A Sustainable Nanocellulose-Based Material Has Been Developed for Construction 3D Printing

Sustainable materials are increasingly in the spotlight as both companies and research teams try to find more eco-friendly alternatives for different industries. One of the sectors that places most emphasis on this quest for sustainability is the construction industry. This is because the emissions of this sector alone are some of the highest worldwide. Annually, the construction sector consumes 50% of the total global fossil resources consumed in the world, generates 40% of all global waste, and causes 39% of global CO2 emissions. This is why the search for an environmentally friendly material for construction has been so important. Now, it could be a reality with a 3D printed hydrogel that could be a greener, architectural material.The new material for more eco-friendly construction comes from a team of researchers from Chalmers University of Technology in Sweden and the Wallenberg Wood Science Center. More specifically, the material is a 3D printed hydrogel made of nanocellulose and algae. Nanocelluolose, for those who may be less aware of it, is a well-known biomaterial and is already extensively used in the field of biomedicine as a way to 3D print scaffolds for tissue and cell growth. However, this would mark the first time it was used in architecture.The univeristy where they have developed this 3D printed sustainable hydrogel material made out of nanocellulose for constructionTo use the material, it must be dried, made possible thanks to the addition of a third material to the original mixture of nanocellulose and water. Alginate, a material composed of algae, was the key to developing the hydrogel, as it gave the dried mixture the flexibility it needed to be used as a building materialThe author of the Chalmers University of Technology study conducted by this research team, Malgorzata Zboinska, explained: “For the first time we have explored an architectural application of nanocellulose hydrogel. Specifically, we provided the so far missing knowledge on its design-related features, and showcased, with the help of our samples and prototypes, the tuneability of these features through custom digital design and robotic 3D printing.”The nanocellulose used in the hydrogel can be sustainably sourced from multiple locations in nature and is a clearalternative to plastic. For within the eco-friendly materials that can stand up to plastic, nanocellulose is the most abundant. “The nanocellulose used in this study can be acquired from forestry, agriculture, paper mills and straw residues from agriculture. It is a very abundant material in that sense,” commented Malgorzata Zboinska.She added: “3D printing is a very resource efficient technique. It allows us to make products without other things such as dies and casting forms, so there is less waste material. It is also very energy efficient. The robotic 3D printing system we employ does not use heat, just air pressure. This saves a lot of energy as we are only working at room temperature.”Photos taken from the study conducted by Malgorzata A. Zboinska.The main uses of the material range from partitions, blinds or panels, to wall coverings for buildings or tile cladding. And though right now the future of this material is uncertain, it is certainly also promising.

Printing Swedish houses with algae

For the first time, a new material made from tiny cellulose fibers and algae has been tried as a more environmentally friendly option for construction.
Researchers from Chalmers University of Technology and the Wallenberg Wood Science Center in Sweden experimented with this sustainable material and found it can be used to create various architectural components using less energy than traditional methods.
The construction industry is a major contributor to global pollution, using half of the world’s fossil fuels, generating 40% of waste, and producing 39% of carbon dioxide emissions. To combat this, scientists are exploring biomaterials like nanocellulose, which is already used in biomedicine for its ability to be 3D printed into structures for tissue growth. This study marks the first attempt to use dried nanocellulose in architecture.
By mixing nanocellulose fibers with water and an algae-based substance called alginate, the researchers created a material that could be 3D printed. This blend provided flexibility to the material when it dried, enabling its use in architectural applications.
The use of 3D printing in architecture is seen as a resource-efficient method. Unlike traditional methods that produce waste, 3D printing requires fewer materials and less energy, particularly when using a robotic system that operates at room temperature. The properties of the nanocellulose hydrogel allow it to be easily printed and maintain its shape without requiring high temperatures.
The researchers tested various printing techniques to understand how the material behaves when dried in different shapes. These dried shapes could be used to create lightweight architectural elements such as room dividers, blinds, wall panels, and coatings for existing building components.
This study lays the groundwork for further exploration of nanocellulose in architectural design, highlighting the need for new approaches to incorporate biobased materials into buildings. Understanding the properties and design possibilities of these materials is crucial for creating sustainable and aesthetically pleasing structures that align with the goals of a circular economy.

Researchers develop eco-friendly hydrogel material for 3D printing in construction

Researchers at Chalmers University of Technology in Sweden and the Wallenberg Wood Science Center have developed a new, sustainable material for use in construction. Made of nanocellulose and algae, the hydrogel material can be 3D printed into a variety of architectural components, using much less energy than conventional construction methods.
The construction industry is responsible for 40% of global waste and 39% of global carbon dioxide emissions. The new material offers a more environmentally friendly alternative to traditional building materials, which are designed to last for hundreds of years and often contain non-renewable resources.
The nanocellulose used in the hydrogel can be acquired from forestry, agriculture, paper mills, and straw residues from agriculture. The material has been extensively used in biomedicine in the past, but it has never been dried and used as an architectural material before.
The energy-efficient process relies on the shear thinning properties of the nanocellulose hydrogel, which liquifies under pressure, allowing it to be 3D printed. The researchers have also designed different toolpaths in the robotic 3D printing process to see how the material would behave when it dried in different shapes and patterns.
The new material opens up new possibilities for architects and designers to create a range of architectural standalone components, such as lightweight room dividers, blinds, and wall panel systems. It could also be used to coat existing building components such as tiles to clad walls, acoustic elements for damping sound, and combined with other materials to clad skeleton walls.
According to Malgorzata Zboinska, lead author of the study, “Design researchers and architects are now intensely searching for ways of designing products made from these materials, both for function and for aesthetics.” The new material is a significant step in the transition to a greener future in line with the European Green Deal, which calls for more resource-efficient buildings and elevated reuse and recycling of materials.
The researchers hope that the new material could be scaled up for use in larger construction projects in the future.

