To provide systems and methods of bead-type additive manufacturing that do not require repeated adjustment of bead-forming parameters to suppress or prevent failure in finished articles.SOLUTION: The manufacturing system includes a printhead 140, at least one profilometer 180, and a control system. The profilometer measures a manufacturing cross-sectional profile of an existing bead 340 of an article to be manufactured. The control system generates manufacturing profile data including the manufacturing cross-sectional profile and continuously compares the manufacturing profile data to reference profile data of a reference article. The control system adjusts one or more bead formation parameters based on the profile comparison and causes the printhead to form new beads according to the bead formation parameters to suppress or prevent failures associated with the formation of new beads.SELECTED DRAWING: Figure 4 【課題】完成品における不良を抑制又は防止するためにビード形成パラメータを繰り返し調整する必要のない、ビードタイプの付加製造のシステム及び方法を提供する。【解決手段】製造システムは、プリントヘッド１４０、少なくとも１つのプロフィルメータ１８０、及び、制御システムを含む。プロフィルメータは、被製造物品の既存ビード３４０の被製造断面輪郭を測定する。制御システムは、被製造断面輪郭を含む被製造輪郭データを生成するとともに、被製造輪郭データを参照物品の参照輪郭データと継続的に比較する。制御システムは、輪郭比較に基づいて、１つ以上のビード形成パラメータを調整し、新たなビードの形成に関連する不良を抑制又は防止するために、プリントヘッドに、ビード形成パラメータに従って新たなビードを形成させる。【選択図】図４
