In the head unit, an openingfor exposing the nozzle surface of an inkjet headand an openingfor exposing the nozzle surface of an inkjet headare formed in a base member, and the width of the openingin the sub scanning direction is set to a width at which the inkjet headcan be arranged at a first positionA where the inkjet headand the inkjet headare arranged at the same position in the sub scanning direction and a second position where the inkjet headand the inkjet headare arranged at positions shifted in the sub scanning direction.

A repairing method for a shaped object includes: preparing a defective portion part to be attached to a defective portion in a repair target shaped object; creating a repair patch which is an attachment member to be attached to at least one part of the repair target shaped object; and attaching the repair patch to cover at least one part of a boundary portion of the repair target shaped object and the defective portion part; where at least one part of the repair target shaped object is colored. The repair patch including a colored layer and an adhesive layer is created using a shaping device capable of shaping a shaped object colored by a layered shaping method, and the colored layer is colored and formed in accordance with a color of a portion covered by the repair patch in a shaped object.

Repairing method for shaped object, shaping system, and manufacturing method for attachment member

A shaping apparatus includes an inkjet head forming one shaped layer by performing multiple main scans of ejecting an ink droplet of a curable ink that cures according to light of a predetermined wavelength toward a shaping table while reciprocating in a main scanning direction; a light source provided at least at one position on a front side in a forward or return direction in the main scan with respect to the inkjet head and irradiating an ink dot formed by the ink droplet with light; and a flattening unit flattening an upper surface of the ink dot. A shaped object is formed by layering the shaped layer. In the shaping apparatus, the ink dot is flatted by the flattening roller in the return movement without completely curing the ink dot by controlling the on/off state or illuminance of the light source during at least one of the main scans.

Shaping apparatus and shaping method

An inkjet printing apparatus includes an inkjet head that moves in a main scanning direction at the time of printing; a filter chamber provided on a path for supplying ink to a nozzle hole (nozzle) in the inkjet head; and a spherical body placed on a head filter in the filter chamber. The spherical body has a diameter φ larger than the mesh of the head filter. The spherical body is disposed on the head filter so as to be rollable by the movement of the inkjet head.
