Concrete has been used for many more complex lab-scale structures, with the finer precision than contour crafting, due to the smaller nozzle size. It has been implemented in several 3DP projects with normal strength concrete, but ultra-high performance concrete has also been successfully printed [[237], [238], [239]].
