And forming a second member having a second three-dimensional shape by forming a differential shape on the first member using the method.

この構成では、まず、第１部材の第１三次元形状と第２部材の第２三次元形状との差分形状を特定する。次に、特定された差分形状に基づいて、第１部材に差分形状を造形して、第２部材を造形する。このため、第１三次元形状を有する第１部材を使用して、第２部材を造形することができる。   In this configuration, first, a difference shape between the first three-dimensional shape of the first member and the second three-dimensional shape of the second member is specified. Next, based on the specified difference shape, the difference shape is formed on the first member, and the second member is formed. Therefore, the second member can be formed using the first member having the first three-dimensional shape.

Further, the three-dimensional printing apparatus 12 has a function of forming the second member 40 without using the first member 30. The three-dimensional printing apparatus 12 is an apparatus that uses an optical printing method. In the modification, the three-dimensional printing apparatus 12 may be an apparatus using various methods such as a hot-melt lamination method, an inkjet method, an inkjet powder lamination method, a projection method, and a powder sintering method. A photo-curable resin material can be used for the modeling material. In the modification, for example, a metal material or gypsum may be used as the molding material.

図２を参照して、第１部材３０と第２部材４０とを説明する。第１部材３０と第２部材４０とのそれぞれは、樹脂材料から作製されている。なお、変形例では、第１部材３０と第２部材４０とのそれぞれは、例えば、金属材料から作製されていてもよく、石膏から作製されていてもよい。第１部材３０は、第２部材４０の一部が破損した部材である。図２では、第１部材３０の第１三次元形状と第２部材４０の第２三次元形状との違いを理解しやすくするために、第１部材３０において、第２部材４０の第２三次元形状が破線で示されている。第１部材３０の第１三次元形状は、第１部材３０の外部輪郭を表し、第２部材４０の第２三次元形状は、第２部材４０の外部輪郭を表す。なお、外部輪郭とは、第１部材３０や第２部材４０を外部から視ることによって特定される形状を表す。第１部材３０の第１三次元形状は、第２部材４０の第２三次元形状と異なる。第１部材３０の第１三次元形状は、第２部材４０の第２三次元形状の一部が欠損している形状を有する。以下では、第１部材３０の第１三次元形状と第２部材４０の第２三次元形状との差分を、差分形状３２と呼ぶ。第２部材４０は、第１部材３０と差分形状３２とを備える。   The first member 30 and the second member 40 will be described with reference to FIG. Each of the first member 30 and the second member 40 is made of a resin material. In the modified example, each of the first member 30 and the second member 40 may be made of, for example, a metal material or may be made of gypsum. The first member 30 is a member in which a part of the second member 40 is broken. In FIG. 2, in order to make it easy to understand the difference between the first three-dimensional shape of the first member 30 and the second three-dimensional shape of the second member 40, the second tertiary shape of the second member 40 The original shape is shown by a broken line. The first three-dimensional shape of the first member 30 represents the outer contour of the first member 30, and the second three-dimensional shape of the second member 40 represents the outer contour of the second member 40. Note that the external contour represents a shape specified by viewing the first member 30 and the second member 40 from the outside. The first three-dimensional shape of the first member 30 is different from the second three-dimensional shape of the second member 40. The first three-dimensional shape of the first member 30 has a shape in which a part of the second three-dimensional shape of the second member 40 is missing. Hereinafter, the difference between the first three-dimensional shape of the first member 30 and the second three-dimensional shape of the second member 40 is referred to as a difference shape 32. The second member 40 includes the first member 30 and the difference shape 32.

図１に戻り、形状計測装置２０について説明する。形状計測装置２０は、部材の三次元形状を計測する。形状計測装置２０は、三角法方式を利用する装置である。形状計測装置２０は、レーザ光を対象物（例えば、第１部材３０）に照射して対象物から反射するレーザ光をセンサで取得して、対象物の第１三次元形状を計測する。なお、変形例では、形状計測装置２０は、例えば、タイムオブフライト方式及びフェイズシフト方式など、種々の方式を利用する装置であってもよい。   Returning to FIG. 1, the shape measuring device 20 will be described. The shape measuring device 20 measures the three-dimensional shape of the member. The shape measuring device 20 is a device using a trigonometric method. The shape measuring device 20 irradiates a target object (for example, the first member 30) with laser light, acquires laser light reflected from the target object with a sensor, and measures a first three-dimensional shape of the target object. In the modification, the shape measuring device 20 may be an apparatus using various methods such as a time-of-flight method and a phase shift method.

