“…Although there are several existing computational methods in the literature for establishing the 3D models of origami structures, they are often restricted to single-layer and zero-thickness origami models. [54][55][56] In general, such conventional modeling methods construct a model by offsetting the surface of the intermediate layer in the structural configuration. However, the Miura-ori metamaterial geometric model is composed of spatial facets with different dihedral angles; [57][58][59] consequently, if the facets are offset using the conventional methods, there will be blends or voids between adjacent facets.…”

Origami‐based metamaterials have widespread application prospects in various industries including aerospace, automotive, flexible electronics, and civil engineering structures. Among the wide range of origami patterns, the fourfold tessellation known as Miura‐ori is of particular attraction to engineers and designers. More specifically, researchers have proposed different 3D structures and metamaterials based on the geometric characteristics of this classic origami pattern. Herein, a computational modeling approach for the design and evaluation of 3D cellular solids with the Miura‐ori metamaterial geometry which can be of zero or nonzero thicknesses is presented. To this end, first, a range of design alternatives generated based on a numerical parametric model is designed. Next, their mechanical properties and failure behavior under quasistatic axial compressive loads along three perpendicular directions are analyzed. Then, the effects of various geometric parameters on their energy absorption behavior under compression in the most appropriate direction are investigated. The findings of this study provide a basis for future experimental investigations and the potential application of such cellular solids for energy‐absorbing purposes.

“…This structural behavior is a great advantage compared to concrete and steel structures. Sewing joints present a great promising future since compared to steel or concrete they present great economic and sustainable advantages [7] . In the case of the project presented, each hexagon is connected through this system (Figure 3).…”

The twenty-first century is one of the most complex in the history of humanity, mainly due to the ecological crisisit is going through. The construction sector generates about 40% of CO2 emissions into the environment; the foregoingshould motivate this sector to seek new alternatives to develop new building practices. Taking these current needs intoaccount, this document classifies and presents a multidisciplinary solution that integrates biology, engineering andarchitecture to develop a new and innovative lightweight timber structure; it divides with a main structure made oftimber and an innovative joint system made of bio-polymers connecting all the panels. Through the study of diatoms,it was able to analyze the bio-morphology of the structure, joints and in particular the geometry since they were theinspiration for the design of this structure that presents an innovative and novel design of structural optimization.Through parametric design and digital fabrication, it was able to create a complex geometry that obtains excellentstructural behavior. This research discusses and explores how materials, geometry led to the optimization of a structureand how new structures can arise, thanks to biology new solutions can be obtained that are completely sustainable,being a clear example of how to combat the effects of the climate change and in a precise way it highlights theadvantages of the bio-design in the architectural design.
