MIT engineers have developed a sustainable alternative to traditional wood-based framing by using recycled plastic to 3D print construction-grade beams, trusses, and other structural elements for future houses. The team's 3D-printed floor truss system, made from recycled plastic, offers lighter and modular options for construction. Their goal is to provide more sustainable construction materials by utilizing recycled plastic in the building industry, as outlined in a paper published in the Solid FreeForm Fabrication Symposium Proceedings.
