Germany's First 3D Printed Three-story Apartment Is About To Be Completed

Following the arrival of the first 3D-printed house in the world, a residential building with 3D printing technology in Germany will also be completed in the near future. In fact, as early as September last year, construction of the first 3D printed residential building in Germany began in Bavaria. Unlike the world’s first 3D printed house that has been occupied with a flat-layer structure, the structural design of this 3D printed house in Germany is amazing in all aspects: the three-story building can accommodate five apartments and the living area is about 380 Square meters, it is completed using a 3D construction printer called "BOD2".

Now, after ten months, the building is only five weeks away from completion. When it is completed, the house is expected to start receiving tourists from August. In addition to using the 3D printer "BOD2", the house was built by the construction company PERI, which cooperated with the Danish manufacturer COBOD, which provides 3D printers.

The print head used by the 3D printer "BOD2" moves along three axes on a solid metal frame. The frame ensures that the print head can be moved to any position within the structure and only needs to be calibrated once before construction begins. In addition, "BOD2" can analyze water pipes, circuits, and other utility pipes that will be added in the future, and work in such a way that it prints while completing other tasks in the print area. In this way, workers can print the main structure of the house while completing tasks such as installing pipes and connections that need to be completed manually.

"BOD2" can complete about 1 square meter double-wall printing work in five minutes at a speed of 2.2 mph (1 m/s). It is worth noting that this "BOD2" only requires two operators to use, and the operator can observe the print result only through the camera. The structure was printed using a substance called "i.tech 3D" created by Heidelberg Cement, which claims to have "excellent pumping and extrusion properties." The material is designed to meet the unique needs of 3D architectural printing, and obviously, it can work perfectly with BOD2.
