US12631415 - 3D-printed support structures for sound suppressors
Sound suppressors are provided. The sound suppressor includes an engagement, attachable to a barrel of a firearm, and one or more baffle structures manufactured by 3D printing and forming a baffle stack. Each baffle structure includes one or more baffles housed within a wall. The baffles are connected to one another and to the wall by one or more supports, which provide for improved structural strength. The supports further define channels between the baffles and the wall, decreasing weight without sacrificing structural strength. The channels are open or sealed to facilitate flow of pressurized gas between chambers defined by the baffles and the wall, the pressurized gas being generated during discharge of the firearm. The pressurized gas decompresses and cools while traveling between the chambers and the channels, thereafter exiting the sound suppressor at a decreased pressure, temperature, and velocity, which may attenuate a noise associated with the discharge.
