Iroko – Mobile 3D Construction Printer with Low‑Carbon Ink is a groundbreaking solution developed by 14Trees to address the pressing need for fast and sustainable building practices. This portable 3D construction printer is designed to revolutionize the construction industry by offering a more efficient and eco-friendly alternative to traditional building methods.

The key innovation of Iroko lies in its use of Holcim’s TectorPrint—a low-carbon, cement-based ink that significantly reduces the embodied carbon in construction. With up to 70% less carbon emissions compared to traditional concrete, this ink enables the rapid construction of one- and two-story structures with minimal environmental impact.

One of the standout features of Iroko is its portability and ease of assembly. The printer is lightweight and container-transportable, allowing for quick deployment in both urban and remote locations. By eliminating the need for cranes during assembly, Iroko streamlines the construction process and enables the printing of homes, schools, clinics, and other public infrastructure in a matter of days.

Furthermore, Iroko supports digital design flexibility, reducing waste through precision printing and ensuring that each structure meets the desired specifications with minimal material wastage. The system has already been successfully used to build the world’s first 3D-printed school in Malawi and the largest EDGE-certified housing community in Kenya, showcasing its versatility and effectiveness in real-world applications.

This innovative solution is particularly well-suited for NGOs, governments, and developers looking for fast, low-carbon building solutions that can be easily scaled to meet the growing demand for sustainable infrastructure. As part of 14Trees’ turnkey model, the Iroko solution includes technical design, engineering support, onsite training, and local material sourcing, creating opportunities for job creation and fostering scalable social impact in communities around the world.
