The risks related to thin walls and fragile features are common in additive manufacturing. Known as “feather edges,” these are very thin areas in 3D design files that are below printer tolerances for integrity and stability in the piece. These areas can cause issues, such as deformities, making part of the piece fragile, or destroy the integrity of the part altogether if the feather edge is not rectified.
