Define "supports" in the context of FDM printing.

In the context of Fused Deposition Modelling (FDM) printing, supports are defined as structures printed to stabilize overhangs. When a model has parts that extend outwards without any material beneath them, these overhangs can be prone to sagging or failing during the printing process. To combat this issue, supports are created as temporary structures that hold up these overhanging sections until the print is complete. After printing, these supports can typically be removed, leaving behind the intended design.

The function of supports is essential in producing high-quality prints with intricate geometries. They ensure that the layers of filament have a solid foundation to adhere to, thereby enhancing the overall stability and integrity of the finished item. This is critical for achieving accuracy and preventing defects in the final product, especially in designs that involve complex shapes or significant angles.