データ処理装置１４は、形状計測装置２０と三次元造形装置１２のそれぞれに通信可能に接続されている。データ処理装置１４は、形状記述部１６と差分特定部１８とを備える。形状記述部１６は、部材の三次元形状を記述する造形データを作成する。形状記述部１６は、例えば、３ＤＣＡＤである。   The data processing device 14 is communicably connected to each of the shape measuring device 20 and the three-dimensional printing device 12. The data processing device 14 includes a shape description unit 16 and a difference identification unit 18. The shape description unit 16 creates modeling data describing the three-dimensional shape of the member. The shape description unit 16 is, for example, 3D CAD.

差分特定部１８は、形状計測装置２０によって計測された三次元形状と、形状記述部１６によって作成された造形データによって記述される三次元形状との差分を特定する。例えば、差分特定部１８は、形状計測装置２０によって計測された第１部材３０の第１三次元形状と、形状記述部１６によって作成された第２部材４０の第２三次元形状とを重ね合わせ、一方から他方を引くことによって差分形状３２を特定する。   The difference specifying unit 18 specifies a difference between the three-dimensional shape measured by the shape measuring device 20 and the three-dimensional shape described by the modeling data created by the shape description unit 16. For example, the difference identifying unit 18 superimposes the first three-dimensional shape of the first member 30 measured by the shape measuring device 20 and the second three-dimensional shape of the second member 40 created by the shape description unit 16. , The difference shape 32 is specified by subtracting the other from the other.

次に、図３のフローチャートを参照して、第１部材３０から第２部材４０を造形する三次元造形方法を説明する。   Next, a three-dimensional forming method for forming the second member 40 from the first member 30 will be described with reference to the flowchart of FIG.

（準備工程）まず、Ｓ２において、作業者は、形状記述部１６を用いて、第２部材４０の造形データを準備する。第２部材４０の造形データには、第２部材４０の第２三次元形状が記述されている。造形データは、データ処理装置１４の図示省略のメモリに格納される。   (Preparation Step) First, in S2, the operator prepares modeling data of the second member 40 using the shape description unit 16. The modeling data of the second member 40 describes the second three-dimensional shape of the second member 40. The modeling data is stored in a memory (not shown) of the data processing device 14.

（計測工程）次に、Ｓ４において、形状計測装置２０内の所定の位置に第１部材３０を配置した後、形状計測装置２０は、第１部材３０の第１三次元形状を計測する。計測済みの第１部材３０の第１三次元形状データは、形状計測装置２０からデータ処理装置１４に送信される。第１部材３０の第１三次元形状データは、データ処理装置１４のメモリに格納される。   (Measurement Step) Next, in S4, after arranging the first member 30 at a predetermined position in the shape measurement device 20, the shape measurement device 20 measures the first three-dimensional shape of the first member 30. The first three-dimensional shape data of the measured first member 30 is transmitted from the shape measuring device 20 to the data processing device 14. The first three-dimensional shape data of the first member 30 is stored in the memory of the data processing device 14.

