This is how a 3D concrete printer works

Thanks to Progreso's technological leadership, building with a 3D concrete printer is now a reality in Guatemala. The projects are printed from computerized files using a special concrete that allows the placement of overlapping horizontal layers, building the objects progressively guaranteeing construction quality adherence and integrity, as well as avoiding collapse or deformation.

This type of printer, called «Gantry», is one of several types that exist worldwide. It is the first of its kind and brand operating in Latin America. It builds objects ranging from small to large scale, although the size of the projects is not its only virtue. In addition, it has the capacity and potential to build special geometries that are not achieved with conventional concrete placement using formwork.

Another valuable feature is its contribution to sustainable construction, because it allows for more safety, generating less noise and less waste. Its efficiency is also remarkable, requiring three to four people to place 2 metric tons per hour of material, depending on printing conditions.

Taking advantage of the versatility of building with different geometries, Progreso has already built pieces of urban furniture and bus stops that have won international awards. Soon, we will be able to see the progress of a non-habitable housing prototype.

Progress is already happening. In November 2022, the walls of the pre-prototype of a non-habitable housing module were printed inside the warehouse at La Pedrera, zone 6, Guatemala City

This is not the first time that Progreso has distinguished itself as a pioneer in promoting technologies in the region. For more than 120 years, it has used cutting-edge technology in the production of cement, lime, concrete, aggregates, and other materials, as well as solutions for the construction industry.
