The properties of each lattice structure are a function four basic factors, namely the morphology unit cell, its tessellation, relative density, and material properties. recent advancements in additive manufacturing (AM) have facilitated easy manipulation these factors to obtain desired functionalities. This review attempts expound on several such strategies manipulate factors. Several design-based grading strategies, as functional grading, with respect size density manipulation, multi-morphology, spatial arrangement been discussed their link natural occurrences highlighted. Furthermore, special emphasis is given recently designed tessellation deliver multi-functional responses. Each own acts novel material, thereby tuning required subsequent section explores various processing techniques multi-material AM achieve sequential combination multiple materials generates that single cannot achieve. last scope for combining design process unique structures capable catering advanced requirements.

3d-Printed Thermoplastic Polyurethane/Polyvinylidene Fluoride Gradient Stiffness and Hierarchical Cellular Structures with Tailored Energy Absorption Behavior

Published: Jan. 1, 2023

Currently, designing materials and structures is the main means of improving their energy-absorption properties; however, optimization methods based on structural design can only be applied to specific structures. In this study, two energy-absorbing (EASs) are proposed from material system manufacturing method for fabricating gradient stiffness hierarchical cellular structures, respectively. The structure was prepared using different ratios thermoplastic polyurethane (TPU)/polyvinylidene fluoride (PVDF) filaments in locations EAS. exhibited behavior corresponding strength printed material; decreased order low high, thus achieving controlled yield deformation behavior. Hierarchical honeycomb were by combining three-dimensional (3D) printing with supercritical CO2 foaming technology, which facilitated simultaneous formation both centimeter- micron-scale When PVDF content 30%, average size microporous 3 μm, higher efficiencies compared general structure. energy absorption per unit mass values three compression directions 152.75%, 67.33%, 56.91% higher, respectively, than that TPU without foaming. Therefore, TPU/PVDF blends have various applications absorption, personal protection, transportation.
