Further, the controller 117 determines the layer and the position where the electronic component 81 is arranged based on the design data 114, and mounts the electronic component 81 on the circuit board 83.
- the circuit board 83 is modeled by the second modeling unit 23, and the attached object 11 to which the electronic device 12 is attached is modeled by the first modeling unit 22.
- a conductor such as a wiring 89, a through hole 91, and a connection terminal 93, there are restrictions on the modeling.
- FIG. 6 shows the difference in the modeling method between the first modeling unit 22 and the second modeling unit 23 of each embodiment.
- the ultraviolet curable resin used by the third printing unit 71 has a lower wettability to the conductor than the ultraviolet curable resin used by the first printing unit 61.
- the wettability referred to here indicates, for example, the affinity of a liquid on the surface of a solid. The higher the wettability, the better the affinity, and the liquid tends to wet and spread on the surface of the solid. On the other hand, when the wettability becomes low, the affinity becomes poor, and the liquid becomes difficult to wet and spread on the surface of a solid.
- the UV curable resin has high wettability
- the UV curable resin discharged onto the wiring 89, the through hole 91, the connection terminal 93, etc. may be spread and spread beyond the position specified in the design data 114. There is. As a result, the continuity of the wiring 89 and the like may decrease, which may lead to a decrease in electrical characteristics. Therefore, as the ultraviolet curable resin used by the third printing unit 71, a resin having a lower wettability is used. As a result, the spread of the ultraviolet curable resin can be suppressed, the shape can be shaped closer to the design data 114, and the electrical characteristics of the conductor can be improved.

- the insulating layer 87 expands, a part of the wiring 89 or the like formed on the insulating layer 87 may expand or crack.
- the ultraviolet curable resin used by the third printing unit 71 a resin having a smaller coefficient of linear expansion is used.
- a resin having a higher glass transition point than the heating temperature when firing by the firing unit 74 may be used. As a result, expansion of the insulating layer 87 during firing can be suppressed, and cracking of the wiring 89 can be suppressed.
- the ultraviolet curable resin used by the third printing unit 71 has higher adhesion to the conductor than the ultraviolet curable resin used by the first printing unit 61.
- the adhesiveness referred to here indicates, for example, the high adhesion of the ultraviolet curable resin to the conductor.
- the adhesion is, for example, the degree of adhesion to the conductor immediately after the ejection when the droplet of the ultraviolet curable resin is ejected onto the conductor such as the wiring 89. In this case, for example, the adhesion can be evaluated by the adhesion force for a predetermined time after ejection.
- the adhesion is the degree of adhesion of the insulating layer 87 to the conductor after the droplets of the ultraviolet curable resin are ejected onto the conductor and cured.
- the adhesion can be evaluated by the adhesion force for a predetermined time after being cured by ultraviolet rays.

That is, the adhesion of the present disclosure is a high degree of adhesion between the ultraviolet curable resin (insulating layer 87), the metal ink, and the conductive resin paste (conductor).
- the conductor arranged on the insulating layer 87 or the conductor arranged in the insulating layer 87 may be peeled off from the insulating layer 87.
- a gap may be formed in a part of the circuit board 83, or a part of the circuit board 83 may be peeled off.

- an ultraviolet curable resin having a low coefficient of linear expansion or the like is used for the entire modeled object 13, the manufacturing cost of the modeled object 13 increases.

