3DCP™ – Reinventing How Homes Are Built
3DCP™ (3D Concrete Printing) is a groundbreaking construction technology that PCI Builders is bringing to California. PCI’s first 3DCP permit was approved in February 2026 for a home in Altadena, California, a community impacted by the Eaton Fire in early 2025.
As communities rebuild after devastating wildfires, technologies like 3DCP™ offer a new approach to constructing stronger and more resilient homes.
Using a large computer-controlled system, structural walls are printed layer by layer from a digital design using a proprietary concrete mix. This advanced process allows homes to be built with remarkable speed and precision while creating strong, durable concrete structures.
For example, the walls of a typical 1,500-square-foot home can be printed in approximately 12 hours, with plumbing and electrical infrastructure installed as the walls are formed. After the concrete cures, typically 7 to 10 days, roof construction begins and the remainder of the home is completed using conventional building methods.
Incorporating fire-resistant components such as steel roof trusses and fire-rated roofing shingles results in a virtually indestructible structure built for exceptional durability and resilience.

Why 3DCP™ Makes Sense for Southern California
Southern California faces growing challenges including housing shortages, rising construction costs, and increasing wildfire risk. New technologies like 3DCP™ provide an innovative approach to addressing these issues.
Concrete structures provide exceptional durability, while the efficiency of the printing process helps accelerate construction timelines and reduce labor requirements. This combination allows builders to deliver high-quality homes more efficiently while helping address the region’s urgent need for new housing.
By bringing 3DCP™ technology to California, PCI Builders is helping lead the next generation of residential construction by combining advanced technology, durable materials, and thoughtful design to create homes built for the future.
FAQ
What is 3DCP™ (3D concrete printing)?
3D concrete printing is a construction method that uses computer-guided equipment to print a proprietary concrete mix in layers, forming the structural walls of a building directly from a digital design.
What is the process of printing a 3DCP™ home?
During the printing process, the construction area is enclosed within a temporary structure to help control environmental conditions and ensure consistent curing.
Guided by a digital design, the printer constructs both interior and exterior structural walls layer by layer. The walls of a typical 1,500-square-foot home can be printed in approximately 12 hours, with plumbing and electrical infrastructure installed during the printing process.
After curing for approximately 7–10 days, roof construction begins and the remainder of the home is completed.
Are 3DCP™ homes fire resistant?
Yes. 3DCP™ homes are constructed using concrete, which is a non-combustible building material that provides a significantly higher level of fire resistance compared to traditional wood-framed construction.
When combined with fire-resistant roofing, windows, and other building materials, 3DCP™ homes offer exceptional protection against fire.
Do 3D printed homes look different from traditional homes?
Not necessarily. The 3DCP™ printing process allows walls to be troweled and finished to resemble traditional stucco or other architectural finishes, creating a familiar appearance.
At the same time, the technology also allows for greater design flexibility, including curves and architectural shapes that would be difficult or expensive to achieve using conventional building methods.
Is 3DCP™ more affordable than traditional construction?
In many cases, yes. The efficiency of the printing process can reduce labor requirements and construction timelines, which can help lower overall building costs.
Why is 3DCP™ different from other 3D concrete printing technologies?
Many concrete printing systems leave structural layers exposed, resulting in heavily textured walls and rounded corners that make the technology obvious.
3DCP™ walls can be professionally troweled to resemble traditional stucco finishes, and the printing process produces cleaner geometry with corners that come much closer to true 90° angles.
The result is a home that delivers the strength and efficiency of concrete printing while maintaining the architectural quality homeowners expect from traditional construction.
