Barczewko is a village of just over half a thousand inhabitants in the Warmian-Masurian Voivodeship. Its history dates back to 1325, when a watchtower for the bishops of Warmia was built here. Today, the village is distinguished by typical Warmian buildings and, more recently, an unusual, modern tank printed in 3D technology.
The investment for the Zakład Wodociągów i Kanalizacji in Barczewo was carried out by the EKO-WOD company from Kętrzyn. The printing of the tank was possible thanks to the cooperation with Holcim Polska and Globtank and the Danish company COBOD, which is famous for producing 3D printers for concrete.
By choosing 3D printing technology for the construction of the tank, 25 per cent of materials were saved and the time to complete was significantly accelerated. The method used made it possible to reduce the wall thickness and height of the tank, which is impossible to achieve with traditional construction techniques. In traditional construction, the width of the walls would be the same at the bottom, middle and top. However, structurally this is not required because the pressure of the incoming water is greatest at the bottom. 3D technology has made it possible to create a tank whose walls are thickest at the bottom and progressively thinner higher up.
The drinking water tank was printed for 38 hours, but the process itself had to be interrupted, which translated into a total of five days of work to create it. TectorPrint material was used to create the tank. In total, the structure is seven metres high and has a diameter of 7.6 metres.
Our company has been developing 3D concrete printing technology and its applications for years, and the project in Barczewko is further proof that this technology has great potential. The use of our solution has resulted in material savings of 25 per cent, which is another step towards more sustainable and efficient construction, ” said Henrik Lund-Nielsen of COBOD.
The development of 3D printing technology makes it possible to automate the construction process and speed it up. A major advantage is the reduction of waste and the reduction of raw material consumption. Now the small village of Barczewko will be able to boast state-of-the-art solutions that are hidden beneath the surface.
