Revolutionizing Home Construction in WA: 3D Printing Booms

Strategic Insights -

A 3D concrete printer in Perth's Peppermint Grove has completed the structural frame of a home in just one week, part of a growing push to revolutionize home construction in Western Australia. This achievement, utilizing robotic printing technology, demonstrates the potential to dramatically cut build times and costs, with the project being completed during torrential downpours that would have halted traditional bricklaying crews. Founder Mark D'Alessandro of 3D printing company Contec stated that the project, which includes printing the home's pool, fences, and garden beds, is a significant step towards a future where much of a house's structure could be poured by machine.

Key Takeaways:

  • The 3D concrete printer, used by Contec, completed the structural frame of a home in just one week, reducing build time by at least three weeks compared to traditional bricklaying methods.
  • The project was completed during torrential downpours, conditions that would have otherwise halted traditional construction crews.
  • The home's entire structure, including pool, fences, and garden beds, is being 3D printed, indicating a future where machine-poured construction is possible.
  • The Western Australian government aims to contribute 25,000 homes to the national target of 1.2 million new homes in five years, but current capacity is short, with a need to change construction methods.
  • Housing Association executive director Michael McGowan emphasized the need to look at innovative methods, such as 3D printing, modular housing, and tiny homes, to deliver homes faster.
  • Modular homes, prefabricated in factories and assembled onsite, are gaining traction for their speed and efficiency, but face hurdles in acquiring land for factory space and securing finance.
  • The Commonwealth Bank has expanded its lending criteria to better support prefabricated home builds, removing a key barrier for buyers.
  • The next challenge in 3D printing technology for housing is scaling the adoption of printing machines, as it is currently expensive to bring in machines from overseas.

Statistics:

  • 1.2 million: the national target of new homes in five years.
  • 25,000: the number of homes Western Australia aims to contribute to the national target.
  • 18,000-20,000: the current capacity of the existing workforce and supply chain to deliver homes per year.
  • 20%: the cost savings achieved by using 3D printing technology compared to traditional bricklaying methods.
