[Europe's largest "3D printing building" is expected to be completed in July covering an area of more than 600 square meters] the so-called "largest 3D printing building in Europe" is under construction in Heidelberg, Germany. The building under construction covers an area of more than 600 square meters and requires more than a dozen workers to work at the same time using traditional construction methods. The use of 3D printing technology requires only one large machine and equipment, with two people on site to monitor the progress. According to a pre-typed design program, the giant machine "squeezes" the building material out of the nozzle and, like a printer, "prints" the building structure with layers of concrete or clay. It is understood that construction of the building began on March 31 this year and is expected to be completed in July, when it will become a computer server center. The 3D printing machine equipment used in the project is provided by a Danish company that completed Europe's first 3D printing building in 2017 and has sold more than 65 construction 3D printers worldwide.
