In the domain of 3D printing, in situ monitoring has emerged as a crucial tool for ensuring defect-free production in real time. Unlike traditional methods, where human operators can adjust processes as needed, additive manufacturing relies on preset parameters, often leading to errors that go undetected until completion.
“In additive manufacturing, we currently have open-loop systems in which we set parameters and the machine begins manufacturing on its own,” said Michael Presley, a manufacturing engineer at Johns Hopkins Applied Physics Laboratory (APL).
“The machine can lay miles of welds without ever knowing if something goes wrong. By utilizing in situ monitoring technologies, we can spot those errors earlier if they arise and develop more efficient and accurate processes.”
Recognizing the urgency to bolster manufacturing capabilities, particularly in defense sectors like the Navy, collaborative efforts are underway to advance additive manufacturing monitoring technologies. The Navy’s investment of $132 billion in acquiring Columbia-class submarines has highlighted the need for efficient production methods.
To address manufacturing challenges and expedite submarine production, APL recently hosted a working group to discuss the current state of in situ monitoring and outline a roadmap for its implementation in Navy operations. Collaboration between APL, NAVSEA, and various partner organizations highlights the collective effort to propel additive manufacturing forward.
As the Navy navigates the complexities of modern warfare, the integration of in situ monitoring promises to enhance efficiency and reliability in manufacturing processes, ensuring timely delivery of critical assets.
