摘要： To provide a building method and a building apparatus for building an object having an inconspicuous deposition streak. The building method includes: receiving, from a user, a data on a thickness of a machining allowance added to the object; generating a building data to which a machining allowance having an input thickness is added; generating the object by depositing a building material based on the building data; and polishing a surface of the object.

摘要： A three-dimensional object includes an outer-layer member and an inner structural member. The outer-layer member is a layer to constitute the surface of the three-dimensional object, and includes an inner space. The outer-layer member is made up of a plurality of divided outer-layer pieces formed of build material, which is functional ink ejected from a droplet ejection head and cured. The inner structural member is disposed in the inner space of the outer-layer member and configured to support the outer-layer member.

摘要： An object is created by a more appropriate method when the object is created by combining pieces. A method of manufacturing a product is provided, in which a product 50 for use as a piece is manufactured when a three-dimensional object 40 is created. The product 50 is built by adding layers of an ink. The product 50 includes a surface region 202, an end region 204, and an interior region 206. At least a part of the surface region 202 is formed in a colored state using a coloring ink. At least a part of the interior region 206 is formed as a light-reflective region using a light-reflective ink. At least a part of a portion along an edge portion 210 of the surface region 202 in the end region 204 is formed in a colored state using a coloring ink.

摘要： A building apparatus building a three-dimensional object includes: an inkjet head serving as an ejection head; and a scan driver. The scan driver causes the inkjet head to perform a main scanning operation and a sub scanning operation. In an operation of forming one layer, the scan driver causes the inkjet head to perform the main scanning operation a certain number of times Pn (Pn is an integer equal to or greater than two), for each position of the layer being built, and to form, as the one layer, a layer configured such that a plurality of blocks formed by performing the Pn main scanning operations are arranged in a row in a sub scanning direction. Each of the blocks includes an intermediate region and an end region. The manner of forming the end region in the corresponding block is differentiated between two layers continuously overlapping in the deposition direction.

摘要： A three-dimensional object configured by a plurality of divided parts and having a surface, one portion of the surface is covered with a covering member. The three-dimensional object includes a first divided part as the divided part, which at least one portion of the first divided part is exposed from the covering member; and a second divided part as the divided part and is covered with the covering member. In the three-dimensional object, at least one portion of a joining surface of the first divided part and the second divided part is covered with the covering member.

摘要： To build an object more appropriately. A building apparatus for building an object in three-dimensional includes: an ejection head serving as a head for an object material that eject the object material constituting the object; an ejection head serving as a head for a support material that ejects the support material; and an ejection head serving as a head for a fluid material that ejects the fluid material. In a case of forming a support layer, part of the support layer is formed with the support material, and at least the other part of the support layer is formed with the fluid material.
