As explained in the 3D printing page, supports are sometimes required to support overhanging sections of a print. Due to the downsides of supports discussed below, it is typically better to avoid supports altogether when designing for 3D printing.

====Form and smoothness====
====Form and surface roughness====
Supports will also require post processing such as removal and sanding (if a nice smooth finish is desired). When designing for mechanical assemblies, it is important to keep in mind that supported sections might sometimes sag slightly, affecting the form of the surface being printed. Therefore, when designing (modeling), make sure that interfacing geometries (those for which the correctness of the shape, or form, is critical as it is interfacing with other parts) are not overhanging.
