Maintenance Considerations

While 3D-printed homes offer numerous benefits like affordability, sustainability, and speed of construction, it’s essential to be aware of potential maintenance needs—especially for systems that go beyond the printed structure itself.

Electrical Systems: Since 3D printers currently focus on building the walls and core structure, traditional methods are still needed for installing wiring and electrical systems. Ensuring that your home has a solid plan for safe, efficient electrical integration is crucial, just like in any other home.
Plumbing: Plumbing is another key system that will need conventional installation methods in 3D-printed homes. Planning for proper piping, drainage, and potential future repairs should be a priority. Consider discussing with your builder how these systems are incorporated to ensure they meet local building codes and long-term functionality.
HVAC: Heating, ventilation, and air conditioning systems (HVAC) in 3D-printed homes are installed similarly to traditional homes. Since 3D printing allows for customized design, it’s important to work with a professional to ensure the HVAC system is well-suited for your home’s unique layout, insulation, and airflow needs.

Overall, while the 3D printing process streamlines construction, key infrastructure like electrical, plumbing, and HVAC systems still require thoughtful planning and expert installation to ensure a fully functional, maintainable home.

Correcting an infrastructure issue in a 3D-printed home is similar to addressing the issue in a traditionally built home, but there are a few unique considerations due to the nature of 3D-printed walls and structures.

ACCESS: In 3D-printed homes, infrastructure is usually installed inside channels that are either pre-planned during the design phase or carved into the printed walls after construction. To correct a problem:

Locate the issue: Infrastructure systems should have accessible shut-off valves/panels and issue detection may require cutting into the walls to find the affected area.
Cutting into the walls: While concrete or composite materials are used for printing, specialized tools (like a concrete saw or drill) may be needed to cut into the walls to reach the issue.

REPAIR: Once the issue is exposed, the process of repairing or replacing them is similar to traditional homes:

Patch or replace: Depending on the severity of the issue, a patch may be applied, or the damaged section may need replacement.
Re-installation: After the fix, any fittings or insulation will need to be restored to ensure the issue remains secure and efficient.

WALL REPAIR: Once the repair is completed, the wall itself will need to be patched:

Fill the opening: The opening in the 3D-printed structure is typically filled with a compatible material, such as concrete or plaster, to restore the wall’s integrity.
Repainting or refinishing: After the patching material dries, it will need to be sanded and repainted to match the rest of the structure.

Challenges and Solutions

Wall material: Since 3D-printed walls are often made of concrete or other durable materials, accessing infrastructure can be more labor-intensive compared to drywall. Using scanning technology or referring to the original 3D design plans can help reduce the amount of cutting required.
Design for maintenance: Builders of 3D-printed homes may incorporate design features that allow for easier access to systems, such as built-in service panels or modular components.

Overall, while the materials used in 3D-printed homes add some complexity to accessing systems, the repair process is quite similar to traditional construction once the infrastructure is exposed.

Where is the Market Headed?

Mass Adoption in Developing Markets: Countries with significant housing shortages or high demand for affordable housing will likely be early adopters. 3D printing could help resolve these issues quickly and at scale. Regions like Latin America, Africa, and parts of Asia could become hot spots for 3D-printed homes in the next decade.
Innovations in Materials: Expect advancements in the types of materials used for 3D home printing. New composites, eco-friendly materials, and even materials sourced from local environments (like sand or dirt) will expand the possibilities for what types of homes can be printed and where they can be built.
Mainstream Adoption in 5–10 Years: While still in the early stages, 3D home printing could become mainstream by 2030. As the technology matures and regulatory hurdles are addressed, we’ll see more developers and builders adopting it for both affordable housing and custom-built homes. By 2030, it is anticipated that 3D-printed homes could constitute a noticeable portion of the global housing market.
Commercial and Industrial Applications: Beyond residential homes, we will likely see 3D printing adopted for commercial and industrial construction. Warehouses, office spaces, and even retail buildings could be printed with similar benefits of speed, cost efficiency, and customization. Walmart has already given it a test drive with one of their newer warehouses as the largest commercial endeavor to date.
