Sam Sia, a Biomedical Engineering Professor at Columbia Engineering recently led a team that used biomaterials that can safely be implanted in the body to manufacture microscale-sized machines. Engineers have been studying hydrogels (biocompatible materials) for decades and Sia has used these to make devices that have freely moving, three-dimensional parts. He achieved this by …
Surprise surprise.... (not so much for some), shape matters more than "substance", material properties are still a question of form, just on a different scale. In the words of Stephen Hyde: "Shape determines function, and the energetics of function dictates the optimal structure required".
From the article:
"The new findings show that the crucial aspect of the new 3-D forms has more to do with their unusual geometrical configuration than with the material itself, which suggests that similar strong, lightweight materials could be made from a variety of materials by creating similar geometric features." and "“You can replace the material itself with anything,” Buehler says. “The geometry is the dominant factor. It’s something that has the potential to transfer to many things.”"
"At first glance, this book may appear eclectic. It contains writings from architectural practice in a language and structure based on subjective views and experiences, combined with research contributions based on systematic design investigations of discrete computational systems. Discussions range from an undulating masonry wall at the University of Virginia erected by then-U.S. President Thomas Jefferson to agile robotic manufacturing processes and computational solver strategies based on graph networks. Conversely, the focus of this anthology is expressed directly in the title: bricks and systems. The basis for this theme is the work conducted at the Utzon(x) Research Group at Aalborg University, in combination with the rich tradition and implementation of masonry work in Denmark, which has attracted increasing attention from architectural practitioners and researchers alike. How should one understand this book, with its widely varied yet converging contributions? As stated by German architect Frei Otto, buildings should be understood as auxiliary means—they are not ends in themselves. We believe this book should be understood through the same lens. It connects, rather than concludes, and it aims to illustrate and identify new modes of working in architecture, particularly with regards to brickwork and other complex systems of modular assemblies, whether physical or digital."
Israeli company MICRON3DP is hoping to shatter 3D printing expectations with its innovative glass 3D printer, capable of high resolution printing and layer thicknesses of as little as 100 microns.

Under Magnitude, the most recent permanent structure from MARC FORNES / THEVERYMANY, evolves the studio's invention of a topological-walking stripe-based material…
Alessio Erioli's insight:
"The Origin of Stripes" -- a 2min video on the making off and principles relying behind THEVERYMANY's #UnderMagnitude permanent structure in Orlando.
#TangentialContinuity: continuous skin along direction of forces, connected by tangential overlaps (as opposed to ribs, tabs, folds,...)
#Stripes#MeshWalking: Fornes's invention on "topological-mesh-walking" as a structural stripe-based material system.
#ExtensiveCurvature: maximizing global double curvature to increase structural performance (as demonstrated through the work of the German Architect and Engineer Frei Otto)
#IntensiveCurvature: maximizing double curvature while constraining maximum radii (triggers curling, branching,...) key premise within the work of THEVERYMANY.
#ShellFromShells: Self-supported structure composed of sub-elements yet made of a single continuous surface. (an advanced hybrid model between conventional structural systems based on the dichotomy columns-beams and continuous self-supported shells)
