"A young entrepreneur is using 3D printers to create cheap school campuses in rural Madagascar.

It takes just $40,000 and 18 hours to build a “Thinking Hut,” as they’re called, and founder of the project Maggie Grout is aiming to get the cost even lower before handing the reins over to local professionals.

GNN previously reported on Maggie Grout’s idea in 2021 during the pandemic. It was then that she and a San Francisco architect came up with the idea of making them honeycomb-shaped so that additional modules could be added seamlessly.

And indeed, the first completed campus is called the “Honeycomb.”

Madagascar is one of the most challenging places in Africa to develop, but also the most opportune owing to a lack of any armed conflicts and a government welcoming of foreign workers.

But extreme poverty, lack of infrastructure, terrible roads, and a delicate, priceless natural ecosystem all pose challenges to anyone seeking to implement large-scale development projects.

Instead, Grout brought her 3D printers over in a single shipping container and has now printed a school in the town of Fianarantsoa, a city in south-central Madagascar with 200,000 people.

“From that first project, I really learned how to streamline the logistics,” Grout told Fast Company. “I learned how to put together the supply chain when there’s not a lot of locally available materials. And then I learned how to work in harmony with the local people.”

Local people are the key—lack of institutional presence in rural areas means that almost any economic activity has a foundation built on years of trust between community individuals. When foreigners come in, building trust is often the biggest challenge to getting a project off the ground in Madagascar.

However, from the onset, Grout said she wanted to rely on the locals as much as possible. During the first project, she learned how to best manage a team of cross-cultural partners. She used local people to install traditional windows and doors, and worked with the Madagascar Ministry of Education to bring in teachers.

“We do think through the holistic collateral impacts of what we’re doing,” Grout says. “We’re really just aiming to be a stepping stone for [the community] to be successful on their own… We don’t want them to be dependent on us.”

Her long-term goal is to establish Thinking Huts in many different countries."

Note: A bit older but still good - and still ongoing! This year they started a formal partnership with the Madagascar Ministry of Education and are working on a new campus, The Honeycomb Project.

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a 3D concrete printing method that captures carbon, demonstrating a new pathway to reduce the environmental impact of the construction industry. The innovative method, detailed in the scientific journal Carbon Capture Science & Technology, aims to significantly reduce the carbon footprint of cement -- a material responsible for 1.6 billion metric tonnes of carbon dioxide (CO2) or about eight per cent of global CO2 emissions -- through lower material usage, reduced construction time, and labour requirements. The newly developed 3D concrete printing process involves injecting steam and CO2, captured as the by-products of industrial processes, into the mixing concrete, which then directly incorporates and stores the CO2 in the concrete structure.

I'm dying to know what you do for a living after that vague explanation

it's simple take crushed rocks and mix them together to use them to make better rocks! sometimes i even crush more rocks myself to add to the mix :)

I was a bit disappointed by Container after reading the glowing Eurogamer review about it. There were multiple turns when it seemed like nobody had any good moves, and when one player got a majority of the money while the others were cash-poor, the best strategy was for him to sit on it and not make any new resources. I do like the basic idea, and the three-tiered factory-sells-to-warehouse-sells-to-ships system makes for an interesting economy, but it doesn’t seem to be tuned correctly to avoid tarpits of nothing to do, at least for three players (even though we were using the mechanical “fourth player” auction thing)

It’s possible it’s one of those games which can technically support three players but really only works with 4+ though.

Things don’t always go to plan

Thats okay, there are some things i could have done better, i.e started the shipping process earlier. It has meant that i’ve sadly had to pull out of the little forest land art exhibition. Lessons learned and disappointment all round, however it’s not the end of the world, it’s just /art/

Photo is from the factory in the netherlands that made the design a reality, it’s on its way to me now. And when it arrives it will be the first time i actually get to touch it!! That’s kind of wild ! Art is made and designed by me, and is mine, but it was made by a machine and only the engineers and factory workers got to handle it. It begs the question of ownership, who made it? Me? Jon the engineer that programmed the robot arm? 3DWeber, the company that Jon works for? The robot? Rich who helped finalise and tweek the design?

I drew it, i learned from rich the perimeters of the machine, Jon ‘hit print’ and verified it’s viability. The machine did the work of moving concrete into position, the company helped pack it, the shipping company have it now! En route to London first!

Is it a collective artwork? By 3dweber, Jon, Rich, Zeigler? And me?

How good old mud can lower building costs

New Post has been published on https://thedigitalinsider.com/how-good-old-mud-can-lower-building-costs/

How good old mud can lower building costs

Buildings cost a lot these days. But when concrete buildings are being constructed, there’s another material that can make them less expensive: mud.

MIT researchers have developed a method to use lightly treated mud, including soil from a building site, as the “formwork” molds into which concrete is poured. The technique deploys 3D printing and can replace the more costly method of building elaborate wood formworks for concrete construction.

