SEM image of the 3D Printed structure with ink containing 10% CA on the glass substrate with a 3–9 capillary. (a) Width of the printed strands in pattern two is 8 µm in the first layer and it reduce to two µm on a top layer. (b) The first layer and (c) the top layer of a structure printed with a 3–9 capillary. The strand placement varies between layers and it is most probably caused by capillary bending due to wetting force.
