The factory server implements several features to streamline the process of fabricating parts using the manufacturing tools. For instance, the factory server can facilitate the design of a part by extracting features from the part request and identifying model files having those features. The factory server can also select an orientation in which to fabricate the part and determine print settings to use when fabricating the part. In addition, the factory server can implement a process to fabricate a three-dimensional part with a two-dimensional image applied to one or more of its external surfaces. Furthermore, the factory server can also generate a layout of multiple part instances on a build plate of a 3D printer so that multiple part instances can be fabricated at once.

  • Patent number: 10766269
    Abstract: In a printer, an accommodating portion accommodates printing agent supplied from a first cartridge. A print execution device prints with the printing agent supplied from the accommodating portion. A processor acquires first information concerning a residual quantity of the printing agent remaining in the first cartridge. The processor acquires second information concerning a preparation of a second cartridge to be replaced with the first cartridge. If the residual quantity is below a reference quantity and if the second information is acquired, the processor allows the print execution device to perform printing under a cartridge removed state where the first cartridge is removed from the mount portion. If the residual quantity is larger than or equal to the reference quantity or if the second information is not acquired, the processor prohibits the print execution device from printing under the cartridge removed state.

  • Patent number: 10737490
    Abstract: A valve type nozzle controls discharge of a liquid by opening and closing a discharge port by a valve element. The discharge port discharges the liquid, and the valve element moves by applying a predetermined voltage to a piezoelectric element. When the predetermined voltage is applied to the piezoelectric element, the piezoelectric element extends and the valve element moves in a direction where the moving mechanism opens the discharge port. This allows the liquid to be discharged. Further, when the application of the voltage to the piezoelectric element is released, the moving mechanism returns to an original shape by which the valve element closes the discharge port to prevent the discharge of the liquid.
