Scientists 3D Printed This Home Using Wood Waste

They mixed sawdust and other wood waste with bio-resin, then fed the mixture into an enormous 3D printer – creating a new home layer by layer. The BioHome3D is a prototype for sustainable housing, say its creators at the University of Maine. Many 3D-printed homes today only print the walls but still use concrete for the foundations and floors – which is a high-carbon, labour-intensive material. Wooden homes can also be printed off-site in a factory, cutting costs further.
