Additively printed cementitious structures and methods of manufacturing same

A method of manufacturing a cementitious structure for supporting a wind turbine, the method comprising:

• additively printing, via an additive printing device, a first portion of one or more contours comprising a cementitious material so as to form a first layer of a cementitious structure, the first portion of the one or more contours comprising a first plurality of contour coupling features;
• allowing the first layer of the cementitious structure to at least partially cure, and
• additively printing, via the additive printing device, a second portion of the one or more contours comprising the cementitious material so as to form a second layer of the cementitious structure, the second portion of the one or more contours comprising a second plurality of contour coupling features that engage with the first plurality of contour coupling features so as to mechanically couple the second layer to the first layer.
