There is a brand new company with 30 million in funding from silicon valley investors on the scene of Automated Construction that just came out of stealth mode in August 2020 and they’ve already delivered their first 2 units to customers.
Anyone who has done construction in California is familiar with the shortage of skilled laborers that is driving construction costs through the roof stick built housing in California costs $321. Mighty buildings has developed a solution decreasing this cost by 45%. Of course if the land has precarious circumstances the cost to build a secure foundation could be well over the expense for the home.
Mighty Buildings has been developing a solution for 3D printing unlike any I’ve seen on a large scale. With a custom printer and custom material, Mighty Buildings has differentiated their product significantly from materials based on Portland cement.
They call it synthetic stone. This material is lighter and supposedly stronger than concrete while also having an even higher thermal resistance which is an enormous benefit in the fiery land of California. Having a home that is fire resistant to this degree can be the difference between having a place to go back to after a natural disaster. Unlike concrete which cures over time, Mighty Buildings synthetic stone requires ultraviolet light to instantly harden which creates such a strong structure that they can 3D print a flat horizontal roof with a breadth up to 14ft.
All of their printing is done completely off site in one of their controlled facilities. After it is printed they use a crane to drop it into place. If it is a bigger home then it will be placed one section at a time but the smallest model is all in one. Down the line, they are looking towards solutions that will chemically seal the modular segments together so that the exterior shell can form a monolithic impenetrable structure. Achieving a monolithic structure offers many benefits like preventing water damage, and improving insulation which in turn can decrease your electric bill and improve the overall sustainability of your home.
Mighty buildings first home has already achieved a Certificate of Occupancy for their first residential homes and the occupant seems quite satisfied so far. This was made possible largely because they got the material they are using to be UL certified which goes a long way in cementing the legitimacy and trust in their product.
Mighty buildings is much more a tech startup than a construction company and that is evident in their approach to the entire process. It will be very exciting to see this company grow as they reach their early adopter customer base and begin to receive feedback on a large scale on what it is actually like to live in one of these homes. As with any tech I am positive that Mighty Buildings will be constantly trying to improve their product.
3D printing lends itself to intricacy because if you can make a really cool model or a unique parametric design then a 3D printer can achieve a level of detail that would be absolutely cost prohibitive otherwise. Designing models like that can take a long time but once they are made they can be printed over and over with the press of a button. Because of this there is no doubt that the Mighty Buildings catalog will be expanding drastically over time.
If they had no interest in offering a diverse lineup of products then they would have just build injection molds for their current product line but instead they opted for the infinitely more versatile option of 3D printing.
In the near future I have some really awesome videos planned with some really awesome companies, I am really looking forward to stepping up my game as I continue to research automated construction sharing my findings.
