“…One of the principal techniques currently explored to study material formation with micro- and, particularly, macro-scaled textures is 3D-printing, as extensively discussed in recent reviews. − Importantly, the vast majority of efforts are associated with plant-based biopolymers, given their availability at large scales to enable large-area fabrication. Emerging approaches using chitosan − and proteins − are noted. 3D-printing biopolymers can combine efficiently multiscaled forces, as described in Section , with a phenomenology and associated consolidation methods (sol–gel and gels-to-solids) such as those described in Sections and .…”

This review considers the most recent developments in supramolecular and supraparticle structures obtained from natural, renewable biopolymers as well as their disassembly and reassembly into engineered materials. We introduce the main interactions that control bottom-up synthesis and top-down design at different length scales, highlighting the promise of natural biopolymers and associated building blocks. The latter have become main actors in the recent surge of the scientific and patent literature related to the subject. Such developments make prominent use of multicomponent and hierarchical polymeric assemblies and structures that contain polysaccharides (cellulose, chitin, and others), polyphenols (lignins, tannins), and proteins (soy, whey, silk, and other proteins). We offer a comprehensive discussion about the interactions that exist in their native architectures (including multicomponent and composite forms), the chemical modification of polysaccharides and their deconstruction into high axial aspect nanofibers and nanorods. We reflect on the availability and suitability of the latter types of building blocks to enable superstructures and colloidal associations. As far as processing, we describe the most relevant transitions, from the solution to the gel state and the routes that can be used to arrive to consolidated materials with prescribed properties. We highlight the implementation of supramolecular and superstructures in different technological fields that exploit the synergies exhibited by renewable polymers and biocolloids integrated in structured materials.

“…In bioengineering, the motivation to understand the biology of butterflies is derived from the goal to artificially reproduce structural color in chitinous objects. [3,4] Knowing that butterfly scales offer the solution to this, the aim of this study was to determine the basic principles behind this solution, hidden within the multipurpose 'noise' of the color-producing structures.…”

The colorful wings of butterflies result from the interaction between light and the intricate chitinous nanostructures on butterflies’ scales. This study demonstrates that just by reproducing the chitinous ridges present in butterfly scales (i.e., without any other secondary structure), the entire color palette is achieved. This result is achieved using a new methodology based on the controlled reproduction of parts of the biological structure of complex chitinous systems using their native chemistry, enabling the isolation of different features’ contributions. Here the contribution of the ridges and their variations as producing and modulating color hue is isolated. The results suggest that complicated butterfly scales may be non‐ideal solutions for producing color when multifunctionality is not considered.

“…To assess the potential for regionalized manufacturing, we performed a study using urban waste to synthesize FLAM (Sanandyia et al, 2020). Production thus does not need to rely on forestry or coastal regions, because the material can be synthesised at the place of its consumption, which may be even highly urbanized environments (Fernandez and Dritsas, 2020). This does not merely eliminate a substantial amount of energy for transportation (Ng, Song and Fernandez, 2021), but it also provides a new paradigm for circular manufacturing and urban ecology.…”

This paper discusses the design and development of scale masonry structures using robot arms, computer vision hardware and bespoke computational workflows. In parallel to the development of full-scale masonry solutions using a Cable Driven Parallel Robot (CDPR), a faster method for testing large numbers of brick elements is needed to verify buildability, mitigate collisions, and think differently about recycled materials during real-world construction activities. Additionally, by incorporating scanning and analysis technology, materials can be digitized, and their attributes translated into variables for placement within an intended structure.
