To provide systems and methods for septa for acoustic cells.SOLUTION: A method of fabricating a septum 100 of a cell of an acoustic panel includes: heating a material into a molten material; depositing the molten material to form a lower chamber 150 in the septum in a manner extending vertically upwards and including an entry 132; iteratively depositing layers 124 composed of filaments of the molten material at the entry, a filament in each layer having overhangs with respect to vertically adjacent layers; and forming openings at locations of the overhangs.SELECTED DRAWING: Figure 1

    【課題】音響セル用のセプタムを製作する方法を提供する。【解決手段】音響パネルのセルのセプタム100を作製する方法は、材料を加熱して溶融材料にし、溶融材料を積層して、セプタムにおける下側チャンバ150を、垂直方向上方に延びるとともに入口132を有するように形成し、溶融材料のフィラメントから成るレイヤ124を入口において繰り返し積層し、その際に、各レイヤにおけるフィラメントが、垂直方向に隣接するレイヤに対する張り出し部を有するようにし、張り出し部の位置に孔を形成する。【選択図】図1
