What are "self-supporting structures" in additive manufacturing?

Self-supporting structures in additive manufacturing refer to designs that possess enough stability and geometric characteristics to maintain their integrity during the build process without the need for additional external supports. This attribute is particularly significant in additive manufacturing, as the layer-by-layer construction method allows for complex geometries that can often rely on their own form for stability.

These structures maximize material efficiency, minimize post-processing time, and reduce the overall printing cycle time, making them highly advantageous in various applications. The ability to produce self-supporting designs is influenced by factors such as the angle of overhangs, the geometry of the part, and the material properties, enabling manufacturers to create more intricate and innovative designs without compromising structural integrity during the printing process.

While temporary support structures might be necessary for some complex designs, self-supporting structures eliminate that need, providing a streamlined approach to additive manufacturing.
