WebResolving the under-extrusion issue (refer to 3.2.1: Under-extrusion). Ensure that the wall thickness is in relation to the size of the nozzle. The wall thickness should be a multiple of the diameter of the nozzle thickness. For example, a 0.4 mm nozzle should have a wall thickness of 0.4 mm, 0.8 mm or 0.12 mm. WebFirst layer issues. This is by far the most common 3D printing problem, and probably the first one you may encounter. The first layer is the essential one because it is the base of the printed object. Therefore, if it isn’t perfect, the chance of print failure increases. Many common 3D printing problems stem from a poor first layer.
