Minnesotan Andrey Rudenko has taken DIY backyard projects to the next level by 3D-printing the world's first concrete castle right in his own backyard! Drawn to 3D printing's seemingly limitless applications, Rudenko began developing a 3D printer two years ago in hopes of constructing inhabitable homes durable enough to stand up to extreme weather conditions. According to 3ders, this 161.5-square-foot castle is one of the largest objects ever created with 3D printing technology.

Rudenko created a 3D model of the castle in SketchUp.
Rudenko's grand 3D-printed castle and his self-built 3D printer was a labor of love.
After trial and error, Rudenko printed the castle from 10-millimeter high layers of precisely laid concrete that measure 30 millimeters in width.
He also added rebars into the bottom and top walls.
With his concrete castle test-run successfully built, Rudenko is now working to redesign his printer based on his lessons learned and has a near-term goal of 3D printing a full-scale livable house.
"My goal will be to print 24 hours a day until the project is finished," writes Rudenko. "I'm also planning to print the structure in one piece; printing the castle turrets by themselves was a bad idea as they were extremely difficult to lift and place."
Rudenko is also currently looking for collaborators and backers for his next project.
