Large-scale grid structure printed by 3D robot space
Recently, at the L'Usage des Formes exhibition in the Tokyo Palace in Paris, a unique 3D printed work called “Rainbow†earned the attention of the audience. As you can see from the picture below, it is an ultra-large hollow structure composed of a segmented line structure. This structure is the first of its kind in the world by the Gramazio Kohler Institute, which combines digital manufacturing with construction production in Zurich, using large-scale building structures made with automated robotic 3D printing.

According to China's 3D printing first interactive media platform, the Antarctic bear understands that the rainbow is 12 meters long and is assembled from 12 separate parts. Its manufacturing tool is an industrial-grade robotic arm equipped with custom extrusion tools. Each of these devices can extrude a 12mm plastic wire in less than 1 second, freeing up the 3D printing of a continuous grid structure in space. 
The material used in the rainbow is the extruded ABS polymer, which does not contain any additional assembly materials, so it can be completely recycled. Due to the fluidity of the overall design and the dense peripheral mesh layer connected by two parts, the Rainbow is undoubtedly a highly adaptable structure that can meet a variety of space requirements. Even more surprising is that it consumes very little material, a total of only 70 kg is about 8m3. 
Developers have explained that their 3D printing approach has a unique advantage over traditional methods: it can be freely manufactured in space, can be scaled, and exhibits complex geometries using a simple wire 3D printing process. Great potential for building structure development.
They also said that if combined with innovative robotics, this spatial 3D printing would be many times more time and resource efficient than the 2D material level because it can deliver the material directly to the desired location. 
Although it has not really entered the stage of building use, Rainbow is still an innovation in design and materials research that combines real architecture with digital manufacturing. It is believed that as technology continues to advance, this approach will soon be available for more practical projects, helping designers to achieve architectural design in a better way.
