Abstract
Systems and methods are provided for septa for acoustic cells. One embodiment is a method that includes fabricating a septum of a cell of an acoustic panel, by heating a material into a molten material, depositing the molten material to form a lower chamber of the septum that extends vertically upwards and includes an entry, iteratively depositing layers of the molten material, each layer comprising a filament at the entry that includes overhangs with respect to vertically adjacent layers, and forming openings at locations of the overhangs.

- a septum of an acoustic cell, comprising:
- a lower chamber that extends vertically upwards and includes an entry;
- a stack comprising layers of material disposed atop the entry of the lower chamber, each layer of the stack comprises a filament at the entry and includes overhangs with respect to vertically adjacent layers;
- and
- openings that are disposed between the layers at locations of the overhangs and that result from the overhangs extending beyond adjacent layers.
