We printed a 4 foot tall structure that we later partially applied stucco on (so as to display both the printed surface and the finished surface). Here below are a few images of the print.
Important areas to pay attention to:
1) Outer walls of the print surface are finished off with a beautiful white stucco giving a clean finish.
2) The inner cavity of the prints are intentionally 3D printed "void" so as to be filled in later with a high strength, reinforced concrete mix a structural engineer approves.
Lastly, here below is the printer in action printing part of this structure.
