Parker Hannifin Recreates 3D Printed Parts for WWII Submarine

Northeast Ohio additive manufacturers are involved in many innovative projects across the region, country, and world.

The USS Cod WWII submarine memorial has a periscope display at the entrance for visitors that never had eyepieces or an eye plate. Thanks to the work of Parker Hannifin’s Advanced Manufacturing Learning & Development Center in Macedonia, now it’s fully functional for the first time since 1988.

Parker Hannifin scanned the original eyepieces, and 3D printed several on Parker’s Carbon 3D machine with EPU 40 material. The plate was reverse-engineered & 3D printed on Parker’s EOS M290 out of 15-5 Stainless Steel, with some light machining afterward. Parker is seeking other opportunities to use additive manufacturing to keep the ship “mission ready”.

About the USS Cod WWII Submarine

The USS Cod is a WWII submarine that was commissioned on June 21, 1943, and served in the Pacific theater with distinction. It’s five massive engines were built by General Motors in Cleveland, Ohio.
