Contec Australia has completed the nation’s first multi-story 3D printed homes in Tapping, Western Australia. The project demonstrates a faster, cheaper, and more sustainable solution to current housing industry challenges.
A New Frontier for 3D Printing Construction Australia
The two-story residence was finished in just five months. Its structural walls were 3D printed in only 18 hours of active printing time, using a specialized concrete mix that sets in under three minutes.
This Contec Australia multi-story home is notable for printing the structural walls on both levels. The approach differs from many U.S. projects by companies like Icon that often use a hybrid model with timber or steel frames for upper stories.
Cost, Strength, and Sustainability Benefits
The 3D printed house cost vs traditional masonry shows significant savings, coming in 22% cheaper than a comparable build in the region. The home’s walls are also more than three times stronger than standard brick construction.
Beyond its strength, the structure is fire-resistant, water-resistant, termite-proof, and cyclone rated. The project represents a move toward more sustainable building methods, with 30% lower CO₂ emissions than conventional concrete.
Future of Multi-Story 3D Printed Homes
This Australian achievement could signal the next step for the industry in the United States, which has largely focused on single-story housing. The development may encourage a shift toward more complex, multi-level designs.
The breakthrough demonstrates that 3D concrete printing offers a viable path to address labor shortages and rising construction costs. This technology can provide communities with faster, cheaper, and more resilient housing options.
