Digital Building Technologies (DBT) is a team at ETH Zürich that researches additive manufacturing and computational design within the architectural realm. Through the use of various digital fabrication tools, they aim to challenge traditional methods of construction and instead adopt more efficient and sustainable strategies. Their newest innovation is the use of 3D-printed foam from recycled waste for lightweight insulated walls. The new project is called Airlements and seeks to create customized building components without the use of molds through large-scale additive manufacturing technology.
