Oregon Patent of the Month – October 2021

Delta P Design, Inc. are innovators and manufacturers of custom rifle parts including suppressors and accessories. One of these innovations includes a 3D printable multi-baffled firearm suppressor. By 3D printing the device, the cost and time associated with manufacture are significantly reduced without compromising the structure or function in any meaningful way.

A suppressor functions to dampen noise from firing the gun by absorbing heat produced during the high energy release of the projectile. Some traditional designs for these suppressors are known to experience a mirage effect which distorts the sight. Hot air rises off of the hot suppressor creating this mirage and has been overcome in other scenarios by using an insulating wrap over the firearm. The 3D printing allows the entire suppressor to be made of a single piece with centrally aligned baffle chambers. Gas chambers surround each baffle chamber. Delta P has included exhaust gas chambers along the outer housing of their suppressor which helps flow the hot air away from obstructing the operator’s vision.
