Abstract Scope |
Additive manufacturing (AM) has enabled the design and development of advanced metamaterials with complex micro/nano structures. Mimicking the nested strengthening mechanisms found in bio-materials can lead to the development of advanced adaptive metamaterials that exhibit high strength under high strain conditions, a property that is not feasible via traditional structural materials and AM methods such as material extrusion and powder bed fusion. This paper studies the feasibility of using Digital Light Processing (DLP) to rapidly manufacture tailored metamaterial lattices with nested strengthening elements. Novel meta-material lattices were printed at different resolutions with minimum feature size varying from 10µ to 100µ. Tensile tests using Digital Image Correlation (DIC) were performed on the lattice structure to understand this new mechanical response by engaging the strengthening elements. Findings from this study presents both design guidelines and mechanical strength of nested metamaterial structures. |
