A copy of Michelangelo’s statue of David created using 3D technology

Michelangelo’s Michelangelo is photographed with the flash of nearly 2 million tourist cameras each year David Today, it is a project to create the most faithful and sophisticated reproduction of the statues ever made, illuminated by high-tech scanners.

A copy of the Renaissance masterpiece, currently forged in Florence, will star at the Dubai Expo 2020, which was rescheduled in October this year.

A unique challenge involving a team of engineers, technicians and restorers is a combination of classical art and cutting-edge technology.

The· 3D David Located in the heart of Italy’s Expo Pavilion, it is praised by the world. The original is in the lonely silence of the Accademia Gallery in Florence.

It is currently closed to combat coronavirus.

Launched a few months ago, the project includes three phases. Scanning statues to create 3D digital twins, 3D Printing of various parts, and purification and assembly of those parts by repairers.

In the first phase, which took place at the end of December, the statues were scanned in centimeters. It’s not an easy task as it is over 5 meters high.

All details and nuances had to be captured on a device with a tolerance on the order of microns, which is thinner than the hair.

Equipment, usually related to the industrial sector, such as scanners used to check wind turbine prototypes, was used for the first time in the art world.

Researchers at the University of Florence collaborated with engineers from Hexagon, a Swedish multinational company specializing in precision measurement technology.

It took more than 40 hours to scan the statue using a tracer combined with a laser.

Experts then used a projector that illuminates the surface of the statue and two high-resolution cameras to capture as much detail as possible.

It’s not the first time David It has been digitized. In 1999, a group of Stanford University scholars performed a three-dimensional scan of it.

But this time, the sculpture was digitized, “I think it’s a very high level of precision, twice as high as the Stanford model made 20 years ago,” said the director of the Institute for Environmental Protection Geography. One Grazia Tucci says. Of the cultural heritage of the University of Florence coordinating the project.

Digital twins are considered to be useful for future research on statues, and can constantly monitor the preservation state of works and the behavior of surfaces, materials, and structures.

After scanning, printing started.

this time, DavidThe legs, arms, torso, and head were not skillfully carved from Karara marble for three years by Michelangelo. 3D A printer that took only a few days to make a copy from a plastic filament.

But the most delicate phase of all is the one currently underway in a small workshop in the center of Florence.

It includes a team of expert restorers, some of whom come from the Opificio delle Pietre Dure (semi-precious stone workshop), one of the world’s most important laboratories for the preservation and restoration of art. ..

The copy must go through a kind of make-up session to fully resemble the original marble, which has aesthetic and structural features that are quite different from the print version.

The restorer coats the copy with a mixture of resin and marble powder, just like painting the skin, constantly comparing the original image with the part being worked on.

“First, I cover it with stones to give it the look of Michelangelo. David, And to characterize it, render those cracks, crevices, stains, scratches, more or less smooth parts on the surface, and thus put the soul into what is actually a digital to physical matter-converted copy. Give, “says Nicola Salviori, who heads the group of restorers.

Clone David It emerges in one piece from this laboratory, lying on a special crate that is delicately transported by air to the United Arab Emirates.

None of the people involved in the project thought they were competing with Michelangelo, but as Salvioli says, they enjoy facing an unprecedented set of challenges.

“The challenge here is a pilot project, a pilot model, bringing all these materials, all these technologies together through chemistry, physics, and hard work. Our eyes and hands are constantly under pressure. Because there are, “says Salvioli.

“The difficulty is moving the statue with the static nature of the material in mind and thinking about the temperatures that this sculpture encounters, because it changes from the cold of an airplane to the heat of Dubai. “

The twins are dazzling at the Dubai Expo, but the original David Before the coronavirus pandemic, we are waiting for more than 1.5 million visitors from all over the world to visit the Accademia Gallery in Florence each year.

“He goes as a messenger. We will send him as a messenger to the Dubai Expo, which will be held in October of this year,” says Cecily Holberg, director of the Accademia Gallery.

“And he will tell you how to proceed during this time, but the original always stays here and we keep him in this museum. Visit again after these strange times we live in. I’m expecting someone. “

The Tuscan artist’s masterpiece is one of the Renaissance emblems, an overseas symbol of both Florence and Italy.

It depicts the hero of a shepherd, one of the most famous episodes in the Bible. David Armed with a simple sling, he killed Goliath, a terrifying giant who was at war with the Israelites.

Two other artists had already worked on this large block of poor quality marble, but 26-year-old Michelangelo Buonarroti succeeded where he failed.

The result was far beyond expectations, so the statue, originally intended to stand on one of the outer buttresses of the Cathedral of Santa Maria del Fiore, was placed in the center of Piazza della Signoria and was copied until 1873. Was replaced by.

Considered the ideal of masculine beauty in art, and a symbol of faith and courage to overcome brutal violence, it represents a hope for a better and safer future.

This will reach more people, the most faithful, 3D-Printed copy.
