Stone Printing

Desamanera implements the Dinis’ enormous 6m x 6m x 6m 3D printer capable of producing large objects, whether they be architectural components, art pieces, or serial parts. As pioneers in the field of large-scale 3D printing, the Dinis are not only important for proving that such technology is possible, but also for demonstrating that it can be done with local, sustainable materials. Desamanera promises the same capability, advertising its ability to 3D print in stone from granulated rock, relying on non-polluting natural binders to fuse pieces together.

Empty areas, undercuts, curves, corners and cantilevered items; it is even possible to develop parts inside the object.” Additionally, the process is suggested by Desmanera to be four times faster than carving stone, with prints taking only 8 to 10 hours to complete at 10 cm per hour. Though the company’s gantry-style printer might be hyped for printing buildings, the Italian startup sells its ability to construct art pieces as well as other architectural components to be added to already completed structures.

It should be noted that Desmanera doesn’t only 3D print giant, stone pieces, but applies post-processing finishes to add unique characteristics to the prints. With a technique called MarmoLiquido™, stone works are coated with a marble finish, from a large range of choices, in order to provide the look of marble, without the same cost. Other finishes that can be applied include water and mold resistant and, even, luminescent materials.

The path of Enrico Dini has been a tumultuous one, but the Civil Engineer and his brother have ultimately developed a technology that could completely change the field of construction for good. In the process, they’ve managed to 3D print numerous stone sculptures, a small house, and test prints for potential 3D printing on the moon. We’re still waiting for the Dinis to 3D print some of the large buildings they’ve been contracted to create, but, when they do, I’m sure they’ll be amazing.