“What we’ve demonstrated is that we can essentially take the ground we’re standing on, or waste soil from a construction site, and transform it into accurate, highly complex, and flexible formwork for customized concrete structures,” says Sandy Curth, a PhD candidate in MIT’s Department of Architecture who has helped spearhead the project.

The approach could help concrete-based construction take place more quickly and efficiently. It could also reduce costs and carbon emissions.

“It has the potential for immediate impact and doesn’t require changing the nature of the construction industry,” says Curth, who doubles as director of the Programmable Mud Initiative.

Curth has co-authored multiple papers about the method, most recently, “EarthWorks: Zero waste 3D printed earthen formwork for shape-optimized, reinforced concrete construction,” published in the journal Construction and Building Materials. Curth wrote that paper with nine co-authors, including Natalie Pearl, Emily Wissemann, Tim Cousin, Latifa Alkhayat, Vincent Jackow, Keith Lee, and Oliver Moldow, all MIT students; and Mohamed Ismail of the University of Virginia.

The paper’s final two co-authors are Lawrence Sass, professor and chair of the Computation Group in MIT’s Department of Architecture, and Caitlin Mueller, an associate professor at MIT in the Department of Architecture and the Department of Civil and Environmental Engineering. Sass is Curth’s graduate advisor.

Building a structure once, not twice

Constructing wooden formwork for a building is costly and time-consuming. There is saying in the industry that concrete structures have to be built twice — once through the wooden formwork, then again in the concrete poured into the forms.

Using soil for the formwork could change that process. While it might seem like an unusual material compared to the solidity of wooden formwork, soil is firm enough to handle poured concrete. The EarthWorks method, as its known, introduces some additive materials, such as straw, and a wax-like coating for the soil material to prevent any water from draining out of the concrete. Using large-scale 3D printing, the researchers can take soil from a construction site and print it into a custom-designed formwork shape.

“What we’ve done is make a system where we are using what is largely straightforward, large-scale 3D printing technology, and making it highly functional for the material,” Curth says. “We found a way to make formwork that is infinitely recyclable. It’s just dirt.”

Beyond cost and ease of acquiring the materials, the method offers at least two other interrelated advantages. One is environmental: Concrete construction accounts for as much as 8 percent of global carbon emissions, and this approach supports substantial emissions reductions, both through the formwork material itself and the ease of shaping the resulting concrete to only use what is structurally required. Using a method called shape optimization, developed for reinforced concrete in previous research by Ismail and Mueller, it is possible to reduce the carbon emissions of concrete structural frames by more than 50 percent.  

“The EarthWorks technique brings these complex, optimized structures much closer to built reality by offering a low-cost, low-carbon fabrication technique for formwork that can be deployed anywhere in the world,” Mueller says.

“It’s an enabling technology to make reinforced concrete buildings much, much more materially efficient, which has a direct impact on global carbon emissions,” Curth adds.

More generally, the EarthWorks method allows architects and engineers to create customized concrete shapes more easily, due to the flexibility of the formwork material. It is easier to cast concrete in an unusual shape when molding it with soil, not wood.

“What’s cool here is we’re able to make shape-optimized building elements for the same amount of time and energy it would take to make rectilinear building elements,” Curth says.

Group project

As Curth notes, the projects developed by the Programmable Mud group are highly collaborative. He emphasizes the roles played by both Sass, a leader in using computation to help develop low-cost housing, and Mueller, whose work also deploys new computational methods to assess innovative structural ideas in architecture.

“Concrete is a wonderful material when it is used thoughtfully and efficiently, which is inherently connected to how it is shaped,” Mueller says. “However, the minimal forms that emerge from optimization are at odds with conventional construction logics. It is very exciting to advance a technique that subverts this supposed tradeoff, showing that performance-driven complexity can be achieved with low carbon emissions and low cost.”

While finishing his doctorate at MIT, Curth has also founded a firm, FORMA Systems, through which he hopes to take the EarthWorks method into the construction industry. Using this approach does mean builders would need to have a large 3D printer on-site. However, they would also save significantly on materials costs, he says.

Further in the future, Curth envisions a time when the method could be used not just for formworks, but to construct templates for, say, two-story residential building made entirely out of earth. Of course, some parts of the world, including the U.S., extensively use adobe architecture already, but the idea here would be to systematize the production of such homes and make them inexpensive in the process.

In either case, Curth says, as formwork for concrete or by itself, we now have new ways to apply soil to construction.

“People have built with earth for as long as we’ve had buildings, but given contemporary demands for urban concrete buildings, this approach basically decouples cost from complexity,” Curth says. “I guarantee you we can start to make higher-performance buildings for less money.”

The project  was supported by the Sidara Urban Research Seed Fund administered by MIT’s Leventhal Center for Advanced Urbanism.
