High-tech meets old-fashioned building material. The result is a stunning backyard castle, which is probably the best example yet of using a cement 3-D printer.
Architect Andrey Rudenko, of Minnesota, whose work was first reported by 3DPrint.com, used his own custom-built 3D printer to create the castle. For construction, he used a quick-setting mix of concrete and sand that prints in layers 10 millimeters tall and 30 millimeters wide.
Rudenko is not the first person to try a cement 3-D printer, but his work is drawing more praise and attention than other attempts.
And he’s just getting started. His next goal is to 3D-print a two story house, including the roof, with the castle functioning as a test-run to calibrate his printer and his construction techniques.
Cement 3-D printing is a new wave in its infancy. Earlier this year, a Chinese construction company showcased 10 small houses that they 3D-printed in less than 24 hours. Architects in Amsterdam are now building a canal-front house with 13 rooms.
“It has been two years since I first began toying with the idea of a 3D printer that was capable of constructing homes,” Rudenko told 3dprint.com.
“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 50cm 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.”
