Unveiling the Future of Sustainable Construction: 3D Printing with Plants

Remember the Chia Pets that used to adorn our shelves and windowsills? Well, the University of Virginia (UVA) is taking that concept to a whole new level. Researchers at UVA are pioneering the use of 3D printing combined with “soil ink” to create architectural structures that integrate plants and greenery within their very structure, rather than simply being added as an afterthought. This groundbreaking technology could pave the way for carbon-neutral or even carbon-negative building solutions.

Traditional construction materials have a large carbon footprint, contributing significantly to environmental degradation. However, by replacing these materials with circular alternatives that can be recycled and reused, we can significantly reduce their ecological impact. Through the use of “soil ink” and cutting-edge architectural designs, UVA researchers are harnessing the power of 3D printing to achieve this revolutionary goal.

Of course, like any pioneering endeavor, they encountered their fair share of challenges along the way. As structures grew taller and heavier, the researchers faced soil cracking issues. They also had to find innovative ways to insulate the inner walls from the outer layers of soil, employing a mix of different materials to address this challenge.

This project builds upon previous work exploring the intersection of 3D printing and plants, such as using mycelium and plant appliances. The 3D Printing Studio at UVA is open to all students interested in exploring this fascinating field. To gain access, students must complete an online orientation and undergo an in-person assessment. UVA also provides advanced training for certified users and has a knowledgeable staff on hand to assist those less familiar with the technology.

The UVA School of Architecture boasts a state-of-the-art Fabrication Lab, affectionately known as FabLab, which serves as a hub for empowering people with tools for making, prototyping, and construction across various scales, materials, and techniques. Managed by Melissa Goldman and Trevor Kemp, two experienced fabrication experts, and a team of undergraduate and graduate student assistants, the FabLab offers a vast array of resources, including metal and clay 3D printers, as well as Kuka robots. This impressive facility is dedicated to both creating and teaching.

The potential of 3D printing extends far beyond academic pursuits. In fact, businesses working on developing new or improved products, processes, and software can benefit from the now permanent Research and Development (R&D) Tax Credit. By utilizing 3D printing technology, companies can elevate their R&D Tax Credits by including wages for technical employees involved in creating, testing, and revising 3D printed prototypes. Additionally, when used to enhance existing processes, the time spent integrating 3D printing hardware and software can also be accounted for. Finally, the costs of filaments consumed during the development process can be recovered when 3D printing is employed for modeling and preproduction.

With so much exciting 3D printing development happening at the University of Virginia, it’s essential for the industry to take notice and support these innovative endeavors. By embracing this technology and its potential for sustainable construction, we can shape a brighter, greener future.