（差分特定工程）次いで、Ｓ６において、差分特定部１８は、第１部材３０の第１三次元形状と第２部材４０の第２三次元形状との差分形状３２を特定する。具体的には、まず差分特定部１８は、データ処理装置１４のメモリから第１部材３０の第１三次元形状データと、第２部材４０の第２三次元形状を記述する造形データとを取得する。次に、差分特定部１８は、取得済みの第１部材３０の第１三次元形状と取得済みの第２部材４０の第２三次元形状とを重ね合わせ、それらの差分である差分形状３２を特定する。特定済みの差分形状３２は、差分形状３２の三次元形状データとして、データ処理装置１４のメモリに格納される。   (Difference specifying step) Next, in S6, the difference specifying unit 18 specifies a difference shape 32 between the first three-dimensional shape of the first member 30 and the second three-dimensional shape of the second member 40. Specifically, first, the difference specifying unit 18 acquires the first three-dimensional shape data of the first member 30 and the shaping data describing the second three-dimensional shape of the second member 40 from the memory of the data processing device 14. I do. Next, the difference specifying unit 18 superimposes the acquired first three-dimensional shape of the first member 30 and the acquired second three-dimensional shape of the second member 40, and generates a difference shape 32 that is a difference between the two. Identify. The specified difference shape 32 is stored in the memory of the data processing device 14 as three-dimensional shape data of the difference shape 32.

次いで、Ｓ８において、作業者は、第１部材３０を三次元造形装置１２内に配置する。即ち、第１部材３０は、三次元造形装置１２内の造形テーブル（図示省略）上に載置される。   Next, in S8, the operator arranges the first member 30 in the three-dimensional printing apparatus 12. That is, the first member 30 is placed on a modeling table (not shown) in the three-dimensional modeling device 12.

（造形工程）次いで、Ｓ１０において、三次元造形装置１２は、第１部材３０に差分形状３２を造形し、第２部材４０を造形する。具体的には、まず、データ処理装置１４は、メモリに格納されている差分形状３２の三次元形状データから、差分形状３２の断面データ（即ち、造形データ）に変換する。次に、データ処理装置１４は、変換済みの造形データを三次元造形装置１２に送信する。次いで、三次元造形装置１２は、送信された差分形状３２の造形データに基づいて、第１部材３０上に差分形状３２を造形する。具体的には、造形テーブル上の第１部材３０を光硬化性の液体樹脂内に浸漬し、液体樹脂にレーザ光を照射することによって、第１部材３０上に差分形状３２を造形する。これにより、第２部材４０が造形される。   (Modeling Step) Next, in S10, the three-dimensional modeling apparatus 12 models the differential shape 32 on the first member 30, and models the second member 40. Specifically, first, the data processing device 14 converts the three-dimensional shape data of the difference shape 32 stored in the memory into the cross-sectional data of the difference shape 32 (that is, modeling data). Next, the data processing device 14 transmits the converted modeling data to the three-dimensional modeling device 12. Next, the three-dimensional modeling device 12 models the differential shape 32 on the first member 30 based on the transmitted modeling data of the differential shape 32. Specifically, the differential member 32 is formed on the first member 30 by immersing the first member 30 on the forming table in a photocurable liquid resin and irradiating the liquid resin with laser light. Thereby, the second member 40 is formed.

（効果）
上記のＳ６において、形状計測装置２０によって計測された第１部材３０の第１三次元形状と、造形データに記述された第２部材４０の第２三次元形状から差分形状３２が特定される。Ｓ１０において、第１部材３０上に差分形状３２が造形され、第２部材４０が造形される。このため、第１部材３０を使用して、第２部材４０を効率的に造形することができる。この結果、例えば、破損した第１部材３０から第２部材４０を造形することができる。 (effect)
In S6 described above, the difference shape 32 is specified from the first three-dimensional shape of the first member 30 measured by the shape measuring device 20 and the second three-dimensional shape of the second member 40 described in the molding data. In S10, the differential shape 32 is formed on the first member 30, and the second member 40 is formed. Therefore, the second member 40 can be efficiently formed using the first member 30. As a result, for example, the second member 40 can be formed from the damaged first member 30.

（第２実施例）
図４を参照して、第２実施例を説明する。第２実施例では、第１部材１３０は、第１実施例の第１部材３０と異なり、第１部分１３２と第２部分１３６とを備える。第１部分１３２は、第２部分１３６と別体となっており、第２部分１３６と分離している。第１部分１３２は、第１部分１３２を貫通する開口部１３４を有する。開口部１３４については、後で説明する。 (Second embodiment)

In the second embodiment, the first member 130 includes a first portion 132 and a second portion 136, unlike the first member 30 of the first embodiment. The first portion 132 is separate from the second portion 136 and is separated from the second portion 136. The first portion 132 has an opening 134 penetrating the first portion 132. The opening 134 will be described later.

