A 3D inkjet printer includes an inkjet head and a medium holder configured to hold a medium having a three-dimensional shape. A Y-axial driving mechanism is capable of moving the inkjet head along a Y-axial. A Z-axial supporting mechanism supports the medium holder so as to be movable along a Z-axial direction. An X-axial driving mechanism is capable of moving the Z-axial supporting mechanism along an X-axial direction. A Z-axial driving mechanism is capable of moving the medium holder along the Z-axial direction. The medium holder includes an A-axial driving mechanism capable of swinging the medium along an A-axial direction. The A-axial direction is a rotational direction about a shaft disposed along the Y-axial direction. A B-axial driving mechanism is capable of rotating the medium along a B-axial direction. The B-axial direction is a rotational direction about a shaft disposed perpendicular to the Y-axial direction.

3D inkjet printer

A printer includes a holding unit, a printer head, a supporting device, a movement controller and a printing controller. The holding unit is configured to hold a print substrate having a surface to be printed. The axes X and Y pass through the print substrate. The movement controller is configured to move the holding unit and the printer head relative to each other in the directions of the axes X, Y and Z which are substantially perpendicular to each other and configured to rotate the holding unit about the axes X and Y relative to the printer head. The printing controller is configured to control ejection of the ink from the printer head according to a relative position of the holding unit and the printer head.

Printer

A three-dimensional printer comprises a base, a first supporting membersupported on the base such that the first supporting member is movable in the direction of an axis X, a second supporting membersupported on the first supporting member such that the second supporting member is movable in the direction of an axis Z, a third supporting membersupported on the second supporting member such that the third supporting member is rotatable about a first rotation axis Yextending in the direction of an axis Y, a holding chuck, for holding a print substrate, supported on the third supporting member such that the holding chuck is rotatable about a second rotation axis X, and a printer headsupported on the baseto extend above the print substratesuch that the printer head is movable in the direction of the axis Y. The movement and rotation of the first through third supporting members and the holding chuck are controlled by a movement controller and the movement of the printer headis also controlled by the movement controller. The ejection of ink from the printer headis controlled by a printing controller according to the movement and rotation control by the movement controller.

Three-dimensional printer

A liquid discharge apparatus includes a nozzle, a pressure chamber, a liquid supply chamber, a liquid supply passage, and a fluid resistance changing mechanism. A liquid pressure in the pressure chamber is configured to be changed to discharge liquid from the nozzle. The liquid supply passage extends in a connecting direction to connect the liquid supply chamber and the pressure chamber. The fluid resistance changing mechanism is configured to change a fluid resistance of the liquid supply passage.

Liquid discharge apparatus and liquid discharge device group capable of changing fluid resistance

A printer includes a holding unit, a printer head, a movement controller and a printing controller. The holding unit is configured to hold a print substrate having a surface to be printed. The printer head is configured to eject ink from a plurality of ejection nozzles to the surface. The movement controller is configured to move the holding unit and the printer head relative to each other. The printing controller is configured to control ejection of the ink from the printer head according to a surface curvature of the surface and a relative position of the holding unit and the printer head.
