Energy-Absorbing Characteristics of an ABS-M30i-based 3D-Printed Periodic Surface and Strut-Based Lattice Structure

Abstract

Abstract: High permeable sandwich structure (foam) or scaffolds are prerequisites in the field of Biomedical, Aerospace, and Automotive sector, due to its energy-absorbing characteristics and tissue formation or cell generation properties. The architecture was previously distant to manufacture but is now feasible, thanks to Additive manufacturing methodology or 3D-printing technology. Fused deposition technology is a method of 3D printing to fabricate the complex shapes and prototypes for large-scale real-world applications. The purpose of this study is to use theoretical and experimental methods to compare the structural strength of three distinct lattice designs at 0.001 S-1 strain rates. The body centered cubic (BCC), Schwarz primitive (TPMS based Design), and simple cubic-double ring lattice (SC-DRL) are investigated using a combination of mechanical compressive testing and finite element analysis (FEA). We evaluate the stress–strain graph, elastic modules, breakdown strengths, deformation methods, and predicted stress distributions of these lattice configurations under compressive pressure force, as well as to assess the structure for load capacity behavior at post-yielding phases depending on its lattice design to accurately represent the behaviors of 3D-printed polymeric crystal lattice structure composed of Acrylonitrile Butadiene Styrene (ABS-M30i) material. The Finite Element Analysis models are designed to describe the compressive deformation performance of three distinct lattices. Such simulations are employed to realize as well as deliver accurate data on failure causes as well as the interaction between the different layers for the compressive deformations and lattice architectures. The influence of three distinct lattice models on the experimental mechanical performance of ABS-M30i specimens produced using FDM, each with a different porosity and structural design, are explored in this research. The finding shows that the finite element analysis derived compressive behavior closely fits the experimental results, as well as the structural behavior, that the strain and plastic dissipation energy are not distributed uniformly throughout each layer.
