Neutral Axis In 3D printing, the neutral axis is an imaginary line in a structural component under bending stress where no tensile or compressive forces occur. It is crucial in designing load-bearing parts, especially in FDM and SLA printing, where layer orientation influences mechanical properties. Engineers consider the neutral axis to optimize part geometry, ensuring stress distribution and preventing failure. By aligning the layers parallel to the neutral axis, they can enhance the strength and durability of the printed object. This concept is widely used in aerospace, automotive, and structural applications. |
