If you are already familiar with the leveling process of FDM 3D printers, it’s essential to know that the process is a bit different in resin 3D printers. This is because of the differences in how those two types of 3D printers operate. In FDM 3D printers, leveling involves adjusting the build plate to be at the correct distance from the nozzle. But for resin printers, it typically consists of changing the height of the build plate and the position of the resin vat.
