Lafarge to deliver the first 3D concrete houses to Zimbabwe
Lafarge Cement Zimbabwe is about to deliver the first 3D concrete houses to Zimbabwe. According to the company, to showcase the capabilities of 3D printing, Lafarge Cement Zimbabwe will build 10 units in Knockmalloch as part of the affordable housing project currently underway.
“These 3D concrete houses in Zimbabwe will allow relevant stakeholders to witness and experience the capabilities of this innovative technology and it is expected that this will attract more projects towards using the technology to provide decent housing and affordable, ”the company said.

This technology was developed by LafargeHolcim through its subsidiary 14 Trees and the new dry mortar mixing plant will produce the 3D printing ink required for local projects. 3D printing technology uses computer aided design (CAD) to create three-dimensional objects through a method of layering. It’s simply a matter of layering materials, like plastics, composites, or biomaterials to create objects that vary in shape, size, stiffness, and color.
The process consists of a printer with a robot with a mechanical arm that can move on a track in different directions to lay mortar in a pattern on a print bed as designed on a computer. The dry mortar in a silo is mixed with water in a mixer and pumped through a hose to a nozzle mounted on the end of the robot arm.
A 3D printed house can be completed in just 12 hours, compared to four days with normal construction methods. The company says the technology can reduce its carbon footprint by up to 70%, helping Zimbabwe and other African countries on the climate change project.
