- When deciding on the WALL thickness of your print, there are a few important things to keep in mind.
- First of all, if you have an extremely detailed model of a building, for example, scaling the model down for 3D printing will scale every aspect of the model down including minuscule details and wall thicknesses. There comes a POINT where the 3D printer is no LONGER capable of printing such fine details. That can result in super fragile prints and missing details. Therefore, while preparing a file for printing it is important to know which parameters to alter in order to ensure a good result.
- The next aspect to consider is the material and technology you are using. Certain materials will remain stable at thinner wall thicknesses than others. User guidelines should be provided by the FILAMENT manufacturer.
- Using FDM technology, the minimum wall thickness typically lies between 0.05mm and 0.1mm – depending on the resolution your 3D printer supports. However, this doesn’t mean that walls printed at that thickness will be stable at all.
- The shape of your 3D model is also a critical aspect. For example, if your 3D model has a part with a lot of overhang, the structures supporting that overhang will need to be thick enough not to warp or break. Also, you need to make sure that supporting walls are strong (thick) enough to hold the weight above it. Generally, 1mm is the lower limit for wall thickness and 2mm is recommended.
