These are just some of the effects: +* Having thinner layers will increase the visual quality of the print. Since the layers are thinner, the stair stepping effect at the layer's borders will be reduced. Also, the layers will be closer together and so the creases in between the layers will be smaller, leading to an overall smoother finish. +* Having thinner layers allows the printer to produce more detail on the top and bottom sides of your print. +* Having thicker layers tends to make the print stronger, to a point. There will be fewer borders between the layers, which tend to be a weak point. The thicker layers will not shear as much. +* Having thicker layers will reduce printing time, because the nozzle will not have to make as many horizontal movements. + +Many settings depend on the layer height. Because layer height significantly affects the flow rate of material through the nozzle, many parameters of the printing process will change. This is very complex. For instance, when increasing the layer height, you should probably increase the printing temperature slightly to offset the extra rate of heat loss. The temperature then affects the liquidity of the material which will affect how sharp your corners will be and what cooling is needed, and so on.
