To make 3D prints watertight, it’s essential to ensure that the walls and layers are thick enough to prevent leaks. A simple rule is to use at least three walls with a total thickness of around 1.35mm if you are using a 0.4mm nozzle. This thickness should be maintained for all inner surfaces or any parts that need to be watertight. Additionally, the bottom and top layers should also follow this 1.35mm thickness guideline to avoid weak spots. It’s important to note that infill alone won’t make the part watertight; it’s the solid walls and layers that create a proper seal. For best results, use a layer height lower than 0.2mm, such as 0.1mm, to ensure a tighter, more consistent bond between layers. Sticking to these guidelines will help achieve reliable water resistance in your prints. Follow& check link in bio for more.
