The Southeast Regional Upkeep Middle (SERMC) has efficiently used 3D printing to fabricate a alternative cooling rotor for an Arleigh Burke-class guided missile destroyer’s chilled water pump. The six-blade element isn’t bought individually by way of the Navy provide system, usually requiring the acquisition of a whole new pump unit.
The SERMC group developed 4 prototypes over two weeks utilizing reverse engineering methods. They started with a low-cost polymer model of the unique aluminum half earlier than coordinating with Fleet Readiness Middle Southeast Detachment Mayport to pick the ultimate materials. The completed element was manufactured utilizing an aerospace-grade thermoplastic recognized for energy, warmth resistance, and flame retardancy.
The price distinction between 3D printing and standard alternative proved vital. A prototype blade price $17.63 to supply, whereas the ultimate blade price $131.21. Changing all the motor by way of conventional procurement would have price $316,544.16.
“Sailors at SERMC are at all times searching for new purposes for 3D printing to develop our capabilities and save time, assets, and cash,” mentioned Capt. Kiah Rahming, SERMC’s commanding officer. “This effort is a testomony to the ingenuity and drive of our group.” The printed element has been operationally examined, licensed, and put in aboard a destroyer. These cooling pump rotors are used throughout all ship sorts within the Navy fleet.
