Mighty Buildings raises $100m for carbon-neutral 3D-printed homes

Construction technology company Mighty Buildings has raised a total of $100 million (£72m) to date to make carbon-neutral 3D-printed homes a viable option.

The firm has committed to net zero emissions by 2028 – 22 years ahead of the construction sector.

Mighty Buildings said its homes are currently developed with sustainability in mind - from a 3D printing construction process that eliminates 95% of construction waste to the zero net energy finished product.

Onsite renewables and climate control technologies are used which further reduce the impact of its homes.

The company's long term vision is to use a combination of 3D printing, robotics and advanced composite materials with the latest in design to create a network of “micro mighty factories”.

Such facilities would be capable of producing 200 – 300 homes per year in locations where housing gaps exist, creating sustainable housing options quickly, locally and at scale.

Sam Ruben, Co-Founder and Chief Sustainability Officer said: “While we have already made significant progress towards our 2028 carbon-neutrality goal with the next generation of our proprietary Light Stone Material (currently undergoing certification), this funding will allow us to accelerate our research into bringing the next phase of our roadmap to life and hopefully stepping beyond neutrality into true regeneration/circularity.”

The latest round of funding, which raised $22 million (£16m), was supported by new and existing investors including ArcTern Ventures, Core Innovation Capital, Decacorn Capital, Gaingels, Khosla Ventures and Vibrato Capital.

Mira Inbar, Partner at ArcTern Ventures added: “ArcTern Ventures invests in sustainable technology with the potential to create enormous social and environmental benefits.

“We're enthusiastic about how 3D printing technology and robotics automation can be implemented to create modern, high-quality and sustainable net zero energy homes."
