A California startup called 4DIFY has completed the first fully 3D-printed home in a small experimental neighborhood in Yuba County, north of Sacramento. The home was built using industrial-scale 3D printers that layer concrete inch by inch, forming the walls of the structure with automated precision. The project is part of a cluster of five 3D-printed homes being built in the area, with the first home already listed for sale at $375,000.

Why it matters

The 3D-printed home technology used by 4DIFY has the potential to dramatically reduce construction timelines, labor costs, and material waste, making housing more affordable in a state grappling with housing shortages. The homes are also designed to be more durable and resistant to fire, mold, and pests, which could lead to lower insurance costs for homeowners.

The details

Instead of traditional wood framing and teams of construction workers, the 3D-printed home was built using industrial-scale 3D printers that layer concrete inch by inch, forming the walls of the structure with automated precision. The roughly 1,000-square-foot home took just 24 days to print, and the team expects future builds to take as little as 10 days. The homes are designed to be fire-resistant, mold-resistant, and pest-resistant, which may lead to lower insurance costs for homeowners.

  • The first 3D-printed home was completed in February 2026.
  • The 3D-printed home took just 24 days to print.
  • The team expects future builds to take as little as 10 days.
