“…Many FDM materials behave orthotropically, but this material characteristic is often overlooked during the design process. This dynamic uncertainty is stalling the application of AM and FDM for crucial parts within structures [2]. This requires investigation of anisotropic materials whose stiffnesses vary in the x, y, and z directions.…”

“…This requires investigation of anisotropic materials whose stiffnesses vary in the x, y, and z directions. Adkins et al [2] utilized Digital Image Correlation (DIC) to test the effect of varying the internal lattice structure and print orientation of several cantilever beams printed with Acrylonitrile Butadiene Styrene (ABS) and found that the anisotropic behavior of FDM material is significantly affected by the lattice structure orientation of non-solid parts. Printing parameters such as print orientation, nozzle temperature, and print speed for solid benchmark specimens were tested by Attoye et al [1] to determine the Young's modulus through the testing of tensile loading until failure.…”

Structures and parts are increasingly being fabricated using Additive Manufacturing (AM) due to low material waste, ability to quickly generate prototypes, and potential to create complex geometries that would otherwise be difficult or expensive to manufacture. While there are many benefits to using AM processes, the dynamic behavior of the structure is dependent upon the orientation of the construction. This requires investigation of orthotropic materials which have varying material properties in each of the primary Cartesian axes. Some materials, such as the common 3D printing filament Polylactic Acid (PLA), behave orthotropically. Orthotropic materials have often been represented as isotropic materials to simplify numerical models. While such an assumption may be valid in some cases, this study seeks to characterize PLA beams with a tip mass. Experimental PLA beams are printed in the same orientation and have the same external geometry, but the angle of the filament measured from the major axis of the beam varies. The dynamical characteristics are acquired using free and random vibration experiments. The results show that the angle of filament has a significant effect on the damping ratio and natural frequencies of the system.

The Role of Digital Infrastructure for the Industrialisation of Design for Additive Manufacturing

et al. 2022

The use of Additive Manufacturing (AM) can bring opportunities for industry, but several challenges need to be addressed, specifically the digital infrastructure comprising the AM value chain. A combination of a systematic literature review and an industrial use case study concludes that there is low consideration of the digital infrastructure in Design for Additive Manufacturing (DfAM) methods and tools which has a negative impact on the industrialisation of AM. It is therefore recommended that further studies are to be made on how to manage the digital infrastructure in DfAM processes.

The introduction of additive manufacturing (AM), also referred to as 3D printing, has significantly transformed the production of components in various industries. This study includes a comprehensive examination of the dynamical mechanical characterization of materials produced through additive manufacturing technologies. The study revolves around an assessment of the impact of the additive manufacturing (AM) methods on the material characteristics and performance of manufactured components, with a specific focus on their mechanical characteristics under dynamic load scenarios. A comparative examination takes place to bring out the unique mechanical responses of components created through additive manufacturing (AM) in comparison to traditionally manufactured counterparts. In order evaluate characteristics such as stiffness, damping, and fatigue resistance, investigators utilize various experimental techniques, including dynamically mechanical assessment (DMA), vibrating testing, and impact testing. The outcomes of the study reveal significant insights into the interactions between printing parameters, post-processing techniques, particularly material choices, and their impact on the mechanical properties. This study increases the general understanding of the suitability and dependability of additive manufacturing (AM) components in dynamic applications hence facilitating the establishment of enhanced design and manufacturing procedures for aviation, aerospace, automobile, and biomedical uses.
