Abstract Scope |
Fused deposition modeling (FDM) is an extrusion-based additive manufacturing (AM) process, depositing material (typically thermoplastic) as uniform elements. The resulting structure is a tight (or controlled density) lattice of approximately isotropic meso-scale regions with 3-D macro-scale anisotropy; this structure can be designed to produce an easily manufacturable structured when subject to the proper manufacturability constraints. The present study explores various design strategies for laying out the material elements. After the conceptual development and discussion, two case studies will be provided to further demonstrate the concepts. This work will provide a baseline for future studies on AM-driven meso-scale design using other scanning-type AM processes (such as SLA, SLS, and SLM/DMLS) for polymer, metal, and composite materials. |
