Why is bridging important in FDM?

Bridging is a crucial aspect of Fused Deposition Modelling (FDM) because it allows the printer to create structures that span gaps without the need for additional support material. This capability significantly impacts design flexibility, enabling designers to create more intricate and open geometric shapes without worrying about the necessity of support structures that would otherwise be required for overhangs or wide gaps.

In essence, a successful bridging technique can lead to cleaner prints, as it avoids the issues related to removing supports after printing, which can often mar the surface finish or lead to structural weaknesses. Designers are thus empowered to experiment with complex designs, knowing that bridging can help achieve their artistic vision without compromising on build quality or requiring a more complex post-processing stage. This optimization in print design not only enhances the functionality of the printed object but can also contribute to time and filament savings, as less material is consumed in producing support structures.
