Microlight3D, a specialty manufacturer of high-resolution micro-scale 2D & 3D printing systems for industrial and scientific applications, today announcestheaward of FET-Open European funding to develop microstructured concrete that will transform a buildings capacity to cool down, naturally.

This nanotechnology project, led by MIRACLE-a European consortium of five universities and Microlight3D, has the potential torevolutionize the construction industryand considerably lower the impact concrete buildingshave on the environment.


“By using microstructured concrete, buildings will be able to cool down naturally and thereby reduce the “urban heat islands” that build upin cities during summer heatwaves, which can make these spaces unbearable,” said Denis Barbier, co-founder & CEO of Microlight3D. “This structural building material, which can cool down by itself, will also reduce the energy consumption used for air conditioning and benefit the climate by lowering CO2 emissions.”


The consortium selected Microlight3D for the ability of its 3D microprinting technology to create 3D microstructures at ultra-high resolution, in materials rigid enough that they can be used as molds for concrete and create microtopographies.


In this project, Microlight3D will use its two-photon polymerization technologyto create microstructures which will be used as molds for concrete. This will allow steel microfibers to be inserted inside the microtopography variations created at the surface. In doing so, the concrete will be transformed into a photonic metamaterial, converting the solar heat into infrared wavelengths that are then reemitted through the atmosphere. The photonic meta-concrete is thereby able to expel heat from buildings into outer spacewithout consuming any extra energy.“


Microlight3D is proud to participate in a project aimed at creating cities that are more pleasant to live in and more respectful of the environment,” said Philippe Paliard, co-founder and head of users & applications atMicrolight3D. “It is exciting to see that our two-photon polymerization technology can offer solutions to, and have a real impact on, combatting environmental issues.”


The project will run four years. Led by the Spanish Superior Council for Scientific Research (CSIC – Madrid), members of the MIRACLE consortium (Photonic Metaconcrete with Infrared RAdiative Cooling capacity for Large Energy Savings) include:

  • Technische Universitat Darmstadt (Germany)
  • Universidad Publica de Navarra (Pamplona, Spain)
  • Fundacion TecnaliaResearch & Innovation (San Sebastian, Spain).
  • Katholieke Universiteit Leuven (Belgium)
  • Politecnico di Torino (Italy)
  • Microlight3D (Grenoble, France)
