What feature should be used when the overhang of a part's geometry exceeds a certain angle?

When dealing with overhangs in 3D printing, the feature that should be utilized is support. Supports are structures that are printed alongside a component to provide stability during the printing process. They are particularly crucial when the overhang angle exceeds a certain threshold, typically set around 45 degrees. At this point, the printer may struggle to adequately deposit material without an underlying structure to hold it up.

Using supports allows the printer to create layers above the overhang safely by providing a temporary base. Once the printing is complete, these supports can usually be removed without damaging the final part. This ensures that the final geometry meets design specifications and maintains the necessary structural integrity.

Options like bracing, stabilizer, and shielding do not specifically address the need for a supportive structure beneath overhangs during the printing process. While they may serve other purposes in different contexts of design or safety, they do not specifically relate to managing overhangs in additive manufacturing. Hence, support is the most appropriate feature to be used in this scenario.
