“…[54][55][56] These studies drew inspiration from the sturdy, glassy skeletons of marine sponges to create more robust structures. [57][58][59][60] Furthermore, we introduced prebuckling to the basic straight beam, resulting in an compliant tubular version that sets a standard for increasing the maximum torsional resilience inherent in the tubular structure.

Additive manufacturing has proven to be a reliable and quick method for creating devices and tools, particularly during disruptions to supply chains. One example is 3D printed nasal swabs with tubular structures that require robust mechanical strength while maintaining adequate flexibility. However, there is a lack of detailed understanding on the mechanical response of tubular structures under torsion loading. The goal of this work is to understand the torsional behavior of a new group of 3D printed tubular metamaterials. We used the idea of mechanical metamaterials and started with a simple rectangular lattice. Two main design methods were used: reinforced lattices and compliant lattices. First, we added diagonal reinforced beams to enhance the torsional rigidity, inspired by the lattice structure of sea sponges. Furthermore, we added pre‐buckling to the straight beam, creating a flexible structure that increases the maximum torsional resistance. Our experiments demonstrated the sponge‐inspired design exhibits enhanced stiffness approximately 21 times that of baseline tubular designs. Moreover, the strength and toughness of the sponge‐inspired design are approximately 2.5 and 3 times higher, respectively. By curving the straight beam, we created a set of compliant tubulars that improve flexibility. The torsional angle is increased by at least 2.7 times, while the torsional toughness can reach up to 17 times. Numerical simulations have demonstrated that introducing triangulation into the diagonal reinforced lattice can enhance its stiffness and stability. This is achieved by effectively distributing stress, thereby contributing to structural rigidity. By curving a straight beam and constructing a compliant lattice, stresses are more evenly distributed over a larger area, allowing for greater deformation of the beam without causing failure. Using these two design strategies helps in creating tubular metamaterials with varied applications. Industries requiring high torsional resistance, such as aerospace parts and the automotive industry, can particularly benefit from these materials. They also offer advantages for sectors that need enhanced flexibility, like wearable electronics and soft robotics.This article is protected by copyright. All rights reserved.

“…The thick silicon bone needles are at right angles to each other and form a tridimensional lattice with the thin bone needles. [ 40 , 57 , 58 , 59 ] This lattice architecture has received great attention due to its excellent mechanical stability. However, the potential mechanical properties of the hierarchical and multiscale structure of the net‐like lattice architecture still need to be further explored.…”

The natural design and coupling of biological structures are the root of realizing the high strength, toughness, and unique functional properties of biomaterials. Advanced architecture design is applied to many materials, including metal materials, inorganic nonmetallic materials, polymer materials, and so on. To improve the performance of advanced materials, the designed architecture can be enhanced by bionics of biological structure, optimization of structural parameters, and coupling of multiple types of structures. Herein, the progress of structural materials is reviewed, the strengthening mechanisms of different types of structures are highlighted, and the impact of architecture design on the performance of advanced materials is discussed. Architecture design can improve the properties of materials at the micro level, such as mechanical, electrical, and thermal conductivity. The synergistic effect of structure makes traditional materials move toward advanced functional materials, thus enriching the macroproperties of materials. Finally, the challenges and opportunities of structural innovation of advanced materials in improving material properties are discussed.

“…Despite the fact that the combination of triangular and hexagonal hierarchical structures are known to appear in living organisms atthe nano- and micro- (for example, DNA-origami structures [ 41 ] or diatoms frustules [ 1 , 14 , 22 , 42 , 43 , 44 ]) levels, their appearance at the macro-level in Aphrocallistidae glass sponges has not been investigated yet [ 45 ]. Until now, most attention has been focused on material-science-oriented studies of the famous Euplectella aspergillum glass sponge, including the modeling of its geometrically complex skeleton [ 46 , 47 , 48 , 49 , 50 ].…”

Structural bioinspiration in modern material science and biomimetics represents an actual trend that was originally based on the bioarchitectural diversity of invertebrate skeletons, specifically, honeycomb constructs of natural origin, which have been in humanities focus since ancient times. We conducted a study on the principles of bioarchitecture regarding the unique biosilica-based honeycomb-like skeleton of the deep-sea glass sponge Aphrocallistes beatrix. Experimental data show, with compelling evidence, the location of actin filaments within honeycomb-formed hierarchical siliceous walls. Principles of the unique hierarchical organization of such formations are discussed. Inspired by poriferan honeycomb biosilica, we designed diverse models, including 3D printing, using PLA-, resin-, and synthetic-glass-prepared corresponding microtomography-based 3D reconstruction.
