3D-Printed Homes and Neighborhoods
Last Updated: Mar 10, 2025Imagine living in a leaky one-room shack with seven of your family members. Your home has no indoor plumbing, minimal privacy, little sanitation, and you have a constant worry of natural disasters like an earthquake. This living condition is Candelaria Hernández's reality, where she lives in Mexico. These issues are a reality for many more in the surrounding area. A survey of over 500 local families showed that 74% of households did not feel safe in their current housing conditions, which significantly impacts their quality of life. Fortunately for Candelaria's family and 50 others, they will soon be residents of the world's first 3D-printed neighborhood.

At 500 square feet each, the 50 homes in the neighborhood will each incorporate a living room, two bedrooms, one bathroom, and a kitchen - a notable upgrade from the typical shacks in the immediate area. The homes will be seismically sound to ensure the safety of its occupants in an area of Mexico that is at high risk of earthquakes.
This 3D-printed neighborhood is made possible through a partnership formed by three organizations. New Story, a non-profit dedicated to ending homelessness, ICON, a construction technologies company dedicated to revolutionizing homebuilding, and ÉCHALE, a non-profit partner in Mexico focused on affordable housing teamed up to work on this exciting project. And, of course, they have a 33-foot-long 3D printer to thank for the homes themselves.
How Can You Print a Home?
3D-printing has become quite popular in recent years. 3D-printing is the process of making three dimensional solid objects from a single digital file. This process is achieved through an 'additive process' by laying down successive layers of material until an object is created.
An object is built on a computer using 3D modeling software, which is then 'sliced' horizontally and sent to a 3D printer for layer by layer printing. A 3D printer can use plastic, metal, nylon, resin, and many other materials for printing. Popular items that are commonly 3D printed today include dental products, prosthetics, architectural scale models, and small-scale home design features like lamps.
More and more, discussions have transitioned towards the role of 3D-printing in the housing industry. Walls, doors, and windows can be easily 3D-printed. Whole houses are a relatively new ambition in the 3D-printing world, but there have been strides in this innovative direction. Earlier this year, the first fully-permitted 3D-printed home in the United States was completed. Many believe that 3D-printing is the future of construction.
This isn't 10% better; it's ten times better. - Jason Ballard, Co-founder at ICON
He described the benefits of 3D printing as:
- Continuous thermal envelope
- High thermal mass
- Near zero-waste
- Speed
- Significantly expanded design palette
- Improved resiliency, and
- the possibility of a quantum leap in affordability.
This industry is snowballing; Acumen Research and Consulting forecast the global 3D-printing market to reach $41 billion by 2026 - with an annual growth rate of 20% in the next six years.
The Future of Housing: 3D Printing
By 3D-printing homes, issues of homelessness can be addressed on a global scale. ICON is working in the United States to address homelessness with a community of 400-square foot homes that will be completed in early 2020 in Austin, Texas.
The potential of 3D home printing is not necessarily limited to affordable housing. We can use 3D-printing to address housing issues of sustainability and resiliency.
Verónica Contreras, the Foundation Director of ÉCHALE, says that 3D printing technology is key to reducing the labor required to make affordable housing. And, she says: "The fact that this technology is being used to help the people with the biggest social gap turns it into a humanized technology."
