  • Apparatus and method for performing in-process testing for verification of print parameters in a 3D printing apparatus
    Patent number: 12629894
    Abstract: A 3D printing apparatus and method confirms that one or more print parameters was satisfied in the printing of a 3D object. Sensor readings are obtained during the printing of the 3D object. Based on sensor data corresponding to the sensor readings, a confirmation is made as to whether the one or more print parameters was satisfied in the printing of the 3D object.
    Type: Grant

    Date of Patent: May 19, 2026
    Assignee: MARKFORGED, INC
    Inventors: Bruce David Jones, Edward William Klacza, David Steven Benhaim, Arthur Edward Plummer
  • Secure three-dimensional print files
    Patent number: 12242623
    Abstract: A system is provided for securely performing 3D printing. The system includes: (a) computing equipment configured to: (1) display a list of items available for 3D printing to a user; (2) receive a selection from the user of a particular item; (3) authenticate an acquisition of the particular item by the user; and (4) send, to a 3D printer of the user, a secure 3D print file that includes a description of 3D geometry of the particular item, a description of access restrictions for 3D printing of the particular item, and secure access controls preventing unauthorized access to 3D printing of the particular item; and (b) the 3D printer configured to: (1) authenticate that the user has acquired the particular item and validate that the access restrictions for 3D printing of the particular item do not restrict 3D printing of the particular item by the 3D printer; and (2) in response to authenticating and validating, construct the particular item using the description of 3D geometry of the particular item.
