For the last two years, Andrey Rudenko has been 3D printing a concrete castle in in his yard, layer by layer. Now, his castle is finally finished.

Andrey shared pictures of his process over the past two years to mixed reactions from the 3d printing community. While some may have thought he was headed off the deep end, many were enthralled by his progress and eagerly anticipating each update.

His printer is completely custom built and able to spit out concrete reliably thanks to tons of trial and error. His current settings give him layers that are 10mm tall by 30mm wide. He mixes his own concrete to make sure that it is the exact consistency he needs to avoid clogging his print head.

As you can see in these pictures, it looks like it works just like your standard desktop printer, though occasionally he has been adding a bit of rebar to help reinforce the structure. He says that the next time it would be nice to print all of the pieces in place because moving the turret bits that he printed elsewhere was very difficult.

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.

As he completed this project he also finally put up a website to show off his machine and hopefully connect with architects who would like to collaborate.
