New research is showing positive results when harnessing 3D printing technology to combine timber and plastic waste and create high-performance building elements.
Waste is a pressing global problem that depletes our primary resources and聽impacts on our environment. The construction industry is a prime offender,聽consuming 30-50% of primary materials and producing around 40% of landfill聽through construction and demolition. In Australia, 85% percent of logged聽timber and 88% of plastics are wasted and end up in landfill. This project shows聽that timber and plastic waste are a valuable resource and can be transformed聽into smart sustainable building elements, using advanced manufacturing聽technologies in the form of 3D printing.
3D printing can do things that current construction technologies cannot: The聽3D printing process allows architects to design at the nanoscale, fluidly varying聽the material composition and printing parameters to make building elements聽of variable strength, density, shape, texture and colour as demonstrated in the聽microtimber prototypes. Future research will develop this concept towards聽building houses that are affordable and sustainable and can be recycled.
