1. A system for layer-by-layer three-dimensional (3D) printing of a 3D printed object, the system comprising:
a print head configured to print a plurality of layers to form the 3D printed object;
a print head follower assembly configured to be co-operable with the print head and configured to apply a degree of surface roughness to at least one of the plurality of layers after being printed and before the at least one of the plurality of layers solidifies; and
a controller configured to identify parameters of each of the at least one of the plurality of layers and configured to control operation of the print head and the print head follower assembly, wherein the parameters include the degree of surface roughness,
wherein the degree of surface roughness applied to the at least one of the plurality of layers provides an amount of gripping strength between the at least one of the plurality of layers and a consecutively printed layer of the plurality of layers.
