Layer-Paused FFF-Based Manufacturing of PLA-Hemp Composites: Mechanical Behavior and Failure Morphology (2025)

In this study, polylactic acid (PLA)-hemp composite samples were fabricated using a layer-paused fused filament fabrication (FFF) method, in which natural hemp fibers were manually inserted into pre-designed internal channels generated via computer-aided design (CAD). The novelty of this work lies i
