Zusammenfassung:	To provide an additive manufacturing system that suppresses the weight increase of finished parts in a laminated structure of multiple plies that encompass unidirectional reinforcing fibers.SOLUTION: An additive manufacturing system 100 comprises a delivery guide 112 that is movable with respect to a surface 114 and is configured to deposit a segment 120 of a continuous flexible line 106 along a print path 122. The continuous flexible line 106 comprises a non-resin component 108 and a thermosetting-epoxy-resin component 110 that is partially cured, and also comprises a feed mechanism 104 configured to push the continuous flexible line 106 through the delivery guide 112. The system further comprises a cooling system 234 that maintains the thermosetting-epoxy-resin component 110 of the continuous flexible line 106 below a threshold temperature prior to depositing the segment 120 of the continuous flexible line 106 via the delivery guide 112.SELECTED DRAWING: Figure 1 【課題】一方向性強化繊維を包含している複数のプライの積層構造において、仕上がり部品の重量増加を抑制する付加製造システムを提供する。【解決手段】付加製造システム１００は、表面１１４に対して移動可能な供給ガイド１１２を備え、連続可撓性ライン１０６のセグメント１２０を、プリントパス１２２に沿って堆積させるよう構成される。連続可撓性ライン１０６は、非樹脂構成要素１０８と、部分的に硬化されている熱硬化性エポキシ樹脂構成要素１１０とを備え、供給ガイド１１２を通して連続可撓性ライン１０６を押すよう構成された送り機構１０４も備える。更に、供給ガイド１１２を介して連続可撓性ライン１０６のセグメント１２０を堆積させる以前に、連続可撓性ライン１０６の熱硬化性エポキシ樹脂構成要素１１０を閾値温度未満に維持する冷却システム２３４を備える。【選択図】図１