Why this 3D-printed house could be a gamechanger

In this episode of Living Planet, we’re delving into a story about a remarkable 3D-printed house in the US state of Maine. It was made of 100% bio-based materials, which is good news for the construction sector, which accounted for nearly 40% of energy and cross-related CO2 emissions in 2021, according to the United Nation’s Environment Program.But this story is about much more than technology and innovation. Maine is one of the US states that has become a magnet for Americans searching for affordable houses in the wake of the pandemic. It’s also a state that’s seen its once booming paper industry dwindle to a handful of papermills, leaving a glut of sawdust from the timber industry with nowhere to go.

And as it turns out, a research team at the University of Maine was working on another project that turned out to be part of the solution to both of these problems.

In this episode, we speak with Mark Wiesendanger, director of development at MaineHousing; Habib Dagher, the executive director of the Advances Structures and Composites Center at the University of Maine; and Dr. Halil Tekinalp of the Department of Energy’s Oak Ridge National Laboratory.

Press Release – Game-Changer in Additive Manufacturing: Mixed on Site Carbon Neutral Alternative to Cement Unveiled

10/07/2023: Additive manufacturing company, Hive3D Builders, has developed a remarkable mixed on site carbon-neutral and stronger alternative to traditional cement. The printing material, which substitutes the mortar normally used in 3D concrete printing, is able to reduce construction’s CO2 emissions by 93%. Hive3D Builders is currently using this sustainable material to produce over 200 near-net-zero homes. This substance makes the already eco-friendly practice of additive manufacturing even more sustainable and is poised to revolutionize global construction.

Polluting Construction
The construction industry has long grappled with environmental challenges. Traditional concrete production contributes to 8% of global greenhouse gas emissions. 3D concrete printing technology generally has a lower carbon footprint than conventional building methods, mainly due to lower material usage, as well as a lower waste production rate. Along with the eco-friendly technology, additive manufacturing companies often strive to innovatively find sustainable solutions. An example of this is the manufacturer of Hive3D Builders’ printers, CyBe Construction. In the early days of 3D concrete printing, CyBe developed its own eco-friendly building material by using material that has up to 32% less CO2 emissions. Additionally, the material has the possibility to be produced locally.

Carbon-Neutral Material
Hive3D Builders (www.hive3dbuilders.com) take the production of eco-friendly building material one step further. By working with Eco Materials and Green Cement, they managed to develop a low-cost geopolymer cement replacement that has up to 93% less CO2 emissions. Due to geopolymer’s environmentally friendly properties, the substitute for the mortar that 3D concrete printing traditionally uses is almost completely carbon-neutral. Geopolymers have gained attention as a sustainable building material because they require less energy and produce fewer carbon dioxide emissions compared to traditional cement production. They can also utilize industrial waste materials such as fly ash, slag, and mining tailings, reducing the demand for natural resources and providing a solution for waste disposal. By combining this newfound material with the already eco-friendly properties of 3DCP, Hive3D Builders has unlocked tremendous potential for reducing carbon emissions in the building process. The current estimate is a reduction of 93% of the construction’s CO2 emissions. With this tremendous cut in greenhouse emissions, Hive3D Builders is at the forefront of sustainable construction technology.

Superior Strength
The implications of this innovation extend beyond its environmental benefits. Along with its reduction in CO2 emissions, the carbon-neutral material also offers superior strength and durability. This increased adhesion makes it an attractive alternative to traditional cement, offering immense potential for building more resilient structures. The strength of the material can be accredited to the geopolymer’s desirable properties. It is no wonder that geopolymers, oftentimes used as construction materials, were a key component in Hive3D Builders’ material. They exhibit advantages like excellent strength, high durability, and outstanding fire resistance.

Material Costs
3D concrete printing material generally has a significantly higher cost than regular concrete. This is because 3DCP does not use regular cement, but a mortar that dries notably quicker than regular concrete does. CyBe Mortar, for example, sets in three minutes and achieves structural strength in only one hour. This fast drying speed is needed because the bottom layers need to be strong enough to print the rest of the structure on. This special, fast-drying mortar, however, often comes at a higher cost than regular concrete does. Still, 3DCP is generally cheaper than regular construction. The technique has unique cost-saving properties due to a lower material need, as well as less necessary construction workers. 

Hive3D Builders’ newly developed material, however, enjoys yet another advantage in this regard. Hive3D developed a unique system to automatically mix the cement replacement onsite with hyper-locally sourced aggregates to lower their material costs exponentially. By creating this system to automatically mix the cement replacement product onsite with locally sourced aggregates, the company is able to lower the cost of its printing mortar to a third of the price of other commercially available printing mortars. This low cost might pave the way for many hesitant construction companies to finally make the switch to 3DCP. The development of this new low-cost, carbon-neutral material is poised to shape the additive manufacturing industry.

Revolutionizing the Construction Industry
One of the main reasons that 3D concrete printing is not as common as you would expect it to be after hearing the advantages, is the fact that construction companies are often hesitant to change their way of working. The construction industry is booming, so big companies in the industry often don’t have the time or need to properly consider new building technologies like 3DCP. When they hear about the technique’s higher material price, they often lose interest, without taking into account the cost savings on other aspects. With Hive3D Builders adding a low material price to the material’s already impressive list of better sustainability and superior strength, the sustainable innovators might be able to convince headstrong construction giants to consider additive manufacturing as a cheaper, faster, and more sustainable alternative to their current construction methods. Using their partner CyBe Construction’s printer and Hive3D Builders’ carbon-neutral material, the company is set out to revolutionize the construction industry on a global scale.
