Abstract
A shaping apparatus, a shaping method and a shaped object are provided. The shaping apparatus for shaping a shaped object that is stereoscopic and in which at least one part is colored is provided and includes: inkjet heads which are coloring heads that eject a coloring ink; an inkjet head which is a light reflective material head that ejects a white ink to become a light reflective material; and a controller. The shaped object including a region to be colored is shaped as the shaped object. At least a part of the region to be colored is formed by arranging a plurality of color cells set in advance as a unit of coloring. Each of the color cells includes a reflective core formed of the white ink, and an outer peripheral portion formed of the coloring ink.
Claims10
A shaping apparatus for shaping a shaped object that is stereoscopic and in which at least one part is colored, the shaping apparatus comprising:
- a coloring head that ejects a coloring material as a material of the shaped object;
- a light reflective material head that ejects a light reflective material as a material of the shaped object;
- and
- a controller that controls operations of the coloring head and the light reflective material head,
- wherein the shaped object including a region to be colored, which is a colored region, is shaped as the shaped object,
- at least a part of the region to be colored is formed by arranging a plurality of color cells set in advance as a unit of coloring,
- each of the color cells includes:
- a reflective core which is a part formed of the light reflective material inside the color cell, and
- an outer peripheral portion which is a part that surrounds a periphery of the reflective core, and
- in an operation of forming the region to be colored, the controller causes the light reflective material head to eject the light reflective material to form the reflective core in each of the color cells, and causes the coloring head to eject the coloring material to form the outer peripheral portion in each of the color cells;
- wherein the shaping apparatus shapes the shaped object by layering the material of the shaped object in a layering direction set in advance,
- a scanning driver that causes the coloring head and the light reflective material head to perform a scanning operation of relatively moving with respect to the shaped object being shaped is further disposed,
- the scanning driver causes the coloring head and the light reflective material head to perform, as the scanning operation, at least:
- a main scanning operation of ejecting the material of the shaped object while relatively moving in a main scanning direction orthogonal to the layering direction with respect to the shaped object being shaped, and
- a layering direction scanning of relatively moving in the layering direction with respect to the shaped object being shaped,
- when a direction orthogonal to the main scanning direction and the layering direction is assumed as a sub scanning direction, three voxels of the material of the shaped object are arranged in each of the main scanning direction, the sub scanning direction, and the layering direction in each of the color cells, and
- in each of the color cells, the reflective core is constituted by one voxel of the material of the shaped object.
