Revolutionizing Home Building with 3D Printing Technology
Lennar, a major home builder, has partnered with 3D printing company Icon to create the world’s largest 3D printed community, with the goal of addressing the nation’s housing affordability crisis and shortage of roughly 4 million homes. This innovative approach has already shown promising results, with 100 homes completed faster than traditional construction methods.
Benefits of 3D Printed Homes
Homeowners like Holly Feings and her husband have experienced the advantages of 3D printed homes firsthand, including energy efficiency, safety, and high-tech features. These homes are wind, fire, and mold resistant, and offer a single-level design with no stairs, making them ideal for seniors. Additionally, 3D printed model homes feature no studs, making it easy to hang pictures anywhere, and offer significantly lower electric bills, such as $26 in January, and a peaceful, quiet living environment.
Robotic Construction and Automation
A community is being built using robotic construction, with large-scale robots working continuously to produce homes at a rate of one every two weeks. This approach utilizes digital software and automation to reduce labor and increase efficiency, with features such as insulated windows and concrete reducing external noise. The goal is to automate and reduce labor costs, currently requiring a minimum of three operators, with plans to automate further and potentially have one person monitoring a dozen systems.
Partnership and Future Plans
LAR is partnering with Icon to build homes using 3D printing technology, with plans to invest in innovation and scale up production to bring down cycle times and costs. The project had a rocky start with significant delays and costs, but ultimately, Icon and LAR learned valuable lessons, including the need for thinner walls and a more open floor plan, which will save time and money in future projects. Developers are planning a new community 7 miles away with twice as many homes at a more affordable price point, utilizing a redesigned wall system for faster and more cost-effective construction.
Challenges and Opportunities
While 3D printing technology has shown promise, it is not yet as profitable as traditional methods and may face challenges in areas with stricter building laws. However, the speaker sees a significant business opportunity in using fire-resistant materials, particularly in states like Florida and California, and is interested in using LAR to build resilient homes in hurricane and wildfire prone areas. With continued innovation and investment, 3D printing technology has the potential to revolutionize the home building industry and address the nation’s housing affordability crisis.
