Minimum thickness by technology
| Technology | Minimum | Recommended for load-bearing |
|---|---|---|
| MJF | 0.75 mm (down to 0.5 mm) | ≥1.5–2 mm |
| SLS | 0.75 mm (down to 0.5 mm) | ≥1.5–2 mm |
| SLA | 0.75 mm (down to 0.5 mm) | ≥1.5 mm |
| FDM | 0.75 mm | ≥1.2–2 mm |
Why walls that are too thin are a problem
- They can warp during production (heat, cooling).
- They break during cleaning or blasting.
- They cannot withstand the load.
How to check
In the configurator, switch on “Thickness” – the model is color-coded by wall thickness: red – thinner than recommended for the selected technology, orange – borderline, green – safe. This is an automatic warning; the final assessment is made by an engineer.
Flat surfaces and warping
Flat, large or thin structures should be reinforced with perpendicular elements (ribs) to limit thermal deformation during production.
