MIT team creates 3D-printed glass bricks for reusable construction

2024-09-21T12:31:00-04:00

MIT engineers have created 3D-printed glass bricks that could offer a new approach to construction with sustainable and reusable materials. These interlocking bricks, which offer similar strength to concrete, are designed for circular construction, allowing buildings to be disassembled and reassembled at the end of their life cycle.

The team, led by Assistant Professor Kaitlyn Becker and former MIT researcher Michael Stern, developed the glass bricks using a custom 3D printing technology from MIT spinoff Evenline. Made from recycled glass, the bricks are shaped like figure eights and interlock like LEGO pieces, offering flexibility in assembly and disassembly.

In mechanical testing, the glass bricks demonstrated strength comparable to concrete blocks, proving their potential for real-world architectural applications. The team experimented wi...

Engineers develop bone-inspired concrete for stronger structures

2024-09-19T13:33:00-04:00

Inspired by the natural architecture of human bone, engineers at Princeton University have developed a new cement-based material that significantly enhances the toughness of traditional concrete. This innovative material resists cracking and sudden failure, making it a promising solution for more durable and long-lasting architectural structures.

The research, led by Professor Reza Moini and Ph.D. candidate Shashank Gupta from Princeton's Department of Civil and Environmental Engineering, was published in Advanced Materials. The study introduces a unique design that incorporates cylindrical and elliptical tubes within the cement paste. Mimicking the structure of bone, specifically the tubular osteons found in human cortical bone, this design allows the concrete to trap and delay crack propagation. This “stepwise cracking” mechanism absorbs more energy, reducing the likelihood of sudden collapse.

Princeton researchers develop concrete 3D printing method inspired by ancient fish scales

2024-09-05T08:00:00-04:00

Researchers at Princeton University’s Engineering School have developed a method for 3D printing concrete with improved crack resistance. Taking inspiration from fish scales, the team led by assistant professor Reza Moini claims their design increases resistance to cracking by as much as 63% compared to conventional cast concrete.

Princeton’s method drew inspiration from the double-helical structures that form the scales of an ancient fish lineage named coelacanths. The resulting design sees concrete arranged into individual strands, with robotic 3D printing used to weakly connect each strand to its neighbor.

“The researchers used different design schemes to combine many stacks of strands into larger functional shapes, such as beams,” Princeton explains. “The design schemes rely on slightly changing the orientation of each stack to create a double-helical arrangement (two orthogonal layers twisted across the height) in the beams that is key to improving the material’s resistance to ...

UMaine experiments with 3D printed floor panels made from recyclable natural materials

2024-08-10T11:00:00-04:00

The U.S. Department of Energy’s Oak Ridge National Laboratory and the University of Maine are leading interesting new engineering research into floor cassettes made using recyclable natural materials that are strong enough to be used in multi-story buildings. Thanks to experiments at UMaine's cutting-edge Advanced Structures and Composites Center (which previously contributed to our coverage of bio-based 3D printed homes), engineers were able to produce a capable model made from polylactic acid and lumber by-products, such as wood flour.

The SM2ART Nfloor cassette components can be 3D printed in roughly two-thirds the time it takes for a typical floor cassette to be factory assembled, thus saving labor costs. Scott Tomlinson, a structural engineer at the Center, shared: "This technology holds a lot of promise for the future of sustainable buildings." The project came together at the initiative of the SHoP offshoot Assembly OSM.

The work was also recently on display as part of the ...

German researchers discover carbon sequestering concrete additive made from cyanobacteria

2024-07-29T19:37:00-04:00

Researchers from Germany's Fraunhofer Institute have discovered a new bioconcrete solution made using cyanobacteria (formerly known as blue-green algae) that sequesters carbon through a process of photosynthesis. Their work for the “BioCarboBeton” project examined the potential of stromatolites to be used as an additive in traditional concrete mixtures, finding success after mimicking their natural binding processes by using a new technological method.

The project, which aims to scale up production for commercial uses, also found potential applications in insulation material, brick, formwork filling, and even mortar.

Take a look also at similar SOM and Drexel University-led material research for concrete and concrete alternatives that we published in the past year.

University of Chicago researchers create cooling fabric that can block heat from structures in cities

2024-06-24T20:10:00-04:00

Future city dwellers could beat the heat with clothes made of a new fabric that keeps them cool. The textile, made of a plastic material and silver nanowires, is designed to stay cool in urban settings by taking advantage of a principle known as radiative cooling – the natural process by which objects radiate heat into space.

The material was designed by a team of researchers at the University of Chicago led by Po-Chun Hsu, an Assistant Professor of Molecular Engineering. They designed it to block more than half of the radiation from the buildings and the ground. As reported by New Scientist, the material emits heat in the form of infrared radiation into space, while reflecting the sun’s radiation and infrared radiation emitted by surrounding structures, such as buildings and pavement.

