Capacitance-based Nondestructive Evaluation of Three-dimensionally Printed Polymer - (PPT)

摘要

The effects of printing conditions and layer printing sequence on the molecular structure of 3-D printed polymer have been studied for the first time. The study involves out-of-plane and in-plane capacitance measurements and determination of the out-of-plane permittivity. The capacitance measurement may serve as the basis for the monitoring of the 3-D printing process without the use of attached or embedded sensors.
