This guy 3D-printed a castle in his garden

A full two-storey house is next.

A former contractor in Minnesota is working up to 3D-printing a full-sized house, but he decided to start with a castle instead. Andrey Rudenko, featured on, recently developed a custom 3D printer that uses a form of concrete rather than a standard plastic filament and set it to work in his backyard.

The result? A modest micro-castle that serves as both a proof of concept for Rudenko’s large scale plans and a completely badass clubhouse. Given his background in engineering and contracting, the structure boasts a level of structural integrity and design superior to other house-printing efforts, like those zany slapdash tiny houses in China.

After spending a few months working on the mini castle, Rudenko will set his sights on a much bigger project: 3D-printing an entire two-storey house. Rudenko believes his method, modified from open source plans available on RepRap, to be superior, if slower. His technique lends a smooth, high-quality texture to the walls.

“While other teams are also working on respectable projects in 3D printing construction technology, I have developed a product that is ready for actual-size construction rather than miniature prototypes,” Rudenko said, in a conversation with “A cheap house built in 24 hours is not my goal. As an experienced builder, I know that to avoid problems in the future, it is more important to produce homes of a good quality, which may take longer to build than cheaper homes made quickly.”