- the ultraviolet curable resin used for the electronic device 12 of the present embodiment is an ultraviolet curable resin used for modeling the attached object 11 (an example of the first curable resin of the present disclosure).
- the wettability to conductors such as wiring 89 and connection terminal 93 is low, the coefficient of linear expansion is lower than that of the ultraviolet curable resin used for the electronic device 12, and the adhesion is lower than that of the ultraviolet curable resin used for the electronic device 12. It meets the high-quality conditions.
- the ultraviolet curable resin When the ultraviolet curable resin is ejected onto a conductor formed of metal ink or conductive resin paste, the ultraviolet curable resin may spread and spread, which may deteriorate the conductivity of the conductor. For this reason, the ultraviolet curable resin used for the electronic device 12 is required to have low wettability in order to suppress the spread even when it is applied to a position closer to the design data 114. Further, if the insulating layer 87 expands when the metal ink or the like is heated, the conductor may be cracked or cut. Further, if the adhesion of the ultraviolet curable resin to the conductor is low, the conductor may be peeled off from the insulating layer 87.
- the ultraviolet curable resin used for the electronic device 12 is required to have a low coefficient of linear expansion and high adhesion. As will be described later, by separating the manufacturing process of the circuit board 83 from the manufacturing process of the attached object 11, the above-mentioned restrictions on the ultraviolet curable resin used for the attached object 11 can be relaxed.
- the ultraviolet curable resin used for the electronic device 12 may be an ultraviolet curable resin that satisfies at least one of the above three conditions, and may not satisfy all three conditions.
- the ultraviolet curable resin used for the attached object 11 may be a resin that satisfies the conditions that the color can be easily changed and the molding speed is faster than the ultraviolet curable resin used for the electronic device 12. Therefore, the ultraviolet curable resin used for the attached object 11 has a high degree of freedom of selection because the attached object 11 is a general resin model and does not include a conductor or an electronic component 81.
- the temperature of the metal ink or the like rises in the firing process by the firing unit 74.
- the support material 15 may melt.
- the support material 15 cannot be used in the modeling of the second modeling unit 23.

For example, if the electronic device 12 is expanded by 10 ⁇ m from the design data 114, it is assumed that the mounting portion 11A is also expanded by 10 ⁇ m, and the hole of the mounting portion 11A may be enlarged by 20 ⁇ m.

Abstract
Description
尚、本開示の内容は、3次元造形物の製造方法としての実施に限らず、種々の形態により実施することができる。例えば、本開示の内容は、3次元造形物を製造する製造装置として実施しても有益である。
以下、本開示の内容を具体化した第1実施形態について、図面を参照しつつ詳細に説明する。図1は、本実施形態の電子デバイス製造装置10を平面視した状態を模式的に示す平面図である。図1に示すように、電子デバイス製造装置10は、搬送装置20と、第1造形ユニット22と、第2造形ユニット23と、装着ユニット24と、組立ユニット25と、スキャンユニット26と、制御装置27(図2、図3参照)を備える。それら搬送装置20、第1造形ユニット22、第2造形ユニット23、装着ユニット24、組立ユニット25、スキャンユニット26は、電子デバイス製造装置10のベース28の上に配置されている。ベース28は、平面視において概して長方形状をなしている。以下の説明では、ベース28の長手方向をX軸方向、ベース28の短手方向をY軸方向、X軸方向及びY軸方向の両方に直交する方向をZ軸方向と称して説明する。
上記したように、本実施形態の製造装置10は、第2造形ユニット23で回路基板83を造形し、第1造形ユニット22において電子デバイス12を取り付ける被取付物11を造形する。配線89、スルーホール91、接続端子93のような導体を造形する場合、造形上の制限が生じる。
次に、図4に示す電子デバイス12を取り付けた造形物13の製造工程について説明する。図7は、造形物13の製造工程を示すフローチャートである。尚、図7に示す製造工程の各工程の内容、順番等は、一例である。また、記憶装置119の設計データ114には、例えば、完成時の造形物13をスライスした各層の3Dデータが設定されている。コントローラ117は、CPUで制御プログラム113を実行し、設計データ114に基づいて第1造形ユニット22等を制御することで、図7に示す制御を実行する。
また、上記第1実施形態では、第1造形ユニット22と第2造形ユニット23とは、積層造形法として、ともにインクジェット方を用いたがこれに限らない。例えば、積層造形法としては、光造形法(SLA)、熱溶融積層法(FDM)、粉末焼結積層造形法(SLS)などを採用することができる。以下の説明では、第2実施形態として、第1造形ユニット22で引き下げ式の光造形法を用いる場合について説明する(図6参照)。
