Draft Angle A draft angle is a slight taper or incline added to vertical walls in 3D-printed models to improve their manufacturability and ease of post-processing. Draft angles are particularly important for parts designed for molding or casting, as they allow the model to be easily removed from a mold without damaging the surfaces. In 3D printing, draft angles help reduce the need for supports, improve overhang quality, and minimize layer separation. Typical draft angles range from 2 to 5 degrees, depending on the material and the complexity of the geometry. Incorporating draft angles during the design phase enhances printability and reduces the time required for post-processing. |
