When you print another layer of plastic on one layer, you need to make sure that the new layer is pressed onto the lower layer so that the two layers can stick together.


However, these small nozzles also lead to a limitation of the height of the floor. Plastic extrudes from this tiny hole to form a very fine squeezed thread, which can build more printout with rich details. Most 3D printer nozzles' diameter are between 0.2 and 0.6mm.
