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 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.