The researchers developed a three-layer textile, where the inner layer is made of common fabric, such as wool or cotton, and the middle layer consists of silver nanowires that reflect most radiation. The top layer is made of a plastic material called polymethylpentene, which emits a narrow band of infrared radiation. Outdoor tests found that the material stayed 16ºF cooler than a regular silk fa...

Princeton University researchers develop tougher cement inspired by shells

2024-06-13T14:48:00-04:00

Engineers at Princeton University have developed a new cement composite, inspired by the material found within certain shells, that is 17 times more crack-resistant than standard cement and 19 times more able to stretch and deform without breaking.

The research team was led by Reza Moini, an assistant professor of civil and environmental engineering. In a recently published article in the journal Advanced Functional Materials, the team reported that creating alternating layers of tabulated cement paste and thin polymer can significantly increase the material’s durability.

Often looking towards biology for inspiration in their work on building materials, the researchers were drawn to a natural material called nacre, also known as mother of pearl. The material is produced by some molluscs as an inner shell layer, and it is also the material that pearls are made of. According to the researchers, nacre consists of a hard mineral called aragonite, which are glued together by a soft bio...

ETH Zurich’s 3D printed sculpture oscillates between ‘opaque boundary’ and ‘transparent curtain’

2024-03-14T12:06:00-04:00

ETH Zurich has unveiled a 6.5-foot-tall lightweight shell fabricated from 3D printing.

Named 'Fluid Forms,' and created by the institution’s Digital Building Technologies group, the structure seeks to showcase “an innovative robotic additive manufacturing method that enables the printing of doubly curved thin shells more efficiently.”

Video courtesy Ιoanna.M/YouTube

The design of Fluid Forms was inspired by the Costa minimal surface, which belongs to a family of shapes that minimize area for a given boundary, resulting in a geometry with strong structural properties. In contrast to horizontal plane printing, the fabrication process sees the print paths align to principal curvature directions, which, according to the team, reduces the need for external support and enhances the precision and surface quality of the curved surface.

Production begins on the world’s tallest 3D printed structure

2024-02-16T11:40:00-05:00

Production has begun on a 3D printed tower in Switzerland, which is expected to be the tallest structure of its kind in the world. Named the ‘Tor Alva’ or ‘White Tower,’ the project is currently being fabricated at ETH Zurich, where the first eight columns of the tower’s lower floor commenced 3D printing in February.

Image credit: Hansmeyer/Dillenburger

The columns’ fabrication sees a robot extrude the concrete in 8mm-high layered print paths. In a departure from traditional concrete construction, the 3D printing process means formwork is no longer required, freeing new avenues for the team to experiment with shapes, surface details, and cavities. The tower will also be the first instance of printed concrete being used in a fully structural manner, with steel reinforcement inserted during the robotic production process.

The tower will be constructed in the remote Swiss Alps village of Mulegns, where it will host music and theater performances. At 98 feet (nea...

Researchers use cellulose and algae to create 3D printed architectural material

2024-02-09T13:46:00-05:00

Researchers at Chalmers University of Technology in Sweden have published their study into how materials made from nanocellulose and algae can be used as sustainable architectural materials. The research, conducted in collaboration with the Wallenberg Wood Science Center, “shows how the abundant sustainable material can be 3D printed into a wide array of architectural components, using much less energy than conventional construction methods,” according to the team.

Nanocellulose, molecules consisting of hundreds or thousands of carbon, hydrogen, and oxygen atoms, are already used in biomedicine to 3D print scaffolds for tissue and cell growth but have never been used in an architectural material. The researchers, therefore, mixed nanocellulose fibers and water with an algae-based material called alginate to produce a 3D printable material with architectural uses in mind.

MIT researchers develop rapid 3D printing process with liquid metal

2024-01-30T12:40:00-05:00

News is circulating about a novel method for 3D printing liquid metals that was developed by researchers working at the Massachusetts Institute of Technology (MIT) Self-Assembly Lab.

The invention can print furniture-sized components using molten aluminum and a ceramic nozzle graphite printer. They say their discovery works without re-melting the recycled materials, as is the case with many current technologies. It resembles a small furnace into which book-sized blocks of the material are fed. The technique, called liquid metal printing (LMP), creates material that is durable enough to withstand CNC milling and other steps in the post-design delivery process.

Drexel team uses bacteria to create self-healing concrete

2023-12-29T11:40:00-05:00

A team from Drexel University has published their research into a self-healing system for concrete. The team, operating in the University’s College of Engineering, embedded bacteria in their concrete system that, when activated by water, can repair cracks in the concrete.

Named ‘BioFiber,’ the Drexel system sees a polymer fiber encased in a bacteria-laden hydrogel and a protective, damage-responsive shell. A grid of BioFibers embedded in a concrete structure can improve the system’s durability, prevent cracks from growing, and enable self-healing, according to the research published in the journal Construction and Building Materials.

