What is a cantilever and how does it affect my object?

When there is a long thin surface of an object, it is possible that even-thou the powder in the printing block supports the object, there is a possibility that the object can warp or deform during the production process:

It is important to keep in mind that the object is to be printed into real life. Thus if a thin aspect is supporting something that is too heavy for it, it may break or deform,  even though the object looks perfect in your 3D modeling software ( an important factor is gravity, that is not applied to an objetc in a 3D software but does apply in real life). We recommend adding additional thickness to the areas that will get a lot of handling, or that support the most weight.

You need to also be aware that our solidity check tool does not detect physical aberrations such as floating parts, unstable position, parts supporting too much weight relative to their thickness, etc. Particular care must be given to the geometry of your design and the most stressed parts must be thickened:

This Cantilever issue is sadly a limitation with the 3D printing technology and depending which material you select this risk can change.
