ions of a feedstock in an electrolyte solution, providing an E-field, and transporting the ions in an E-field to a build plate to form a three-dimensional component.
