Instead of just relying on <a href=\"https:\/\/facfox.com\/news\/topics\/mechanics\" target=\"_blank\">mechanic<\/a>al ventilation systems, the team has created a hygroscopic 3D printed material that can store moisture and later release it. The material in question is based on a geopolymer derived from marble quarry waste.<\/p>\n<p>The idea driving the researchers is to establish more passive dehumidification solutions that, unlike <a href=\"https:\/\/facfox.com\/news\/topics\/mechanics\" target=\"_blank\">mechanic<\/a>al ventilation systems, do not increase <a href=\"https:\/\/facfox.com\/news\/topics\/energy\" target=\"_blank\">energy<\/a> costs and consumption. The solution they propose is a geopolymer material 3D printed into structures that can be installed in ceilings and walls, where they temporarily absorb moisture from the air, and then release the moisture when the room is ventilated. In other words, the 3D printed geopolymer could be a good candidate for buildings that already have a ventilation system and are looking to reduce their reliance on it.<\/p>\n<p>As Guillaume Habert, Professor for Sustainable Construction and supervisor of the research project, specifies: \u201cOur solution is suitable for high-traffic spaces for which the ventilation systems already in place are insufficient.\u201d<\/p>\n<p>With sustainability being a priority, the researchers looked to byproducts and waste materials for their solution. In the end, they chose to work with waste from marble quarries, which has hygroscopic properties. In order to turn the marble production byproduct into a printable material, the team both ground it down into a fine powder and combined it with an alkaline solution, which acts as a binder for the geopolymer material. The resulting material bears similar properties to cement but is far less <a href=\"https:\/\/facfox.com\/news\/topics\/energy\" target=\"_blank\">energy<\/a> intensive to produce.<\/p>\n<div style=\"background-color: #eaeaea7a;padding: 15px 30px;align-items: center;border-radius: 4px;box-shadow: -1px 4px 20px 0px #dedede;margin-top: 1em;margin-bottom: 1em\">\n<div style=\"flex: 1;padding-right: 30px\">\n<h4 style=\"margin-bottom: 14px\">Manufacturing on Demand<\/h4>\n<div>3D Printing with over 100 materials, shipping globally with competitive low cost, get quotes for your projects now!<\/div>\n<\/div>\n<p><a href=\"https:\/\/facfox.com\" target=\"_self\" rel=\"noopener noreferrer\" style=\"background-color: #0baee8;color: white;padding: 10px 20px;border-radius: 4px\"><i aria-hidden=\"true\" class=\"fa-fw auxicon auxicon-cloud-upload\"><\/i> Get Quote<\/a><\/div>\n<p><img decoding=\"async\" src=\"\/wp-content\/uploads\/2025\/01\/7642878693037732925.jpg\" class=\"aligncenter\">   Screenshot   <\/p>\n<p>At this stage in the research project, the ETH Zurich team has successfully 3D printed a small prototype, measuring 20 x 20 x 4 cm using a binder jet technology. The <a href=\"https:\/\/facfox.com\/service\/3d-printing-service\" target=\"_blank\">3D printing<\/a> process, carried out by a group led by Benjamin Dillenburger, Professor for Digital Building Technologies, leveraged a mobile jet print head to selectively deposit a potassium silicate binder onto layers of the geopolymer powder. In fact, the binder jetting system used in the project was actually developed by one of the project\u2019s supervisors, architect Pietro Ogaglia. Notably, this isn\u2019t the first time that ETH Zurich researchers have experimented with 3D printed marble-based geopolymers: in 2023 we covered a story about how rock flour was used to 3D print a series of stunning architectural floor elements.<\/p>\n<p>To test the effectiveness of the 3D printed material, the ETH Zurich team conducted a simulation that was based on a library reading room used by 15 people. In this simulation, the researchers wanted to evaluate the impacts of completely lining the ceiling and walls with the 3D printed components to determine the discomfort index, which indicates the \u201closs of comfort\u201d caused by high or low humidity. The simulation ultimately found that with components 4 cm thick, the discomfort index could be reduced by 75% compared to normal walls, while a 5cm-thick covering could decrease it as much as 85%.<\/p>\n<p>\u201cWe were able to demonstrate with numerical simulations that the building components can significantly reduce humidity in heavily used indoor spaces,\u201d summed up Magda Posani, a building physicist who led the study on the geopolymer\u2019s moisture-absorbing properties.<\/p>\n<p>Since the wall components dehumidify passively, they can also have a positive impact on the climate, reducing <a href=\"https:\/\/facfox.com\/news\/topics\/energy\" target=\"_blank\">energy<\/a> consumption and emissions associated with <a href=\"https:\/\/facfox.com\/news\/topics\/mechanics\" target=\"_blank\">mechanic<\/a>al ventilation systems\u2014an appealing characteristic, p<a href=\"https:\/\/facfox.com\/news\/topics\/art\" target=\"_blank\">art<\/a>icularly for buildings and organizations looking to achieve net zero targets. The next steps for the promising research initiative will be to further develop the dehumidifying solution and scale it for industrial production.<\/p>\n<div>\n<div><\/div>\n<\/div>\n<blockquote style=\"font-size: 16px;border-left: 4px solid #cdcdcd;border-radius: 4px;background-color: #f9f9f9;font-weight: 500;color: dimgrey\">\n<h5 style=\"margin-bottom: 6px\">You might also like:<\/h5>\n<p><a href=\"https:\/\/www.voxelmatters.com\/researchers-patent-bendable-concrete-for-3d-printing\/\" target=\"_blank\">Researchers patent bendable concrete for 3D printing: <\/a>Traditional construction relies on people operating heavy machinery to place steel or wood beams to create a building frame, but the process can be dangerous and expensive.
