At 5% infill, IвЂ™ve increased my top layers to 5 to be able to adequately cover each pass and that seems to work well enough. I use 5% infill for most of my big prints since the walls provide most of the structure but this does open up to some regular problems like top solid layers not having enough support to bridge over, leaving gaps in the top surface. The pattern you use isnвЂ™t as important as the density.With two perimeters, IвЂ™ve dropped prints from chest height, had them bounce around the concrete floor, and not even crack. One perimeter, while equivalent to three perimeters on a 0.4mm nozzle, you open yourself up to the possibility of gaps between the start and end of the perimeter. You donвЂ™t need as many perimeters to achieve the same strength, but you also donвЂ™t want to have less than 2 perimeters if you can avoid it.IвЂ™ve had even had layers separate at 230вЊ. This is because you are melting a lot more plastic at once and need even more heat to transfer to the filament AND ensure that it sticks to the previous layer. While the bed temperature wonвЂ™t need any changes, the nozzle temperature will need to be significantly raised from your usual usually PLA is printed at about 200вЊ, but I regularly print PLA at 250вЊ with a volcano.While this does give the 3D printer the ability to print thicker layers, there are some settings you will need to think about differently with a 1.2mm nozzle than with a 0.4mm nozzle: With the Volcano hotend system, the nozzle is longer to give filament more time to melt and the heater cartridge is parallel to the filament path (as opposed to perpendicular like on the v6) to improve the heat transfer from the cartridge to the larger heater block.
