Researchers at Rice University have made a groundbreaking discovery, unlocking the potential to use 3D printing to create sustainable wood structures. This innovative approach offers a greener alternative to traditional manufacturing methods, which have historically been marred by wasteful practices.
The research team, led by Muhammad Rahman, Assistant Research Professor of Materials Science and Nanoengineering at Rice University, has developed an additive-free, water-based ink made from lignin and cellulose, the fundamental building blocks of wood. This ink can be used to produce architecturally intricate wood structures via a 3D printing technique known as direct ink writing.
“The ability to create a wood structure directly from its own natural components sets the stage for a more eco-friendly and innovative future,” said Muhammad Rahman, Assistant Research Professor of Materials Science and Nanoengineering at Rice University. “It heralds a new era of sustainable 3D-printed wood construction.”
The implications of this discovery are far-reaching, potentially revolutionizing industries such as furniture and construction. According to Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor in Engineering and Professor and Chair of Materials Science and Nanoengineering at Rice University, “Unlike previous attempts, this method exclusively uses nanoscale wood components for 3D printing, marking a significant advancement in the field.”
The research was supported by Rice University and the United States Department of Energy’s Office of Science, Basic Energy Sciences and Engineering Division.
