Abstract
Shipboard vibration has been identified as having the potential to cause degradation of 3D printer performance. A proposed mitigation for this effect is to actively monitor vibration of the ship deck and critical parts on the printer. A series of tests are conducted wherein a MIL-STD-810H derived shipboard vibration profile is used to excite a printer while it builds basic test specimens. Response accelerations and pass/fail data are collected from these tests to train a logistic regression model that calculates a predicted likelihood of failure. A demonstration test is used to show the capability to monitor the vibration in real-time, and display a indicator to the operator with a “red-light / green-light” criterion. Results of this demonstration are indicative that the vibration monitoring system provides a reasonable predictive ability, and motivates future testing and real-world deployment on a naval vessel.