The team was inspired by the ability of human skin tissue to self-heal, and the ability of vascular systems to help organisms heal their own wounds. The team identified a strain of Lysinibacillus sphaericus bacteria as a bio-healing agent for the fiber, which is found in soil and can produce a stone-like material capable of healing exposed cracks in con...

Architecture's top green projects and sustainability innovations in 2023

2023-12-27T20:28:00-05:00

Wrapping up a year in the wake of the recently concluded COP28 UN climate summit that resulted in, well, mild levels of agreement on the role of fossil fuels, it is possible to sense a slightly increased urgency toward this most pressing planetary issue on a high-minded diplomatic level. As we're quickly approaching the quarter mark of the 21st century, however, much more concrete action and innovation in various sectors of the AEC domain is needed — and is already happening — on the ground level as well, as we have seen in our reporting on Archinect.

Continuing with our 2023 Year in Review series, let's take a look back at some of the story highlights focusing on decarbonization efforts, material research, policy implementation, and successful applications of sustainability principles this year.

ETH Zurich researcher develops 3D printed insulation foam using recycled materials

2023-12-01T11:48:00-05:00

ETH Zurich has published details of new research into lightweight building components produced using 3D printing. Led by doctoral architecture researcher Patrick Bedarf, the Airlements project centers on cement-free mineral foams derived from recycled industrial waste.

Working within the institution’s Digital Building Technologies group led by Professor Benjamin Dillenburger, Bedarf’s project emerged from a doctoral thesis on lightweight insulating construction elements, and how complex shapes could be manufactured with fewer material inputs. Bedarf ultimately deployed a sustainable insulation material produced by the ETH spin-off FenX using recycled industrial waste.

FenX’s mineral foam material is mostly made from fly ash, a waste product from industrial blast furnaces. Bedarf’s process then deploys 3D printing to shape the material into bespoke building parts without the need for formwork, which is traditionally only partly reusable and more time-consuming.

University of Maryland researchers develop 'cooling glass' that can redirect a building's heat into space

2023-11-17T11:54:00-05:00

Researchers aiming to combat rising global temperatures have developed a new 'cooling glass' that can turn down the heat indoors without electricity by drawing on the cold depths of space. The new technology, a microporous glass coating, can lower the temperature of the material beneath it by 3.5 degrees Celsius at noon, and has the potential to reduce a mid-rise apartment building's yearly carbon emissions by 10 percent.

The technology was developed by a research team at the University of Maryland, led by Distinguished University Professor Liangbing Hu in the Department of Materials Science and Engineering. The coating functions by reflecting up to 99% of solar radiation to prevent buildings from absorbing heat. It emits heat in the form of longwave infrared radiation into space. The phenomenon is known as radiative cooling, in which space serves as a heat sink for the buildings.

According to the research team, their glass is more environmentally stable than previous attempts at cooling coatings. The glass can be applied to a variety of surfaces, such as tile, brick, and metal, which makes it scalable and available for wide use. The researchers envision the new material as a key contributor to the solution to climate change due to its potential to reduce a structure’s energy usage and carbon footprint. The team is now working to further test the glass and understand its practical applications.

Coffee grounds can make concrete a little stronger, too, according to a new RMIT study

2023-08-28T11:58:00-04:00

Engineers in Australia have found a way of making stronger concrete with roasted used-coffee grounds, to give the drink-additive a "double shot" at life and reduce waste going to landfills. [...] Published in the Journal of Cleaner Production, the study by RMIT engineers is the first to prove that waste coffee grounds can be used to improve concrete.

The study found that three different coffee ground samples each increased their concrete pour’s compressive strengths by up to 30% once their organic compounds were broken down through pyrolysis. The discovery could go a long way in combatting issues such as food waste and the carbon impact of concrete’s still rampant use as a construction material worldwide. RMIT will follow up with additional mechanical and durability tests on the same samples.

"Our research is in the early stages, but these exciting findings offer an innovative way to greatly reduce the amount of organic waste that goes to landfill," the paper’s co-lead author, Dr. Shannon Kilmartin-Lynch, explained. Discarded PPE may also have a stirring second life in construction, according to a separate study the same team of researchers published last year.

MIT researchers create strong, ultra-light architected materials using kirigami techniques

2023-08-24T14:02:00-04:00

Researchers at MIT have developed a lightweight architected material inspired by the cellular structures found in natural materials such as honeycombs and bones. Produced with techniques borrowed from the Japanese kirigami paper-cutting technique, the strong metal lattices are lighter than cork while also holding customizable mechanical properties.

Using kirigami techniques, the MIT team led by Professor Neil Gershenfeld of the Center for Bits and Atoms has produced plate lattice structures on a larger scale than was previously possible. The structures are described as "steel cork" by Gershenfeld due to their lightweight nature combined with high strength and stiffness.

“To make things like cars and airplanes, a huge investment goes into tooling. This manufacturing process is without tooling, like 3D printing. But unlike 3D printing, our process can set the limit for record material properties,” Gershenfeld said in a statement.
