Guy 3D Prints an Actual Castle Using Concrete

Andrey Rudenko has built a castle in his yard. Well, actually printed a castle in his yard is more accurate.

It took him 2 years and a precise concrete mix to produce the layers upon layers that he needed.

According to Makezine:

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.

And here’s a video of the printing in action!