第２部材１４０は、第１部材１３０の第１部分１３２と第２部分１３６とを接続することによって作製される部材である。第２部材１４０において、第１部分１３２と第２部分１３６とは、接合部１４２によって接続されている。即ち、第２部材１４０は、第１部分１３２と、第２部分１３６と、接合部１４２によって構成される。接合部１４２は、第１部分１３２の開口部１３４に配置されている。なお、図４では、接合部１４２の位置を理解しやすくするために、第２部材１４０において、接合部１４２が破線で示されている。接合部１４２は、第１部分１３２の開口部１３４と第２部分１３６の上面とに接続されている。   The second member 140 is a member manufactured by connecting the first portion 132 and the second portion 136 of the first member 130. In the second member 140, the first portion 132 and the second portion 136 are connected by the joint 142. That is, the second member 140 includes the first portion 132, the second portion 136, and the joining portion 142. The joint 142 is disposed in the opening 134 of the first portion 132. In FIG. 4, the joint 142 is indicated by a broken line in the second member 140 so that the position of the joint 142 can be easily understood. The joint 142 is connected to the opening 134 of the first part 132 and the upper surface of the second part 136.

次に、図３のフローチャートを参照して、第１部材１３０から第２部材１４０を造形する三次元造形方法を説明する。なお、第２実施例の三次元造形方法におけるＳ２とＳ８とのそれぞれは、第１実施例の三次元造形方法におけるＳ２とＳ８とのそれぞれと同様であるため、Ｓ２とＳ８との説明を省略する。   Next, a three-dimensional forming method for forming the second member 140 from the first member 130 will be described with reference to the flowchart of FIG. Since S2 and S8 in the three-dimensional printing method of the second embodiment are the same as S2 and S8 in the three-dimensional printing method of the first embodiment, the description of S2 and S8 is omitted. I do.

（計測工程）Ｓ４において、形状計測装置２０は、第１部材１３０の第１三次元形状を計測する。具体的には、まず、形状計測装置２０は、第１部分１３２の第１の部分三次元形状を計測する。次に、形状計測装置２０は、第２部分１３６の第２の部分三次元形状を計測する。そして、第１部分１３２の第１の部分三次元形状と第２部分１３６の第２の部分三次元形状とを結合することによって、第１部材１３０の第１三次元形状を取得する。   (Measurement Step) In S4, the shape measuring device 20 measures the first three-dimensional shape of the first member 130. Specifically, first, the shape measuring device 20 measures a first partial three-dimensional shape of the first portion 132. Next, the shape measuring device 20 measures the second partial three-dimensional shape of the second portion 136. Then, the first three-dimensional shape of the first member 130 is obtained by combining the first three-dimensional shape of the first portion 132 and the second partial three-dimensional shape of the second portion 136.

（差分特定工程）Ｓ６において、差分特定部１８は、第１部材１３０の第１三次元形状と第２部材１４０の第２三次元形状とを重ね合わせ、一方から他方を差引くことで差分形状１４４を特定する。差分形状１４４は、第２部材１４０の接合部１４２の形状となる。   (Difference specifying step) In S6, the difference specifying unit 18 superimposes the first three-dimensional shape of the first member 130 and the second three-dimensional shape of the second member 140, and subtracts the other from one to form the differential shape. 144. The difference shape 144 is the shape of the joint 142 of the second member 140.

（造形工程）Ｓ１０において、三次元造形装置１２は、第１部材１３０に差分形状１４４を造形する。即ち、造形テーブル上に第２部分１３６を載置し、第２部分１３６上に第１部分１３２を配置する。次に、第１部分１３２と第２部分１３６とを液体樹脂内に浸漬し、液体樹脂にレーザ光を照射して接合部１４２を造形する。これにより、第１部材１３０上に接合部１４２が造形され、第１部分１３２と第２部分１３６とが接合部１４２によって接続される。   (Modeling Step) In S10, the three-dimensional modeling apparatus 12 models the differential shape 144 on the first member 130.
