As is known to all, the world famous Notre Dame is very unfortunately caught on fire on the evening of April 15, 2019, and its iconic spire collapsed under the flame. Hundreds of firefighters rushed to the scene to rescue, eventually successfully controlling the fire and protecting the main structure of Notre Dame.
French President Emmanuel Macron promised to rebuild Notre Dame in just five years. It is difficult to achieve this time frame using traditional construction methods, but one company believes that 3D printing technology can be used.
The Dutch design firm Concr3de said it can be recovered not only and can be completed within the five-year target. It can retain the original design and its cost may be lower than the repair fund. They can even use the charred remains of the cathedral during the restoration process.

Concr3de co-founder Eric Geboers said in an interview with France 24: “As the level of damage becomes more apparent, it is time to consider how to reconstruct this historic sacred monument. We propose a modern reconstruction The strategy of Notre Dame de Paris, the strategy maintains the soul and layered history of the building.
“Why don’t you reuse the rest? What if we take away the remains of Notre-Dame and re-establish them with them? If we take those long-established stones and use them to preserve the soul of the building?”
Reconstruction with residue.
Concr3de recommends combining old materials with new technologies. They will collect ashes, dust and damaged stone residues in the nave of the cathedral and turn them into 3D printable powder. “This powder will have a yellow-gray color of Parisian stone and will be mixed with the charred wood mixture. We can use this powder to directly print the damaged part of Notre-Dame in 3D.
“The remaining ash and limestone may account for about half of the material needed. Then we tie them together. But we won’t use any plastic or resin. It will be a more natural and purer procedure than this.”
“It’s impossible to say exactly how long the job will take at this stage, but it will definitely be completed in five years,” Geboers said. “Using our technology is at least five times faster than cutting stones.
