The First 3D Castle Concrete Printer Has Been Revealed!

This project is anything but you can actually walk inside this castle; it’s going to be more than 10 feet tall when it’s finished. The massive printer that’s laying down the concrete castle is the creation of Minnesota engineer Andrey Rudenko.

Andrey Rudenko’s story: “It has been two years since I first began toying with the idea of a 3D printer that was capable of constructing homes. In my vision of using 3D printers as new technology, I wanted a light, portable, and stable machine. First, I built a small 3D printer that used plastic for its main material, and from that, I started experimenting on enlarging the printer and using variations of cement mixes. Layering cement was an extremely difficult task- it required extensive tuning of the printer on a programming level, as well as using exact quantities for the cement mix. While testing the printer, I ran into obstacles (such as the nightmare of the extruder clogging) and discovered even further abilities of the printer, like that it can print much more than 50cm a day as I originally thought. I was able to calibrate the machine so that it prints nearly perfect layers now, and I played with various heights and widths of the cement layers. My current standard is 10 millimeters in height by 30 millimeters in width, but countless other options are available with just the click of a button”.

“​This two year long journey has led me to build the world’s first 3D Printed Concrete Castle. Finally, it stands”!

“The new 3D technology allow to implement completely new architectural ideas in construction and it is remarkable how we can vary the current architectural structures of homes. With this new technology, it is possible to print limitless amounts of classical décor as well as brand new elements and shapes, whereas previous technology made innovative constructions difficult and expensive”.

“A new era of architecture is inevitable, and I’m excited to see where the next few years will lead in terms of construction and design. I have previously been sure I could print homes, but having finished the castle, I now have proof that the technology is ready”.

Printer builds concrete insulated walls in a shape controlled by G-code. The printer is built to withstand real-world conditions and the video captures printing in winter temperatures (slightly above 32 °F or 0°C). In preparation for the first house printing, this video shows several practice runs with various shapes and elements.
