  • 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.

  • Patent number: 10493745
    Abstract: The invention provides a method for height difference measurement between the print heads and a 3D printer using the method. The 3D printer includes a printing module, a contact sensor, a movement sensor and a controller. The controller makes a 3D print head and the contact sensor contact to each other vertically for generating a contact signal, and obtains a first height value according to a vertical movement distance between the printing module and the contact sensor. The controller makes a color head and the contact sensor contact to each other vertically for generating the contact signal, and obtains a second height value according to a vertical movement distance between the printing module and the contact sensor. The controller obtains a height difference between the 3D print head and the color head according to the first height value and the second height value.

  • Patent number: 10457034
    Abstract: A three-dimensional object printer has a controller that operates pluralities of ejectors ejecting drops of different materials having different colors, at least one color of which is white, to produce objects with different levels of color saturation. The controller operates the pluralities of ejectors with reference to a function of a sum of an average number of drops per voxel in each layer, a target value of an average number of drops per voxel of colorants other than white in each layer, and a distance from a closest surface of the object for each material ejected by the ejectors. At a predetermined distance from a closest surface and greater, the controller operates the pluralities of ejectors to form voxels in layers of the object with only clear and white drops. At distances less than the predetermined distance, the number of clear drops increases and the number of white drops decreases.
