Abstract Scope |
3D printed foams are a growing field of research. Flexible foam structures produced with Fused Filament Fabrication (FFF) present challenges over conventional foams in mechanical durability due to their heterogeneous microstructures, anisotropy, and susceptibility to wear and delamination. This study evaluates the performance of foams fabricated using viscous thread printing (VTP), a process variant that enables controlled porosity and coiling. Based on existing standards, we developed experimental methods to assess abrasive wear resistance, compressive durability, and shear performance of these unique materials. We quantified mass loss and surface degradation under controlled contact conditions. Cyclic compression and shear tests evaluated structural resilience and delamination onset over repeated loading. Results show how density, surface finish, and filament interlayer bonding impact wear resistance and failure modes. The validated methods provide insights into the behavior of foamed FFF materials for applications requiring repeated loading and enhanced service life, such as biomedical and industrial applications. |
