In the past, the 3d printer based on fdm technology will adjust the height of the nozzle after the completion of a layer of printing, and then come to the next layer of the start of the printing point, and start printing.
This way, there is a disadvantage, that is, in the printing of single wall design products need to set aside time to adjust the height and thus lead to a waste of time.
In contrast, spiral vase technology is to print a layer of dots while slightly adjusting the height of the nozzle, so that after printing all the dots of a layer, the height of the nozzle has reached the next layer, without leaving dedicated time to raise the height of the nozzle, thus increasing the speed of printing.
We can follow the instructions in the figure below to open spiral vase mode.
If the Spiral vase mode is not turned on, the height on the z-axis will not change when printing a layer.
If the Spiral vase mode is turned on, the height on the z-axis will rise as you progress when printing a layer.
