INPERSO showcases Innovative 3D Printing Technology for Building Renovation

During the latest General Assembly Meeting of the INPERSO Project, in Zaragoza, an impressive live demonstration of the project’s cutting-edge 3D printer took place. The demonstration did not go unnoticed: local media outlets, including Aragón TV, and Heraldo de Aragón, covered the event, highlighting its innovation and its impact on energy-efficiency building renovation.

The 3D printer, developed within the INPERSO project, is designed to renovate building façades by directly applying insulating and finishing materials using a robotic arm. What sets this technology apart is its ability to print vertically on existing façades, a technical challenge our team has successfully addressed. The printer can work with flexible materials, such as cement and insulation compounds, and researchers estimate that a façade could be completed in as little as two hours.

The demonstration took place in Spain, a country where this innovation is particularly relevant, as approximately half of the residential buildings (over 9 million homes) were built before 1980, and lack modern energy efficient standards. By enhancing thermal insulation through external façade refurbishment, this technology offers a scalable and low-impact solution to reduce energy consumption for both cooling and heating.

The demonstration showcased how the INPERSO project is turning renovation into a faster, more affordable, and more sustainable process. It comes with great joy that our job is being showcased in local media and is shared with the world!
