Quick answer: A 3D printed home starts with a digital design and engineered plans. A large printer extrudes a special concrete mix layer by layer to form the walls, with reinforcement and openings planned in. Miniopolis prints wall panels off-site, indoors, while the foundation is built, then sets the panels on site. The roof, windows, plumbing, electrical and finishes are completed much like a conventional home.

Step by Step
- Lot review: zoning, flood zone, utilities and access. Building on your own lot? Send us the address.
- Design: choose a model or custom plan. Curves and rounded corners cost little extra to print.
- Engineering: a Florida-licensed engineer designs the walls, reinforcement and connections for the site’s wind and flood requirements.
- Permit: we submit plans to your city or county building department.
- Site work and foundation: clearing, fill if needed, utilities and the slab or elevated foundation.
- Printing: wall panels are printed indoors at the same time, so weather does not delay printing.
- Panel setting: panels are shipped, set and connected on the foundation.
- Roof and openings: roof system, impact windows and doors.
- Mechanical, electrical and plumbing rough-in and inspections.
- Finishes and final inspection: interior finishes, certificate of occupancy and move-in.
Why Print Off-Site
Printing indoors gives consistent conditions for the concrete, around-the-clock printing and quality control before panels reach your lot. It also overlaps printing with site work, which shortens the overall schedule.
What Takes the Longest
Printing the walls is fast. Permits, site work, the roof and finishes take most of the calendar, just as in any new home. See also permits for 3D printed homes.
Frequently Asked Questions
How long does it take to 3D print a house?
Printing the walls takes days, not months. Permits, site work, the roof and finishes take most of the total schedule.
What is a 3D printed house made of?
The walls are a specialized printable concrete mix with reinforcement. The roof, windows and interior are built with conventional materials.
Are 3D printed walls printed on site?
Some builders print on site. Miniopolis prints wall panels off-site indoors and sets them on the foundation.
