Underhang An underhang is the opposite of an overhang, occurring when a model's feature extends inward or downward, creating unsupported geometry. It poses challenges in printing without internal supports, leading to sagging or poor layer adhesion. Proper print orientation, infill patterns, and multi-axis printing strategies minimize underhang challenges. Advanced slicing software detects underhangs and generates optimized internal supports. Proper settings enhance dimensional accuracy, structural integrity, and surface finish. Managing underhangs expands design possibilities for complex geometries, functional parts, and artistic models. |
