Abstract Scope |
Understanding the mechanical performance of 3D-printed polymers, especially in the transition from static to dynamic loading, is critical for expanding the industrial viability of fused filament fabrication (FFF) in sectors such as aerospace and biomedical engineering. This work aims to address the knowledge gap surrounding the dynamic mechanical properties of these materials by investigating their frequency-dependent viscoelastic behavior. Using ultrasonic nondestructive evaluation (NDE) along with tensile testing, we assess how the internal heterogeneous layered microstructure and orientation influence the global viscoelastic response of 6 off-the-shelf polymers and polymer composites. The findings will inform predictions of part failure under dynamic loading conditions, providing a more robust framework for FFF in high-performance applications. Common misconceptions regarding the use of ultrasonic NDE in the quantification of elastic properties of polymers are addressed. Most importantly, this work supports the broader adoption of additive manufacturing by enhancing understanding of material behavior beyond static testing conditions. |
