“…The results show that a homogeneous distribution is better for localized loading, while stronger radial threads with weaker spiral threads are better for distributed loading. Another inspiration is from red‐bellied woodpecker ( Melanerpes carolinus ) beak as sutured interfaces in nature (Figure h) . In natural suture lines, the interfaces have complex geometries and re‐entrant features.…”

Recent Progress in Biomimetic Additive Manufacturing Technology: From Materials to Functional Structures

Nature has developed high-performance materials and structures over millions of years of evolution and provides valuable sources of inspiration for the design of next-generation structural materials, given the variety of excellent mechanical, hydrodynamic, optical, and electrical properties. Biomimicry, by learning from nature's concepts and design principles, is driving a paradigm shift in modern materials science and technology. However, the complicated structural architectures in nature far exceed the capability of traditional design and fabrication technologies, which hinders the progress of biomimetic study and its usage in engineering systems. Additive manufacturing (three-dimensional (3D) printing) has created new opportunities for manipulating and mimicking the intrinsically multiscale, multimaterial, and multifunctional structures in nature. Here, an overview of recent developments in 3D printing of biomimetic reinforced mechanics, shape changing, and hydrodynamic structures, as well as optical and electrical devices is provided. The inspirations are from various creatures such as nacre, lobster claw, pine cone, flowers, octopus, butterfly wing, fly eye, etc., and various 3D-printing technologies are discussed. Future opportunities for the development of biomimetic 3D-printing technology to fabricate next-generation functional materials and structures in mechanical, electrical, optical, and biomedical engineering are also outlined.

“…All specimens were subjected to in plane normal impact by a rigid body impactor, having a point mass of 2.10 kg, travelling at an initial velocity of 7 m/s, which are the values used in experimental tests of high-grade ballistic armor steel [25]. The results of the bioinspired geometries were compared with a reference solid block of the same material, subject to similar loading conditions.…”

“…Some of these models were subsequently modified to incorporate related features, from other, suitable geometries such as Bouligand structures [14,20,[31][32][33][34] and biological sutures [25]. Bouligand structures were mimicked by orienting each layer of nacre mimetic aluminum plates at a slightly different angle in the plane of the lamina, while sutures were created as jigsaw interlocks between adjacent tablets in the same plane (L3, L4).…”

Biological materials such as nacre, found in mollusk shells and Bouligand structures, found in the armor of many arthropods, exhibit values of toughness that are much higher than their constituent materials. This is achieved via specific arrangements and combinations of natural materials. In all biomimetic studies seen in literature so far, any one type of material alone is chosen for mimicry. The present work aims to create a set of biomimetic designs that incorporate macroscopic features of both nacre and Bouligand structures, so as to achieve toughness amplification in the given material. Finite element analysis (FEA) of relevant geometric designs are initially performed using ABAQUS software and experimental validation of the most promising model (which was found to show a 46.15% improvement over the reference model) is done. The testing method selected for both simulations as well as experiment is the Charpy impact test (ASTM E23).

“…In addition, the subscale, tile-level, geometry design also allows us to tune Poisson's ratio [9,10] and thus fabricate materials exhibiting conventional or auxetic [11,12] behavior. The tiles in assemblies can be connected through jigsaw puzzle interlocks [13], or the modularity concept can serve for optimization and design purposes and the conglomerates can be printed out as monolithic pieces [4]. In this work, the interlocks are not glued together, they utilize only frictional forces to meet the requirement on reasonably stiff contact and non-destructive reassembly.…”

A concept of a planar modular mechanical metamaterial inspired by the principle of local adaptivity is proposed. The metamaterial consists of identical pieces similar to jigsaw puzzle tiles. Their rotation within assembly provides a substantial flexibility in terms of structural behavior, whereas mechanical interlocks enable reassembly. The tile design with a diagonal elliptical opening allows us to vary elastic properties from stiff to compliant, with positive, zero, or negative Poisson's ratio. The outcomes of experimental testing on additively manufactured specimens confirm that the assembly properties can be accurately designed using optimization approaches with finite element analysis at heart.
