In response to the aging infrastructure crisis in the United States, the U.S. Army Corps of Engineers (USACE) has embraced 3D printing technology to address critical maintenance needs. Recently, they achieved a significant milestone by utilizing 3D printing to fabricate a 12-foot-long metal part for the ship arrestor system on the Poe Lock, a vital component of the Soo Locks facility in Sault Ste. Marie, Michigan.
The Poe Lock plays a crucial role in the transportation of domestic iron ore, making its uninterrupted operation essential for the nation’s economic stability. Traditional methods of replacing aging components often entail lengthy lead times and significant costs. However, with 3D printing, the USACE was able to manufacture the replacement part in just 12 weeks, a fraction of the time required by conventional manufacturing methods.
This achievement demonstrates the transformative potential of additive manufacturing in civil engineering. By leveraging 3D printing technology, the USACE was able to expedite the repair process, minimizing disruption to operations at the Poe Lock. The success of this project highlights the collaborative efforts between the USACE, research institutions like the U.S. Army Engineer Research and Development Center (ERDC), and industry partners such as Lincoln Electric.
Looking ahead, the USACE aims to further integrate additive manufacturing into its operations to reduce turnaround times for replacement components and enhance the reliability of critical infrastructure systems. By embracing innovative technologies like 3D printing, the USACE is not only ensuring the longevity of America’s infrastructure but also paving the way for a more resilient and sustainable future.
