This Engineer Just Built An Amazing Castle In His Backyard

Now all he needs is a moat.

Minnesota engineer Andrey Rudenko has an idea that could change housing forever. 3-D printed homes. After working small scale 3-D printing projects, Rudenko wants to take things to the next level.

He's already created this majestic 3-D castle.

On his site, Rudenko writes, "It has been two years since I first began toying with the idea of a 3D printer that was capable of constructing homes."

Each component was created using this 3-D printer.

He continues, "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."

According to Rudenko, "this 3D House Cement Printer is built to print medium-sized homes. The printer"s design is based on the harsh realities of the construction world, taking into consideration environmental factors such as temperature variability and strong winds."

Insulated concrete was used as the material.

Rudenko outlines his idea for the future of printed housing, saying, "3D printing in construction will not wholly replace previous techniques, and materials such as brick will continue to be utilized. Rather, 3D printing will significantly supplement the manual work. The technology aims to considerably lower production cost, provide a safer and more comfortable building process, and allow for much more architectural flexibility."

The walls are strong and durable.

He adds, "A 3D house made out of insulating concrete forms will be warm and durable, as well as less susceptible to damage from earthquakes, floods, hurricanes, fires, and other natural disasters. "

Speaking of his problems with bringing the project to life, Rudenko adds that "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 50 cm 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. "

Coming together. Looks a bit like a labyrinth.

One of the concerns was whether or not the printer would work in freezing temperatures. Luckily, it does. Rudenko says that "printing at zero degrees may take longer than printing during a warm temperature but attains equally good result." This is good news for those in cold climes, but it also means being able to build outdoors year round.

Gothic archways lend more support to the structure.

On warm days, each layer has plenty of time to harden.

Here you see various components that will be added later.
