Abstract: A modular transportation system including a transportation module with loading features, and methods of use. The transportation module comprising: a frame member having a front and a rear opposing ends, wherein the front end comprising an overhang member having an overhang portion protruding downwardly below the frame member; the overhang portion having at least one approach wheel; a base member comprising a plurality of ground wheels; a lifting assembly connected between the base member and the frame member; the lifting assembly configured to lift and lower the frame member relative to the base member; and a leg member comprising a leg body and at least one loading wheel; the leg body having a first end and a second end; the first end connected to the frame member; and the loading wheel connected to the second end. A cart and work cells reconfigure the system for specialty purposes.

Abstract: The invention is a system for the in-situ monitoring of additive manufacturing. The system, without pre-calibration of a test sample, utilizes ultrasonic waves to conduct a layer-by-layer analysis of a three-dimensional component as it is being developed on a build plate. Resonant frequencies for each layer is measured and the difference between the resonant frequencies of consecutive layers are calculated to define a baseline frequency. Similarities or differences in baseline frequencies are used to validate the integrity of the layers of the component, and also to determine if structural inconsistencies exists. Based on these determinations, the system decides whether to continue printing or to halt printing.
