The Birth of the SM2ART Nfloor Cassette Panel
The innovative SM2ART Nfloor cassette panel represents a crucial achievement in the sustainable construction sector. Developed as part of the Sustainable Materials & Manufacturing Alliance for Renewable Technologies (SM2ART) program, this project aims to replace conventional steel-and-concrete floor assemblies with a much more eco-friendly alternative.
A Collaborative Effort
This revolution in construction materials was achieved through a collaborative effort between ORNL and the University of Maine. Leveraging their expertise in materials science, engineering, and 3D printing, these researchers created a design that not only meets but surpasses the performance standards of traditional construction materials.
From Concept to Reality
The construction of the SM2ART Nfloor cassette panel evolved from concept to prototype through rigorous experimentation. The primary challenge was to design a single-piece floor panel that could be manufactured from recyclable natural materials while maintaining the structural integrity needed for building constructions. After numerous trials and errors, the researchers successfully formulated a blend of biodegradable thermoplastic polyester bioplastic (PLA) and wood flour.
The Materials Behind the Magic
What makes this floor panel truly remarkable is its composition. The researchers combined PLA, derived from corn residue, and wood flour, a byproduct of lumber processing. This blend not only provides the necessary strength but also ensures that the panel is recyclable and eco-friendly.
The Role of PLA
PLA, or polylactic acid, is a biodegradable thermoplastic derived from renewable resources like corn starch or sugarcane. It is known for its biodegradability and is widely used in various applications, including medical implants, food packaging, and now, construction. The use of PLA in the SM2ART Nfloor cassette panel not only contributes to sustainability but also ensures that the material can be repurposed at the end of its life cycle.
Wood Flour: A Sustainable Choice
Wood flour, made from the waste of lumber processing, is another key component of the floor panel. When mixed with PLA, it creates a strong, durable material that can withstand the demands of building construction. This partnership highlights the innovative approach of repurposing waste materials to create high-performance products.

The 3D Printing Process
Creating the SM2ART Nfloor cassette panel involved a large-scale 3D printing process. Using precise geometric designs, the researchers were able to deposit the PLA/wood flour mixture layer by layer, forming a single-piece floor panel in about 30 hours.
Efficiency and Automation
One of the significant advantages of 3D printing is its efficiency and automation. The process allows for continuous and autonomous production, reducing the labor requirement by about 33% compared to traditional steel floor assembly. This time-saving aspect can lead to significant cost reductions in large-scale construction projects.
Customization and Precision
3D printing also offers a high degree of customization and precision. By incorporating cutouts for electrical conduits, plumbing lines, and HVAC ductwork directly into the design, the need for additional labor-intensive modifications is eliminated. This not only speeds up the construction process but also minimizes waste and enhances the overall quality of the finished product.
Practical Advantages and Potential Applications
The SM2ART Nfloor cassette panel has been designed with the future of construction in mind. Its practical advantages and potential applications make it a game-changer for the industry.
Strength and Sturdiness
Despite being made from natural materials, the panel boasts strength and sturdiness comparable to traditional steel floor assemblies. According to Scott Tomlinson, a structural engineer at the University of Maine’s Advanced Structures and Composites Center, this single-piece floor assembly is even stiffer and provides an improved walking experience. This could be particularly beneficial for multi-story buildings that require robust floor structures.
Environmental Impact
Sustainability is a significant driving factor behind this innovation. The use of renewable materials and the panel’s recyclability ensure that the environmental impact is minimal. Unlike traditional building materials that often end up in landfills, the SM2ART Nfloor cassette panel can be repurposed at the end of its lifecycle, fostering a more circular economy in the construction industry.
Application in Modular Construction
The potential applications of this technology are vast, particularly in modular construction. This method involves creating complete sections of a building at an offsite factory before delivering them to the construction site for final assembly. The SM2ART Nfloor cassette panel’s customizability and efficiency make it an ideal fit for modular manufacturing, offering a cost-effective and sustainable solution for urban residential structures.
