If you break open a chicken bone, you won’t find a solid mass of white material inside. Instead, you will see a complex, spongelike network of tiny struts and pillars, and a lot of empty space. It looks fragile, yet that internal structure allows a bird’s wing to withstand high winds while remaining light enough … Read more
Engineers at MIT are using recycled plastic to 3D-print construction-grade beams, trusses, and other structural components that could eventually provide lighter, modular, and more sustainable alternatives to conventional wood-based framing. They have printed four long trusses from recycled plastic, assembled them into a conventional plywood-topped floor frame, and evaluated the structure’s load-bearing capabilities. The printed … Read more
Microalgae‑based architecture is gaining attention as a sustainable design solution for a variety of uses, and the concept could soon become a reality in Western Australia. Amin Mirabbasi, a PhD student at Murdoch University’s Algae Innovation Hub in Australia, has spent three years designing microalgae filled photobioreactors, which can be incorporated into a variety of … Read more
Scientists at the University of Maryland have turned ordinary wood into a material that rivals steel in strength and weighs far less—and it’s already heading to market. What emerged is now called Superwood, a material created by altering natural wood’s internal structure to boost its strength, reduce weight, and improve resilience. The process, developed and tested … Read more
The Japanese company Lib Work is using earthen materials to 3D print homes. House Model B is a 1,076-square-foot, single-story residence built mainly from earth, lime, and natural fibers. Lib Work says improvements to the overall manufacturing process have lowered its carbon emissions and the building itself is about five times stronger than their previous design … Read more
Scientists have found that recycled glass and lime can strengthen compressed earth blocks. This could be a sustainable alternative to cement for eco-friendly, durable construction materials. Compressed earth blocks are produced by mixing soil with water and compacting the material under high pressure. Cement is commonly added to improve the blocks’ mechanical properties, but its production … Read more
