Researchers at the University of Sydney are putting together the technology of 3D printing and the power of macadamia nut shells in a research project that may change the face of the Australian construction industry altogether. In using the shells as a source of 3D printing material that they have been able to use to create a sustainable timber prototype, the researchers see the potential for using the 3D printed material in walls, louvres, and cladding. Would you ever have imagined using macadamia nut shells to 3D print timber? Let's hear your thought!
